A a footnote, Sparkfun should pay a little more attention to the customers from 230V parts of the world. Mind the leakage current, if that sort of thing matters to your project. Hello all, I am designing a light show to be powered based upon a bendable force sensor sending me and int 0-1024 based on how much the sensor is bending. 5 In Stock: 1: $150.00: Buy. If it requires power, you need to know how much, what all the pins do, and how to hook it up. 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. SparkFun Forums . Part # COM-16810. Hey, I was thinking of starting a Christmas project in which several light strands are timed to music. Keep in mind though, that LED's require a constant current power source, so if your LED(s) didn't come with a driver, you'll need a way to limit current else they'll burn themselves out. Buy COM-13015 with extended same day shipping times. I assembled this on a custom designed PCB with the relay, some heavy duty terminal blocks and pinouts for a TMP102 temp sensor, all this controlled by a Particle Photon. about 6 years ago I used an Arduino Nano with one of these to build a cycle timer. 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. My doubt is, when the switch turn on, AC terminals of relay get short circuited. by Member #811852 See all skill levels. Our MakerSpace has a classroom where the only light switch is at the opposite end of the room from the entry. 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. about 2 years ago Also, because there's no moving contacts, solid state relays can be switched much faster and for much longer periods without wearing out. Connect it between your LED and ground, and send logic level high to the gate and voila, your led turns on. And it works! 2.5V / 20mA gives a resistor value of 125ohms. Thats what it is! 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 :-). Mouser offers inventory, pricing, & datasheets for SparkFun Electronics Accessories SparkFun Accessories. 2) While the current rating is 8A, you'll need a heatsink to operate this high. Mon-Fri, 9am to 12pm and That's barely enough to carry 8A with 2.5oz copper. I don't want main voltage anywhere near the rest of circuit or my body. This is a great one at a great price, btw, so thank you!!! I was concerned about heat because I mounted the relay inside he machine, but I have had no problems. Sewing may be required, but only with included patterns. We love our Solid State Relay - 40A. I always have a huge amount of trouble finding SSRs. Just think of the possibilities. I should've waited for these I guess. Overall the project works well, though having a heatsink is mandatory for any loads over maybe 0.5A, anything after that it gets uncomfortably warm (and decreases it's lifetime), at my demand of 160W(1.33A) things get hot enough to make me uncomfortable, the data sheet tells you this same story but you have to read carefully to understand the devices limits, if you try to pull 8A you will need some serious heatsinking or you'll let the magic smoke out, nothing to mess around with when working with 120VAC. Of course, I discovered this a little later than I'd have liked to. If you're putting 40A into it, yes, you will need a heatsink. The one I have in my espresso machine is inside the machine's case, and routinely sees 220 deg F; the heat so far has not affected functionality at all. DC SSR is essentially just a MOSFET... Google 'MOSFET as a switch'. BTW is the heat sink tab isolated from the logic input ground (it BETTER be isolated from the power line!)? I just purchased 3 more just to hold in case I have another use for them. 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. The big difference is the current rating. about 5 years ago The peak-to-peak voltage, being twice this, is about 340 volts. It's worth noting it's 400V peak, not RMS. verified purchaser. SparkFun: SparkFun Accessories SparkFun Qwiic Dual Solid State Relay. Why do you need one? verified purchaser, about 3 years ago $1.95. http://www.instructables.com/id/The-inner-workings-of-Counterfeit-FOTEK-SSRs/[/url]. 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. * Expense. I would also love a DC version, I do fun stuff with the Rebel LEDs. What I liked was that it was able to work with the raspberry pi at 3.3v without a problem. As a DC load does no such thing, this device can switch it on - but not off. My heat bed is running on AC and the relay is in the primary of the step down transformer I'm using. Anyone know of a good alternative to one of these. Thanks! It uses a Sharp SSR module and can switch 125VAC at 8A (AC only - not 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. Teehee. by Member #718397 Any solid state relay that's controlling more than a few watts will need a heatsink. Sorry, could not get the formatting to work and gave up. CF It needed closer to 5v to activate. verified purchaser. (2 Amp?). verified purchaser. Can I use it from raspberrypi (3.3v) to drive a DC circuit at 12v? Basically, there are 2 legs of 120V offset by 180°. This is a robust device, at a good price. See all skill levels. Used this in my very first Arduino project and was quite satisfied. Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. SparkFun Qwiic Quad Solid State Relay Kit. We'll start spinning them today, available soon. Your post implies you've used these before. 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. I've hooked these up to Raspberry PIs and ESP8266's no problem. and handle quite a bit of amperage. Was able to switch mains AC power with an Arduino UNO using PWM. Mon-Fri, 9am to 12pm and by Member #677330 Hi there! It's not like an EM relay that you need diodes and such... you only need a transistor. This SSR is nicely 0.1" spaced and very breadboard compatible. It almost looks like a bridge rectifier offhand :) what with the pin labels. about 2 years ago To calculate the value for the resistor connected to Vcc (R1 in the diagram), use V=IR. verified purchaser. SparkFun Beefcake Relay Control Kit (Ver. They make these nifty packaged up devices that don't need a circuitboard, trying to figure out the resistances needed, etc. verified purchaser. If you try to run 2 off the Arduino with only the USB it can't quite power them. So whoever said you don't need a heat sink in the other reviews...think again! This relay works as advertised, is completely silent and runs cool to the touch. Worse than that, since the triggering element is zero crossing, it would not switch on until ... power is removed ! Yes, that it is, but you have to design up the circuit, etc. The 3.3VDC output from the Photon activates the relay every time and the Particle cloud is easy to use and monitor. 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. verified purchaser. about 9 months ago about 5 years ago Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. I had thought about this. Please see all COVID-19 updates here as some shipments may be delayed due to CDC safety and staffing guidelines. I'm using a similar relay to control the heat bed on my 3D printer I'm building. first thing I looked for was if the device would wait to switch at zero crossing. 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. about 2 years ago I have sence switched to esp8266 modules and it works with them as well. replied on March 7, 2016: Weekly product releases, special offers, and more. ... COM-13015 Solid State Relay 40000mA 32V DC-IN 4-Pin. We've done it before at work. verified purchaser. Works every time with Particle Photon IOT. Going to buy two of these tonight, also going to buy a thermocouple and thermocouple breakout. about 3 years ago : 1. The datasheet shows you the recommended heat sink for this product. Been using it with 120v 60hz and now 50hz without issues. about 5 years ago Driven from a raspberry pi. There are advantages and disadvantages either way, but we need to know which it is to properly identify what it is suitable for? 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. Somewhere. Mouser offers inventory, pricing, & datasheets for SparkFun Electronics SparkFun Accessories. If you are in a country where one side of the 240V is ground-referenced, then you would only need one. AVR Microcontrollers. These solid state relays are controlled by a 3-32 DC signal on the input, but the output must be connected to AC. Part # COM-16810. For safety reasons, remember almost all solid state relays have some leakage current when in the off state. 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 thought the same thing when I saw the pic. The 40A SSR Relay allows you to control high-curent AC loads from lower voltage DC control circuitry.
