Solid state relays have several advantages over mechanical relays. As the switching element is a triac (two thyristors back to back) it would only be able to turn on a DC load, not turn it off. I know that the coil versions are specific to AC but what about this one? This relay is a huge upgrade over the mechanical relays you might be used to (no clicking, much more reliable). They failed in the "on" state which was disconcerting. Anyone have an Eagle library for this yet? You hook the cathode up to ground, and hook the anode up to an Arduino output with a resistor in series - about 220 R or 330 R or so, maybe 470 R or 1 k if that's all you've got laying around. The peak-to-peak voltage, being twice this, is about 340 volts. A decent solid start relay for sale? I'm also curious about that diode. Datasheet says typical voltage to turn the relay on is 1.2V, and current is 20mA. I'm using this relay to switch the 120v power to the mercury vapor street light. A solid state relay (SSR) allows you to control high-curent AC loads from lower voltage DC control circuitry. Please see all COVID-19 updates here as some shipments may be delayed due to CDC safety and staffing guidelines. 1. I ordered one of these as a trial and so far is operating fine after several months of continuous use and a year later. These relays are Qwiic enabled which means they are plug and play, and now with their very own library it's easier then ever to get started. If it requires power, you need to know how much, what all the pins do, and how to hook it up. * Heatsink is pretty much optional. I used an Arduino Nano with one of these to build a cycle timer. If you are in a country where one side of the 240V is ground-referenced, then you would only need one. Jul 16, 2020. Also, because there's no moving contacts, solid state relays can be switched much faster and for much longer periods without wearing out. Me and Mrs. Jonesing. The board features two 25A/250VAC solid state by Member #795668 May or may not be worth keeping in mind for your circuit. That's particularly important if you're trying to control something like a hot plate, which invites a huge current surge when switched on as the input AC approaches a peak value. Any solid state relay that's controlling more than a few watts will need a heatsink. by Member #710419 Agreed! 2.0) KIT-13815 . But when I'm dealing with 110VAC, don't think a breadboard would be capable of handling a lot of power. Using these with a MSGEQ7 to drive christmas lights and I'm pleasantly surprised at how well they work. I've used a few of these with PID controllers to switch heating elements (in a sous vide cooker, and an espresso machine, both 120 V AC) -- it handles lots of AC current, silently; even with high loads, the SSR doesn't get very warm. Read the derating curves on page 6 of the datasheet or you will let the smoke out. I have used the relay extensively for two weeks now and have had no issues. (Hint: This device is little more than an LED and photo TRIAC and can easily be done that way- but you see it in a similar convienient package...). by Member #811852 If supply voltage is 3.7V and the relay needs 1.2V input, the voltage across the resistor should be 2.5V. You may need to provide your own basic tools like a screwdriver, hammer or scissors. Aug 20, 2020. And it works! TL;DR you cannot reliably trigger this with a 3.3V GPIO (it will be modulated or not trigger at all). verified purchaser, about 5 years ago So far so good. Touchless light show with the Qwiic Dual Solid State Relay Working from home is not without its difficulties, but with just a couple of proximity sensors and SparkFun's new Qwiic Dual Solid State Relay, you can create a light show with a wave of your hands. Worked perfectly for what I needed. Thanks to the fact that the two sides of the relay are photo-coupled, you can rely on the same type of electrical isolation as in mechanical relays. The SparkFun Qwiic Dual Solid State Relay is built on a similar design to our Qwiic Quad Relay and uses an ATTiny84 to act as the "brain" for the board. Contribute to sparkfun/SparkFun-Eagle-Libraries development by creating an account on GitHub. SparkFun's Public Eagle PCB Footprints. about 5 years ago Hi there! Anyone who thinks it would be better to do this using the audio signal itself, I have no clue where to begin with that so I am just going to do it this way. So, I ordered this one. The 3.3VDC output from the Photon activates the relay every time and the Particle cloud is easy to use and monitor. After a year of use I figured it was safe to offer some feedback as most folks are running << the rated current/power of the device I find. verified purchaser, about 2 years ago This is the smallest sold state relay I found and it is very nice and easy to install.. about 5 years ago Quote. Sewing may be required, but only with included patterns. One such advantage is that they can be switched by a much lower voltage and at a much lower current than most mechanical relays. If the switch or relay is on, CFL should turn on. about 6 years ago Initially, I was wondering why it was AC