I'm also curious about that diode. Buy a version with a brand name, like Omega and follow their instructions, which say to use a sink. SparkFun-Displays.lbr. Happy New Year from all of us at SparkFun! New Product. A solid state relay (SSR) allows you to control high-curent AC loads from lower voltage DC control circuitry. thanks. by Member #191965 Connecting it to an ESP8266, and a HDT22, I was easily able to make my own 'Nest' device to control the power to my AC unit for about a year now. Removing the thermals, or increasing the size of the pour to get 4 spokes per side would be a good idea. 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… This unit combined with a micro switch is a perfect solution! I'm just throwing in a vote for carrying a DC SSR as well. It'd be nice to have something in this class of device that did this available (And I'm a bit surprised with the emphasis on robotics SparkFun has that they don't carry such parts in inventory...) Guess I'll be looking elsewhere for that because I need it for a project and I need to be switching about 4-5A at 12V on an often enough basis that I'm needing to worry about contact life on a electromechanical relay. by ROB-24601 September 29, 2020 08:22 Pacific Daylight Time 0 Old forums & topics. The kit is rated for 8 amps this is 40 amps, although that requires a heat-sink. They make these nifty packaged up devices that don't need a circuitboard, trying to figure out the resistances needed, etc. I'm probably still comparing it to the HSR412s I've melted though. 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. https://www.sparkfun.com/products/10684 We welcome your comments and suggestions below.

I originally bought another very similar SSR, also rated for 3~32VDC on the control side. Solid State Relay. 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. A nice solid state relay. As I said, so far so good. The screw terminals work nicely with either bare wire or spade connecters. The data sheet says the minimum load frequency is 47Hz so I assume it is AC only, but I wonder if it would switch a smaller DC load. by Member #445373 Smart garden sprinkler controller using Windows 10 IoT on a Raspberry Pi with sensors and smarts provided by the Internet. replied on March 7, 2016: Weekly product releases, special offers, and more. This SSR is nicely 0.1" spaced and very breadboard compatible. Solid state relays have several advantages over mechanical relays. about 3 years ago I'm putting them in fluorescent ceiling light fixtures so that when the projection screen is lowered the lights go off. However, if you are looking for solutions to technical questions please see our Technical Assistance page. with the sealed design and high amperage capability, I am purchasing more of them to add control over my baseboard heaters next!

Sharp has changed the package for this device, and this particular version Sparkfun is selling is the older, prior design. by ijeffsc However, your handling of our order and shipping was 5 star! For those curious about "failure modes", my experience is that when they fail (due to overheating), they fail in the "closed" (ON) position -- i.e. Using a trinket to control a 175w street light, Part works well, Eagle library silkscreen needs work, [Datasheet](http://cdn.sparkfun.com/datasheets/Components/General IC/S108,208T02 Series.pdf), [Example Layout](http://cdn.sparkfun.com/datasheets/Components/General IC/SSR-Board-v10.zip). Theoretically, it should work with just one, as there would be an open circuit unless the relay was closed. about 9 months ago about 5 years ago Any word as to when these will be back in stock? Yes, that it is, but you have to design up the circuit, etc. Any solid state relay that's controlling more than a few watts will need a heatsink. by Member #871915 by Member #1373653 SparkFun Qwiic Quad Solid State Relay Kit. The relays are a good value and work well. Just think of the possibilities. by Member #623360 about 2 years ago Mind the leakage current, if that sort of thing matters to your project. SparkFun Forums . 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? SparkFun Accessories SparkFun Qwiic Dual Solid State Relay Enlarge Mfr. Pros/Cons? Just wish I knew what kind of amperage it could take at 120 volts. At 40A load, that's 64 watt of power you need to dissipate via heat sink! Whether it's for assembling a kit, hacking an enclosure, or creating your own parts; the DIY skill is all about knowing how to use tools and the techniques associated with them. You may need to provide your own basic tools like a screwdriver, hammer or scissors. But I'm not aware of that. The application is a cheap PID temperature controller maintaining a water tank temperature as part of a hydronic heating system. I need a few for an automotive project, relaying 12V with 20 and 30 amp loads. by Member #377250 Just make sure to have a DC power supply hooked up to the Arduino and it works great. verified purchaser.

