by Member #169074 ", So these are not good for 240 Volts like we have in Australia as the peak to peak voltage can be 650 Volts. This is handy for controlling vacuum tables, coolant pumps, heated 3D printing beds, dust collection and much more with GCode commands. verified purchaser. I think most solid state relays come on at about 3V, and you don't want to exceed 20-24V (check the datasheet). 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. by Member #1146265 It's a cool phase-control IC. The purpose of the resistor is to set this current at around 20mA. It needed closer to 5v to activate. Been using it with 120v 60hz and now 50hz without issues. THIS PART CANNOT SWITCH DC LOADS. So 230 * 1.414 is between 325 and 326 volts, well within the range of this solid state relay (with almost 75V safety margin...). 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. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. My heat bed is running on AC and the relay is in the primary of the step down transformer I'm using. SparkFun Qwiic Quad Solid State Relay Kit. Reminds me of the write only memory or the batteryless solar lamp ! Hi, as stated in the datasheet, it mentioned it has high isolation voltage between input and output. 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. SparkFun Beefcake Relay Control Kit (Ver. Thus the peak value of the mains voltage in the USA is about 120 × √2, or about 170 volts. about 2 years ago This S108T02 is the zero crossing version ... the S108T01 is the non zero crossing version. Will you comment then on who or what is right for RMS 240 Volts ? (I'm glad I bought two, because I fried my first one.. first thing I looked for was if the device would wait to switch at zero crossing. about 5 years ago verified purchaser, I used this item to build a controller for my woodworking shop vacuum. It is not clear from either the datasheet nor from the SFE description whether this is an auto-zero-cross switching SSR, or if it is a phase-angle switching version? Not like in case of soldering stations you carry, where the voltage info is just barely mentioned somewhere within the description. 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. by Member #1111055 .... as noted below you can just design a mosfet circuit for these smallish loads but if you really need isolation here you go. 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. As I said, so far so good. If i could post a pic here of the burnt wood and melted housings, I would. 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. verified purchaser. 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'm putting them in fluorescent ceiling light fixtures so that when the projection screen is lowered the lights go off. The load being switched is a 4800W immersion heater at 240V. A bit late perhaps, but I found it here: https://devhub.io/zh/repos/wmacevoy-ACZCPWM. Solid state relays have several advantages over mechanical relays. You will learn how to add an on button that will provide power to your project for an amount of time and then turn off again. This relay works as advertised, is completely silent and runs cool to the touch. 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? 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. This is the smallest sold state relay I found and it is very nice and easy to install.. about 5 years ago A solid state relay (SSR) is just what it sounds like; an IC that acts like a mechanical relay. The board features two 25A/250VAC solid state 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. The 3.3VDC output from the Photon activates the relay every time and the Particle cloud is easy to use and monitor. I don't know where you get your math from, but it's definitely not the same one the rest of the world uses. There are advantages and disadvantages either way, but we need to know which it is to properly identify what it is suitable for? by Member #536848 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. about 6 years ago Mouser offers inventory, pricing, & datasheets for SparkFun Electronics Accessories SparkFun Accessories. See all skill levels. I've used this with 5V DC from Arduino to switch on/off a light at 240 VAC and (separately) an irrigation system at around 30 VAC. We love it so much we've designed the SparkFun Qwiic Quad Solid State Relay Kit. TL;DR you cannot reliably trigger this with a 3.3V GPIO (it will be modulated or not trigger at all). Just one would do for controlling a 240vac device. Why is this necessary? See all skill levels. 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 would also love a DC version, I do fun stuff with the Rebel LEDs. Connect it between your LED and ground, and send logic level high to the gate and voila, your led turns on. As a DC load does no such thing, this device can switch it on - but not off. You may need to provide your own basic tools like a screwdriver, hammer or scissors. by Member #718397 The actual download link still points towards his GitHub repo, which is no longer present. about 2 years ago We wanted to let you know that SparkFun will be closed on Friday, 1/1/2021 in observance of the New Year's Day holiday. Is that an acceptable use for this thing, or should I use a relay? verified purchaser, about 5 years ago We bought 35 pieces but haven't had a chance yet to put them to work. 