only and then I realized that when you switch off the relay, it is only changed once the load passes through zero volts and goes negative. The big difference is the current rating. For remote switching of non-trivial AC applications, this relay can't be beat. a) As others have said, because it's a triac-based device, it can not be used on a DC load. But a 3.7V power supply should be plenty. The caveat to that, though, is if/when they fail due to overheating (see dnear1's post) is that you can't tell what's going to be connected to what after meltdown (literally for me, in one case several years ago). Been using it with 120v 60hz and now 50hz without issues. about 2 years ago This is a robust device, at a good price. If you have an order or shipping question please refer to our Customer Support page. Anyone know of a good alternative to one of these. the tilde on the ic package labels it for ac, but what would the dc limits be, if it will even accept dc? To the guys looking for a way to make a light dimmer: you won't make a proper dimmer by just getting a non-zero-crossing version of this one here - you'll have to drive it with a zero-crossing sensing circuit. by Member #377250 about 3 years ago I chalked it up to carbonized plastic. Yes, that it is, but you have to design up the circuit, etc. I will be using this value, and map its variation to a 0-255 range so that i can use it to power a relay to control a 120 volt circuit. I am switching two legs of 240 volt AC for a well pump. by Member #1458351 by Member #339294 But I'm not aware of that. verified purchaser, I used this item to build a controller for my woodworking shop vacuum. These particular solid state relays can switch 400VAC and 8A. in its parameters and connection diagrams your questions may already been answered. 1pm to 5pm U.S. Mountain Time: This product has shipping restrictions, so it might have limited shipping options or cannot be shipped to the following countries: Added to your It's not as "plug-and-play" as this one here as it requires some external circuitry like the optocoupler on the input and an external power triac to trigger (it doesn't carry the current by itself). verified purchaser. This particular model only turns on during the times when the AC voltage is at 0 v, which is twice per cycle, or 120 times a second. Each relay is rated to 40A @ 28-380 VAC so with all four on board you can control some serious power all from the easy-to-use Qwiic Connect System. IMO don't go 8 amps with these, stay below 5 amps (use a heat sink above 2 amps). : 1. See all skill levels. Where electronics enthusiasts find answers. Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. I've found that using one of these with ~4-10A of current will cause the relay to get pretty warm, but simply bolting it to a piece of metal helps tremendously, as the whole bottom plate is metal. If I wanted to control a normal 240V circuit, would I need two of these? New Product. about 5 years ago If you try to run 2 off the Arduino with only the USB it can't quite power them. Crap. Worse than that, since the triggering element is zero crossing, it would not switch on until ... power is removed ! by Member #871262 Using a toaster oven that draws about 10 amps AC at 120 volts. The SparkFun Qwiic Quad Solid State Relay Kit uses the best solid-state relays in our store and provides a single PCB to place and control up to four of them via I2C from your microcontroller.. If you're putting 40A into it, yes, you will need a heatsink. The kit is more than twice the cost, and this one does not require me to build it. Be mindful in your design process and this is a great buy, just don't expect mechanical relay power performance without some serious effort on your part. What you're looking for is an N-Channel Logic Level Power Mosfet. by Member #391646 2 posts; 2 posts; Solid State Relay? verified purchaser. When these are used with higher power devices, a heat sink is recommended. verified purchaser. Solid State Relay? Pricing and Availability on millions of electronic components from Digi-Key Electronics. if so, how can i calculate the RL? by Member #1184351 I should have read this earlier concerning hooking it up like an LED, now I burned up 2 relays without knowing why... Can these be used in parallel to increase the maximum current allowed? Going to buy two of these tonight, also going to buy a thermocouple and thermocouple breakout. This relay is the switch between an arduino and a space heater. We bought 35 pieces but haven't had a chance yet to put them to work. Min. I'd recommend basing your heat sink calculations on something higher - 100-150 watt so it doesn't get so hot and can rely on convection rather than needing a fan to cool. