I am using the relays so the pressure switch contacts will last longer. 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. IMO don't go 8 amps with these, stay below 5 amps (use a heat sink above 2 amps). There's no mention of a heatsink being required in the description. Also, because there’s no moving contacts, solid state relays can be switched much faster and for much longer periods without wearing out. ... COM-13015 Solid State Relay 40000mA 32V DC-IN 4-Pin. Google the U2008 IC instead. Worse than that, since the triggering element is zero crossing, it would not switch on until ... power is removed ! 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. SparkFun: Pricing and Availability on millions of electronic components from Digi-Key Electronics. $1.95. Anyone know of a good alternative to one of these. 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. Just saying.

Picked up several of these when I was planning my home automation system. 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. www.omron.com.au/service_support/FAQ/FAQ02155/index.asp. Wish List! first thing I looked for was if the device would wait to switch at zero crossing. The load being switched is a 4800W immersion heater at 240V. Without a heat sink, you shouldn't operate at >2.5A at room temperature. They make these nifty packaged up devices that don't need a circuitboard, trying to figure out the resistances needed, etc. about 5 years ago Thats what it is! Does that mean it is well isolated so I don't have to set up a protection for my raspberry pi when I connecting them together ( in case of damaging my raspi) ? about 2 years ago 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. Been using it with 120v 60hz and now 50hz without issues. https://www.sparkfun.com/products/10684 If using for intermittent use (pump, fan, etc), you could probably get away with open air. and handle quite a bit of amperage. Now I can digitally control my brewing mash temps! AVR Microcontrollers. 5 In Stock: 1: $150.00: Buy. I don't think resistors come in 125ohms, but 120ohm or 130ohm should work just fine. verified purchaser. Sorry, could not get the formatting to work and gave up. Favorited Favorite 29. Don't even get warm with 100 bulb strands. One such advantage is that they can be switched by a much lower voltage and at a much lower current than most mechanical relays. New Product. Will you comment then on who or what is right for RMS 240 Volts ? verified purchaser. Do I need transistor? This S108T02 is the zero crossing version ... the S108T01 is the non zero crossing version. We welcome your comments and suggestions below. 2) While the current rating is 8A, you'll need a heatsink to operate this high. Need a breakout board like the Relay Control PCB. 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). 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. but I bought 2 more. DC SSR is essentially just a MOSFET... Google 'MOSFET as a switch'. Solid State Relay. 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. If you are in a country where one side of the 240V is ground-referenced, then you would only need one. images are CC BY 2.0. On pg6, fig2, do I read up my ambient temp to the desired A, then find the closest curve above it? Remember to always read the datasheet when uncertain. Hey, I was thinking of starting a Christmas project in which several light strands are timed to music. 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. THIS PART CANNOT SWITCH DC LOADS. They allow you to control high-voltage AC loads from lower voltage DC control circuitry. Pros/Cons? The hole size on the TO-220 sink (https://www.sparkfun.com/products/121) looks compatible. 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. adding mounting hole, pink alphanumeric display. after all as you say if either is disconnected its an open circuit and thus not working. 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? This particular SSR can switch current loads of up to 40A with a 3-32V DC input and a zero cross trigger control method. I want to control a CFL using this relay. If you have an order or shipping question please refer to our Customer Support page.

We bought 35 pieces but haven't had a chance yet to put them to work. If the load doesn't use the neutral, you could get away with one, but that would be against NEC and a safety hazard as the load would still be live with respect to ground or neutral when turned off. I need a few for an automotive project, relaying 12V with 20 and 30 amp loads. http://www.opto22.com/site/pr_details.aspx?cid=4&item=DC60S5. verified purchaser. The solid state relay can be controlled with 3V, so is suitable for the 3.3V arduino boards. I'm just throwing in a vote for carrying a DC SSR as well. SparkFun Forums . But I was thinking about controlling the input at a high frequency, say 1000 kHz, so may be that won't be a problem? This switch has worked perfectly for two weeks. Note that it won't actually be strictly 'Open Circuit', even with one in each phase. Why is this necessary? I use these with no heat sink for loads under 2 amps. One thing I always look for, though, is the "zero cross" switch. Contribute to sparkfun/SparkFun-Eagle-Libraries development by creating an account on GitHub. I will be using these for all my AC voltage projects. 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. I have the relays mounted on a heat sink appropriate for 15 watt heat dissipation. And if you're adhering, make SURE it's a thermal adhesive like Artic Alumina. 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. It handles it with no problems and no heat even without a heatsink, about 5 years ago It needed closer to 5v to activate. verified purchaser. Couldn’t ask for better. But when I'm dealing with 110VAC, don't think a breadboard would be capable of handling a lot of power. by ijeffsc Also, because there's no moving contacts, solid state relays can be switched much faster and for much longer periods without wearing out. The datasheet shows a leakage current of 3mA. * Much more limited range on the control voltage. SparkFun's Public Eagle PCB Footprints. 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. The kit is more than twice the cost, and this one does not require me to build it. For technical questions please check out our Forums. by Member #339294 by Member #536475 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 :-). the triac shorts. You do not expect to run much with one this small, so you do not push it. 20x20cm! 