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. To control 240V, you would need two. about 5 years ago Our MakerSpace has a classroom where the only light switch is at the opposite end of the room from the entry. I just don't know if there is a transistor capable of switching a 120 volt load with a 5 vault switch. verified purchaser. The Rebel LEDs are something that must be witnessed in person to understand how bright they are, a photo doesn't do them justice. On pg6, fig2, do I read up my ambient temp to the desired A, then find the closest curve above it? ... Updating footprint for Dual Solid State Relay, reversing pins. SparkFun-Displays.lbr. verified purchaser, about 2 years ago verified purchaser. I always have a huge amount of trouble finding SSRs. I have to control the same CFL in two modes, one is using an AC switch and the other is using this relay. So your best bet is a small microcontroller, sample the voltage with one of the ADC pins, and turn on the desired relays based on the voltage. by Member #1373653 Hey, I was thinking of starting a Christmas project in which several light strands are timed to music. (You can also get MOSFET-based easy to use "solid-state relay" devices for DC use.) about 4 years ago * The kit is substantially smaller. For technical questions please check out our Forums. Power tools or custom parts are not required. Activates well with only 3vdc current, and handles the large AC current fantastically, about 5 years ago verified purchaser, I have it driving two stove eyes in a homemade oven. It handles it with no problems and no heat even without a heatsink, about 5 years ago verified purchaser. 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. 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. Wired this into an outlet box to turn on outlets using the 12V trigger from my surround sound receiver. You can export the part and footprint using the standard eagle ULP. * Expense. by Member #811852 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. verified purchaser. Am I reading the datasheet right, it takes 1.4V to switch the load? I don't want main voltage anywhere near the rest of circuit or my body. However, if you are looking for solutions to technical questions please see our Technical Assistance page. Anyone have an Eagle library for this yet? b) The input side is basically just a LED. Me and Mrs. Jonesing. 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. verified purchaser. If yes, how? about 2 years ago The hole size on the TO-220 sink (https://www.sparkfun.com/products/121) looks compatible. verified purchaser, about 2 years ago Thanks for the example layout. verified purchaser, about 3 years ago * Heatsink is pretty much optional. It is NO. verified purchaser. Per Unit $9.95. verified purchaser, I lost both due to error in circuit. We've done it before at work. They make these nifty packaged up devices that don't need a circuitboard, trying to figure out the resistances needed, etc. For remote switching of non-trivial AC applications, this relay can't be beat. Note that it won't actually be strictly 'Open Circuit', even with one in each phase. https://www.sparkfun.com/products/10684 So whoever said you don't need a heat sink in the other reviews...think again! Happy New Year from all of us at SparkFun! Anyone ever used these to switch 24vac HVAC lines in a thermostat? by meljr See images. One such advantage is that they can be switched by a much lower voltage and at a much lower current than most mechanical relays. 2.0) KIT-13815 . 5 In Stock: 1: $150.00: Buy. by Member #700219 I'm using this relay to switch the 120v power to the mercury vapor street light. 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. I needed an easy way to disconnect RV power after I had already climbed into my bunk. 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. I thought leakage currents are usually in uA for good SSRs?? But when I'm dealing with 110VAC, don't think a breadboard would be capable of handling a lot of power. by ijeffsc Be sure to check out the datasheet (p.6 Fig.2) for more info. Will this work to relay DC? 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. Mounting is easy and the terminals are full size so you can simply split right off the power cord very easily with the peace of mind that the connections will remain solid. about 2 years ago 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. So, basically, if you've got an Arduino or whatever, you just drive it like it's a LED. Just because it's essentially just a MOSFET, doesn't mean someone wants to mess with that aspect of things- sometimes they just want a solid-state switch for a design. SparkFun Forums . I didn't measure it, but with an LED lamp attached, it could charge up and flash the lamp every 5 sec when OFF. A a footnote, Sparkfun should pay a little more attention to the customers from 230V parts of the world. by Member #107234 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. Solid State Relay? CF This kit allows you to assemble up to four of these solid state relays on a single PCB and control them all via I 2 C from your favorite microcontroller. Jul 16, 2020. Sorry I can't buy more to finish project as out of stock with no date expected to be available. 