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current. Using it to switch 150 watt resistive load - rather tame for the 8 amp rating so there is no heating issue. As a DC load does no such thing, this device can switch it on - but not off. 120 V (USA) or 230 V (Europe), are almost always quoted in RMS values, and not peak values. Can I use it from raspberrypi (3.3v) to drive a DC circuit at 12v? A similar calculation indicates that the peak-to-peak mains voltage in Europe is about 650 volts. Wired this into an outlet box to turn on outlets using the 12V trigger from my surround sound receiver. Each one of these relays is equipped with four screw terminals (for use with ring or fork connectors) and a plastic cover that slides over the top of the relay to protect the terminals. SparkFun Beefcake Relay Control Kit (Ver. Description The SparkFun Qwiic Quad Solid State Relay Kit takes one of our favorite solid state relays and lets you place up to four of them on a single PCB to control all … SparkFun: SparkFun Accessories SparkFun Qwiic Dual Solid State Relay. CF by Member #191965 by Member #700219 Will you comment then on who or what is right for RMS 240 Volts ? Edit: Got ahead of myself there. by Member #677330 please stock the device version that has the zero crossing detector. Just check the data sheet before selecting it--it says 3mA leakage. by Member #169074 Favorited Favorite 29. a lot of the other relays i looked at needed 5v for input. by Member #195567 Used my one spare to check circuit changes and works great. Solid State Relay. first thing I looked for was if the device would wait to switch at zero crossing. However it takes about 12mA to switch the solid state relay, so do check that your board can supply that amount of current from a digital output. but I bought 2 more. Happy New Year from all of us at SparkFun! I like the heat sink and plastic cover for safety. Favorited Favorite 23. http://www.instructables.com/id/The-inner-workings-of-Counterfeit-FOTEK-SSRs/[/url]. There are advantages and disadvantages either way, but we need to know which it is to properly identify what it is suitable for? verified purchaser. : 1 Mult. AVR Atmel. Each relay is rated to 40A @ 28-380 VAC so with all four on board you can control some serious power all from the easy-to-use Qwiic Connect System. The data sheet says the minumum "load supply voltage' is 80V. Running two relays with only 11amps at 240V, these relays (2 of them) had the sides of the housing slightly melted and literally burned black rectangles into the plywood piece they were bolted to. I want to know when SparkFun will start carying the infinite heatsink mentioned in figure 2 of the datasheet. Been using it a couple weeks now, and it is functioning perfectly. There will still be a very slight leakage through the Snubber circuit, so never touch the wires with it connected, even if the relay is 'off', always make sure it's unplugged before working on it. Mouser Part # 474-COM-16810. about 6 years ago Instructions will be included and easy to follow. Thus the peak value of the mains voltage in the USA is about 120 × √2, or about 170 volts. I am planning on designing a Photon controlled toaster oven reflow. Not like in case of soldering stations you carry, where the voltage info is just barely mentioned somewhere within the description. DC SSR is essentially just a MOSFET... Google 'MOSFET as a switch'. The device is functions as expected and it is clearly marked for AC loads by Sparkfun so this is just me pointing to the obvious. Solid State Relay - 40A (3-32V DC Input) This particular SSR can switch current loads of up to 40A with a 3-32V DC input and a zero cross trigger control method. Le kit de relais à semi-conducteurs SparkFun Qwiic Quad prend l’un de nos relais à semi-conducteurs préférés et vous permet de placer jusqu’à quatre d’entre eux sur un seul circuit imprimé pour les contrôler tous via I2C à partir du microcontrôleur souhaité. If you connect them to a load that's powered by DC current, you can turn the relay on, but you can not turn the load back off again without disconnecting power elsewhere from the load. Check the example layout we linked to. This tutorial will walk you through making a timed power controller for interactive projects. The SparkFun Qwiic Dual Solid State Relay is a power delivery board that allows users to switch two AC loads from a low power microcontroller using the SparkFun Qwiic connect system. New Product. verified purchaser. images are CC BY 2.0. The actual download link still points towards his GitHub repo, which is no longer present. You can export the part and footprint using the standard eagle ULP. by Member #171000 Does the zero-cross trigger mean that a simple IO needs to be toggled in order to switch the SSR from on to off, or do I need to put a PWM signal that corresponds to the AC line? As it would not be easy or inexpensive to re-wire the lighting and it is a MakerSpace, I decided to fabricate an IOT solution using a pair of Particle Photons, this SSR and a NO push button. Why is that in the sample circuit? Happy New Year from all of us at SparkFun! verified purchaser. We welcome your comments and suggestions below. about 5 years ago Note that it won't actually be strictly 'Open Circuit', even with one in each phase. Commanding the device on and off 10 times a second is not a problem at all. and handle quite a bit of amperage. Pros/Cons? ACZCPWM makes accurately controlling these possible (and easy). Just