If you're putting 40A into it, yes, you will need a heatsink. #69057. about 5 years ago 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. Aug 20, 2020. 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. Wish List! Also, you may need a power supply that?s greater than 12V or more than 1A worth of current. about 2 years ago SparkFun: These work great but suggest a heatsink or at least monitor the temperature for loads of more than a couple hundred watts. Any idea what the leakage current of the triac is? Thus the peak value of the mains voltage in the USA is about 120 × √2, or about 170 volts. verified purchaser. Has been working perfectly! But a 3.7V power supply should be plenty. 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. DEV-14150 – Electromechanical Relay Raspberry Pi Platform Evaluation Expansion Board from SparkFun Electronics. I have a glass kiln with temperature control within 0.1 degrees in 1000 degrees. It's easy to put a radiator on the back - there's a nice metal plate, just add a couple mounting screws and some thermal paste - but I haven't needed to do so. by Member #630068 However, it wouldn't actually activate from the 3.3v digital pins on my Arduino. Used my one spare to check circuit changes and works great. ACZCPWM makes accurately controlling these possible (and easy). by Member #107234 400V peak is only ~280V RMS which leaves a quite low safety margin for continuous usage under 230V. www.omron.com.au/service_support/FAQ/FAQ02155/index.asp. SparkFun Beefcake Relay Control Kit (Ver. by Member #169074 Home. I had thought about this. We'll start spinning them today, available soon. More importantly though, the datasheet does not specify whether the switched voltage is ac or dc. Was able to switch mains AC power with an Arduino UNO using PWM. by Member #1392 The datasheet shows you the recommended heat sink for this product. Going to buy two of these tonight, also going to buy a thermocouple and thermocouple breakout. See images. "Just a MOSFET" doesn't get you isolation combined with fairly high switch currents without a lot of thought and design that people like Cydom or Opto-22 put into making these things. Instructions will be included and easy to follow. Anyone ever used these to switch 24vac HVAC lines in a thermostat? : 1 Mult. Couldn’t ask for better. 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. about 5 years ago Thank you for your continued support. For remote switching of non-trivial AC applications, this relay can't be beat. Learn More. I am planning on designing a Photon controlled toaster oven reflow. Note that it also requires a driver circuit and the external wire connections are the same as the relay board. But with proper few external elements you can control your mains load with a PWM output - how cool is that! 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. Bought this relay to control an espresso machine heating element. If you are in a country where one side of the 240V is ground-referenced, then you would only need one. I just purchased 3 more just to hold in case I have another use for them. Crap. 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. SparkFun: SparkFun Accessories SparkFun Qwiic Dual Solid State Relay. For safety reasons, remember almost all solid state relays have some leakage current when in the off state. Worse than that, since the triggering element is zero crossing, it would not switch on until ... power is removed ! 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. This unit is sturdy and built really well. Anyone have an Eagle library for this yet? Is that a typo? verified purchaser. about 2 years ago You ship globally and have customers all around the world (me included) so the information on the mains voltage should scream at you in bold red font in the relevant product descriptions. SparkFun's Public Eagle PCB Footprints. For switching mains power, this doesn't sound safe even if it's in the off position. I don't want connections shaking lose. When these are used with higher power devices, a heat sink is recommended. verified purchaser, I have it driving two stove eyes in a homemade oven. Our MakerSpace has a classroom where the only light switch is at the opposite end of the room from the entry. Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Also, because there’s no moving contacts, solid state relays can be switched much faster and for much longer periods without wearing out. Every SSR that I've found online at this current level ( for a reflow oven ) requires a heat sink. (besides SSR). 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. This particular SSR can switch current loads of up to 40A with a 3-32V DC input and a zero cross trigger control method. Per Unit $9.95. 5 In Stock: 1: $150.00: Buy.

Using it to switch 150 watt resistive load - rather tame for the 8 amp rating so there is no heating issue. about 2 years ago by Member #171000 Note that it won't actually be strictly 'Open Circuit', even with one in each phase. I want to know when SparkFun will start carying the infinite heatsink mentioned in figure 2 of the datasheet. c) If you're wiring up 120 V or 240 V AC line voltage, remember to be careful and sensible and stay safe. Pricing and Availability on millions of electronic components from Digi-Key Electronics. Are there any problems using those, that I'm not seeing? Will this work to relay DC? Is not the optical isolation sufficient protection? 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. Could this be used to switch 100vdc at 300khz with a 10% duty cycle? I was concerned about heat because I mounted the relay inside he machine, but I have had no problems. When the light comes on it pulls several amps as the arc starts, then the current demand decreases to about 1.5 amps. but I bought 2 more. I chalked it up to carbonized plastic. SparkFun Quad Solid-State Relay Kit (Qwiic) – Sparkfun KIT-16833. shopping cart, Creative Commons Maybe works for 40A but for my light load it has too much leakage current and the load partly runs when OFF. Hi, as stated in the datasheet, it mentioned it has high isolation voltage between input and output. 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 PART CANNOT SWITCH DC LOADS. The new form factor (P/N S202S02F) fits a TO-220 heat sink perfectly, whereas this older design not as well. Will this damage the relay or is there any chances for other damages ? 