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: Creative Commons Using a toaster oven that draws about 10 amps AC at 120 volts. AC load only! In that particular case, nothing in the controller circuit got damaged, but I did measure several megohms resistance between the control inputs and the AC inputs (and shorted AC output) after meltdown. I was concerned about heat because I mounted the relay inside he machine, but I have had no problems. I was planning on using one with and ESP8266 to PID control a crock pot (as a Sous Vide cooker) using my cellphone as the user interface. I might add 240 Volts times square root of 2 equals 340 volts but the peak to peak is twice that or 679 Volts --80 volts over the rating? Bummer to hear that it doesn't work with a 3.3V input, I wish I had seen your post before I ordered one. Mind the leakage current, if that sort of thing matters to your project. What you're looking for is an N-Channel Logic Level Power Mosfet. Some 3.3V boards, like LinkIt ONE, will only supply 3mA from a … about 3 years ago Just wish I knew what kind of amperage it could take at 120 volts. Single T about 9 months ago IMO don't go 8 amps with these, stay below 5 amps (use a heat sink above 2 amps). 3) How do I figure the required size of heatsink? The one real bummer was me connecting the control lines to the holes spaced for the AC input on the first revision of the PCB (a very well learned $30 mistake), I should have probably noticed it, but their are no markings in the SF Eagle library for this part, it just shows the outline, so you have to go by the hole spacing, subtle if you aren't expecting it. A solid state relay (SSR) allows you to control high-curent AC loads from lower voltage DC control circuitry. 2) Any decent tutorials on snubber circuits? 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. If you have an order or shipping question please refer to our Customer Support page. 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 … 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). 1) On page 9 of the datasheet (showing the standard circuit), a protection diode is on the DC controller side. by Member #677330 SparkFun: I am using the relays so the pressure switch contacts will last longer. Please keep in mind that any orders placed after 2:00 pm MT on 12/31/2019 will not be processed until we resume normal business hours at 9 am MT on Monday 1/4/2021. by Member #871915 My sous vide cooker is about 1200W, and when the full load is going through the SSR as it initially brings things up to temp, it still isn't hot to the touch. * Much more limited range on the control voltage. Why do you need one? Smart garden sprinkler controller using Windows 10 IoT on a Raspberry Pi with sensors and smarts provided by the Internet. I generally calculate the load current and multiply that by two, and then use a heat sink anyway. Or at least bolt them to an alum plate. by Member #871262 Removing the thermals, or increasing the size of the pour to get 4 spokes per side would be a good idea. This particular SSR can switch current loads of up to 40A with a 3-32V DC input and a zero cross trigger control method. verified purchaser. The application is a cheap PID temperature controller maintaining a water tank temperature as part of a hydronic heating system. It also says the maximum zero crossing voltage is 35V, so at 24V it may not "see" the sero crossing and never turn on. Don't even get warm with 100 bulb strands. : 1 Mult. I was able to add an AC switching element to my board very quickly. To calculate the value for the resistor connected to Vcc (R1 in the diagram), use V=IR. May or may not be worth keeping in mind for your circuit. Pros/Cons over the PowerSwitch Tail kit? My doubt is, when the switch turn on, AC terminals of relay get short circuited. It is very easy to integrate this into a project since Sparkfun provides the EAGLE footprint and sample circuits. by Member #171000 verified purchaser, about 3 years ago A decent solid start relay for sale? Happy New Year from all of us at SparkFun! Used this in my very first Arduino project and was quite satisfied. Hooray! Sewing may be required, but only with included patterns. about 6 years ago A similar calculation indicates that the peak-to-peak mains voltage in Europe is about 650 volts. Any word as to when these will be back in stock? This is a robust device, at a good price. Of course, I discovered this a little later than I'd have liked to. Really helps with noise problems that way. by Member #391646 The screw terminals work nicely with either bare wire or spade connecters.