make sure to have a DC power supply hooked up to the Arduino and it works great. They make these nifty packaged up devices that don't need a circuitboard, trying to figure out the resistances needed, etc. They accomplish this by using infrared light as the 'contact,' a solid-state relay is really just an IR LED and a phototriac sealed up into a little box. A solid state relay (SSR) is just what it sounds like; an IC that acts like a mechanical relay. This unit is sturdy and built really well. Are there any problems using those, that I'm not seeing? That is, switch and relay should be connected in parallel like a LOGICAL OR GATE. by Member #1146265 I was concerned about heat because I mounted the relay inside he machine, but I have had no problems. Relay SPDT Sealed COM-00100 . It is NO. I saw heatsink specifically for these types of SSR online so I tried rigging an old CPU heatsinkg ... but still didn't feel safe until I moved my 240 volt 1500Watt (6.25 AMP) load back to a beefcake relay :-) ... maybe SF can source us a good matching heatsink those that need high speed switching or high switching count :-). verified purchaser. Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Can anyone send me a circuit diagram and information about what sort of relay I should be using. Also, because there’s no moving contacts, solid state relays can be switched much faster and for much longer periods without wearing out. Although they didn't burn up they failed on for my application in hours or days. Note that it also requires a driver circuit and the external wire connections are the same as the relay board. by Member #630068 Has been working perfectly! SparkFun Electronics SparkFun Accessories are available at Mouser Electronics. verified purchaser. Hello, question: The datasheet says that the minimum trigger current, under this conditions VD=6V, RL=30Ω, is 8 mA, i'm a chemical engineer and i don't know much about electronic circuits, so help-me out here.... i'm assuming the RL is the resistor shown on pg 9 connected to the VCC. In that way also, could a PWM signal be used in order to vary the output load current? verified purchaser. Do these "Al plates" described need cooling fins, or is just a smooth lunk of metal sufficient? about 2 years ago The indicator LED is useful to check that the SSR is getting the control signal. Remember to always read the datasheet when uncertain. I'll own that in this case- but I've bigger fish to fry and have limited resources (time being one of them...) on a project of moderate import to a lot more than just myself. I always have a huge amount of trouble finding SSRs. It is there most likely in cases where the relay is being triggered by a microcontroller, as when the microcontrollers effectively turn "off" a load, they actually send signal 0 which to the microncontroller is ground - 0 v. So it simply reverses polarity in the 5V circuit, this could cause damage to the solid state relay, so the diode prevents this from being a problem since current can only flow in the correct direction with the diode in place. You do not expect to run much with one this small, so you do not push it. If you have an order or shipping question please refer to our Customer Support page. about 2 years ago Somewhere. I guess some of it was lost in the Chinese translation.... ). If you look at the diagram below the chart on page 3 of the datasheet, there is an internal block labeled "Zero Cross Circuit" so it looks like this is a zero-cross version. SparkFun Single and Qwiic Quad Relay Arduino Library The Single, Dual and Quad relays make it possible to control high powered devices using a low powered device like an Arduino. Also easy to wire up. You just made my day Sparkfun! The SSR is installed with a heat sink and some attention to the instructions. It uses a Sharp SSR module and can switch 125VAC at 8A (AC only - not DC). SparkFun Quad Solid-State Relay Kit (Qwiic) – Sparkfun KIT-16833. To calculate the value for the resistor connected to Vcc (R1 in the diagram), use V=IR. Cons of the kit: SparkFun Electronics Accessories SparkFun Accessories are available at Mouser Electronics. Hi, as stated in the datasheet, it mentioned it has high isolation voltage between input and output. I generally calculate the load current and multiply that by two, and then use a heat sink anyway. They package them up for people for just this reason and it'd be nice to be able to have a one-stop shop for this stuff. Your post implies you've used these before. Sparkfun, where do you get your SSD's from? If you want to make your own "marginal" heat sink, cut a small piece of extruded aluminum angle or C-bar and adhere it on. I don't know where you get your math from, but it's definitely not the same one the rest of the world uses. * Expense. I had a couple of the $US5 "Fotek" fakes I got off Ebay. I bought this part as an easy way to control some grow lights remotely (no I don't live in CO, so not that kind of growing). Thanks. about 2 years ago by Member #536848 It also says the maximum zero crossing voltage is 35V, so at 24V it may not "see" the sero crossing and