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 … verified purchaser. verified purchaser. verified purchaser, This SSR is suitable to switch with out click sound and high power consumption product like heater, Thank you, about 5 years ago It cycles on/off once a day and stays on for about 10 hours. http://www.opto22.com/site/pr_details.aspx?cid=4&item=DC60S5. It's worth noting it's 400V peak, not RMS. AC load only! by Member #651047 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. Yes, I know, lazy. verified purchaser. the tilde on the ic package labels it for ac, but what would the dc limits be, if it will even accept dc? I don't know where you get your math from, but it's definitely not the same one the rest of the world uses. Because of their usefulness in carrying out power calculations, listed voltages for power outlets, e.g. It uses a Sharp SSR module and can switch 125VAC at 8A (AC only - not DC). It also says the maximum zero crossing voltage is 35V, so at 24V it may not "see" the sero crossing and never turn on. replied on September 18, 2018: Sorry to hear you've had trouble with the solid state relay. The peak-to-peak voltage, being twice this, is about 340 volts. So, I ordered this one. A a footnote, Sparkfun should pay a little more attention to the customers from 230V parts of the world. I've used similar types in the past. by Member #1146265 These solid state relays are controlled by a 3-32 DC signal on the input, but the output must be connected to AC. I've hooked these up to Raspberry PIs and ESP8266's no problem. A similar analysis leads to the analogous equation for sinusoidal voltage: Where IP represents the peak current and VP represents the peak voltage. (2 Amp?). It is NO. I don't think resistors come in 125ohms, but 120ohm or 130ohm should work just fine. 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. Mon-Fri, 9am to 12pm and 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. I've been working on a project with 3 of these and I just accidentally broke the lead on one trying to re-solder it. by Member #536848 RL usually refers to the load, i.e. what you are powering on the A/C side. by Member #536475 Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Datasheet says typical voltage to turn the relay on is 1.2V, and current is 20mA. The purpose of the resistor is to set this current at around 20mA. Part # COM-16810. by Member #383813 Hey, I was thinking of starting a Christmas project in which several light strands are timed to music. This is the smallest sold state relay I found and it is very nice and easy to install.. about 5 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. Do I need transistor? 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). Archive. 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. DC SSR is essentially just a MOSFET... Google 'MOSFET as a switch'. the triac shorts. 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. no muss no fuss. A small low current DC voltage control signal from a microcontroller or CNC controller can be use to control a much larger high current high voltage AC load using an SSR or Solid State Relay. The solid state relay can be controlled with 3V, so is suitable for the 3.3V arduino boards. 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 Ian R. Cons of the kit: 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. Why do you need one? SparkFun Electronics Accessories SparkFun Accessories are available at Mouser Electronics. (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 #398708 Used this in my very first Arduino project and was quite satisfied. .... as noted below you can just design a mosfet circuit for these smallish loads but if you really need isolation here you go. 2) While the current rating is 8A, you'll need a heatsink to operate this high. Fast, free and DDP shipping options available. I have used the relay extensively for two weeks now and have had no issues. verified purchaser, I lost both due to error in circuit. The 3.3VDC output from the Photon activates the relay every time and the Particle cloud is easy to use and monitor. So whoever said you don't need a heat sink in the other reviews...think again! 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. I should've waited for these I guess. first thing I looked for was if the device would wait to switch at zero crossing. verified purchaser. Activates well with only 3vdc current, and handles the large AC current fantastically, about 5 years ago I guess some of it was lost in the Chinese translation.... ). One such advantage is that they can be switched by a much lower voltage and at a much lower current than most mechanical relays. Just saying. a) As others have said, because it's a triac-based device, it can not be used on a DC load. Order today, ships today. Read the derating curves on page 6 of the datasheet or you will let the smoke out. 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? The board features two 25A/250VAC solid state relays that utilize the Zero Cross Trigger method so you can toggle two loads on a 60Hz AC The Rebel LEDs are something that must be witnessed in person to understand how bright they are, a photo doesn't do them justice. verified purchaser, about 3 years ago 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. The type I've used (stone age vintage, but they look the same) in good working order had the heatsink (bottom metal plate) insulated from everything. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current. Forward voltage drop is 1.2 V at 20 mA. I have the relays mounted on a heat sink appropriate for 15 watt heat dissipation. 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. Can I use it from raspberrypi (3.3v) to drive a DC circuit at 12v? about a year ago The data sheet says the minumum "load supply voltage' is 80V. 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. 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. Relay SPDT Sealed COM-00100 . Just a warning to any folks that are planning to purchase this: I've confirmed that this unit doesn't exactly work with 3V, as the datasheet suggests. On pg6, fig2, do I read up my ambient temp to the desired A, then find the closest curve above it? My relay requires at least 12v to trigger so I had to use the RAMPS board mosfet controlled 12v output, using one of these I could have made use of any logic output. For technical questions please check out our Forums. Buy COM-13015 with extended same day shipping times. $1.95. 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. But I was thinking about controlling the input at a high frequency, say 1000 kHz, so may be that won't be a problem? Also easy to wire up. 2. Power tools or custom parts are not required. THESE CANNOT switch 8 Amps without a VERY large heatsink! Me and Mrs. Jonesing. Solid State Relay? 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). * Expense. Teehee. My heat bed is running on AC and the relay is in the primary of the step down transformer I'm using. AVR Atmel. Anyone know of a good alternative to one of these. This is a robust device, at a good price. Please see all COVID-19 updates here as some shipments may be delayed due to CDC safety and staffing guidelines. I ordered one of these as a trial and so far is operating fine after several months of continuous use and a year later. I turn the oven on and off with variable duty cycle on a 1 second cycle time.