never turn on. I don't think resistors come in 125ohms, but 120ohm or 130ohm should work just fine. The load being switched is a 4800W immersion heater at 240V. by Member #735257 I am running a fan with one at 230V 1.7A (>10A for very few milliseconds during startup). verified purchaser. verified purchaser, I lost both due to error in circuit. The solid state relay can be controlled with 3V, so is suitable for the 3.3V arduino boards. heaters, pumps, lights. Hooray! Google the U2008 IC instead. I have the relays mounted on a heat sink appropriate for 15 watt heat dissipation. Can i use one lipo (3.7V) as power supply? And if you're adhering, make SURE it's a thermal adhesive like Artic Alumina. We love it so much we've designed the SparkFun Qwiic Quad Solid State Relay Kit. about 2 years ago Solid state relays have several advantages over mechanical relays. Thanks! Peak values can be calculated from RMS values from the above formula, which implies Vp = VRMS × √2, assuming the source is a pure sine wave. Learn More. Don't even get warm with 100 bulb strands. 2. A couple of comments to help people use these: Mine are running at less then 20amps and work very nicely. Any idea what the leakage current of the triac is? The SparkFun Qwiic Quad Solid State Relay Kit takes one of our favorite solid state relays and lets you place up to four of them on a single PCB to control all of them via I 2 C from your desired microcontroller. I would also love a DC version, I do fun stuff with the Rebel LEDs. thanks. * The kit is substantially smaller. One could use a motor controller, but it's not really designed for switching there, they are designed to control brushed or brushless motors which is a differing beastie than a "relay" is. I'm using a tiny arduino to turn a street light on and off using a Cadmium Sulfide Cell. Shop all products from SparkFun Electronics. images are CC BY 2.0. verified purchaser.

Please see all COVID-19 updates here as some shipments may be delayed due to CDC safety and staffing guidelines. We've done it before at work. The datasheet shows you the recommended heat sink for this product. Datasheet mentions 1.6v drop on the AC side at room temperature. If you follow up the link, this is the class of device I'm referring to (And needing- yes, I'm trying to switch that much current...7 times over...). By the way, these are listed as obsolete by Digi-Key - they list the S202S02F instead. by meljr by Member #1373653 One such advantage is that they can be switched by a much lower voltage and at a much lower current than most mechanical relays. Do I need transistor? So 230 * 1.414 is between 325 and 326 volts, well within the range of this solid state relay (with almost 75V safety margin...). Part # COM-16810. Will this damage the relay or is there any chances for other damages ? verified purchaser. Contribute to sparkfun/SparkFun-Eagle-Libraries development by creating an account on GitHub. Perfect for my application at a reasonable price! So from https://en.wikipedia.org/wiki/Root_mean_square Great device but - RTFM - only works for AC loads. Is that a typo? by chipmc is this correct? They allow you to control high-voltage AC loads from lower voltage DC control circuitry. I'm just throwing in a vote for carrying a DC SSR as well. A a footnote, Sparkfun should pay a little more attention to the customers from 230V parts of the world. I'm putting them in fluorescent ceiling light fixtures so that when the projection screen is lowered the lights go off. To allow for faster and quieter switching of the load, this board uses solid state relays instead of electromechanical relays. I originally bought another very similar SSR, also rated for 3~32VDC on the control side. The SparkFun Qwiic Quad Solid State Relay Kit takes one of our favorite solid state relays and lets you place up to four of them on a single PCB to c… There's no mention of a heatsink being required in the description. The new form factor (P/N S202S02F) fits a TO-220 heat sink perfectly, whereas this older design not as well. by ROB-24601 September 29, 2020 08:22 Pacific Daylight Time 0 I had thought about this. This relay works as advertised, is completely silent and runs cool to the touch. More importantly though, the datasheet does not specify whether the switched voltage is ac or dc. verified purchaser. My heat bed is running on AC and the relay is in the primary of the step down transformer I'm using. by Member #1111055 I didn't measure it, but with an LED lamp attached, it could charge up and flash the lamp every 5 sec when OFF. Sorry, could not get the formatting to work and gave up. Each one of these relays is equipped with four screw terminals (for use with ring or fork connectors) and a plastic cover that slides over the top of the relay to protect the terminals. I needed an easy way to disconnect RV power after I had already climbed into my bunk. This S108T02 is the zero crossing version ... the S108T01 is the non zero crossing version. I was able to add an AC switching element to my board very quickly. verified purchaser. It worked perfectly as soon as I wired it up.