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. 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. 2) Any decent tutorials on snubber circuits? Mouser Part # 474-COM-16810. I am running a fan with one at 230V 1.7A (>10A for very few milliseconds during startup). by Member #700219 What would be the main difference between using this and say the KIT-10684 Solid State Relay Kit from SFE? Favorited Favorite 23. A a footnote, Sparkfun should pay a little more attention to the customers from 230V parts of the world. By smdFan - Mon Mar 23, 2009 3:35 pm - Mon Mar 23, 2009 3:35 pm #69057. Do these "Al plates" described need cooling fins, or is just a smooth lunk of metal sufficient? I'll second that! Just wish I knew what kind of amperage it could take at 120 volts. Why do you need one? Activates well with only 3vdc current, and handles the large AC current fantastically, about 5 years ago More importantly though, the datasheet does not specify whether the switched voltage is ac or dc. To allow for faster and quieter switching of the load, this board uses solid state relays instead of electromechanical relays. At one point I would like them to blink very fast; is there any danger to switching on and off 120V AC at high speeds (like 10 times per second)? Mine are running at less then 20amps and work very nicely. verified purchaser. The force sensor is going to measure air coming out of a sub woofer. The 3.3VDC output from the Photon activates the relay every time and the Particle cloud is easy to use and monitor. about 5 years ago 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. Using a toaster oven that draws about 10 amps AC at 120 volts. Commanding the device on and off 10 times a second is not a problem at all. Mouser offers inventory, pricing, & datasheets for SparkFun Electronics Accessories SparkFun Accessories. What you're looking for is an N-Channel Logic Level Power Mosfet. If you're putting 40A into it, yes, you will need a heatsink. verified purchaser, I used this item to build a controller for my woodworking shop vacuum. verified purchaser. about 5 years ago 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. 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 screw terminals work nicely with either bare wire or spade connecters. .... as noted below you can just design a mosfet circuit for these smallish loads but if you really need isolation here you go. I have to control the same CFL in two modes, one is using an AC switch and the other is using this relay. If you're living in the 230V part of the world, you should definitely go for a 600V version (S208T02, S202S02F). verified purchaser, I lost both due to error in circuit. Agreed! by Member #391646 Check the example layout we linked to. However, if you are looking for solutions to technical questions please see our Technical Assistance page. 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. By the way, these are listed as obsolete by Digi-Key - they list the S202S02F instead. Sorry I can't buy more to finish project as out of stock with no date expected to be available. I had thought about this. I'm also curious about that diode. They failed in the "on" state which was disconcerting. by chipmc 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. 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. When the light comes on it pulls several amps as the arc starts, then the current demand decreases to about 1.5 amps. It works well, and is silent. 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. by Member #710419 verified purchaser. Archive. Aug 20, 2020. It worked perfectly as soon as I wired it up. 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. 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. 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. Thank you for your continued support. The peak-to-peak voltage, being twice this, is about 340 volts. May or may not be worth keeping in mind for your circuit. in its parameters and connection diagrams your questions may already been answered. A similar calculation indicates that the peak-to-peak mains voltage in Europe is about 650 volts. This is a robust device, at a good price. Use as said above like an LED on the DC side . A solid state relay (SSR) allows you to control high-curent AC loads from lower voltage DC control circuitry. New Product. by Member #171000 about 5 years ago verified purchaser, about 5 years ago 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. Buy a version with a brand name, like Omega and follow their instructions, which say to use a sink. When these are used with higher power devices, a heat sink is recommended. I know that the coil versions are specific to AC but what about this one? Also, you may need a power supply that?s greater than 12V or more than 1A worth of current. CF by Member #795668 Per Unit SparkFun Electronics Solid State Relay COM-00100 Power Relay … Mind the leakage current, if that sort of thing matters to your project. (2 Amp?). the tilde on the ic package labels it for ac, but what would the dc limits be, if it will even accept dc? However, it wouldn't actually activate from the 3.3v digital pins on my Arduino. Why is that in the sample circuit? 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. If it requires power, you need to know how much, what all the pins do, and how to hook it up. verified purchaser, about 2 years ago The input is easy to switch with an Arduino or other 5V microcontroller output, to control e.g. 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. You may need to reference datasheets, schematics, and know the ins and outs of electronics. Is not the optical isolation sufficient protection? This is a great one at a great price, btw, so thank you!!! Maybe works for 40A but for my light load it has too much leakage current and the load partly runs when OFF. verified purchaser, about 3 years ago COM-13015 SparkFun SparkFun Accessories Solid State Relay - 40A (3-32V DC Input) datasheet, inventory, & pricing. 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 A couple of comments to help people use these: Will this damage the relay or is there any chances for other damages ? 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. Jul 16, 2020. I just purchased 3 more just to hold in case I have another use for them. Thank you for your continued support. I was concerned about heat because I mounted the relay inside he machine, but I have had no problems. Also easy to wire up. I don't know where you get your math from, but it's definitely not the same one the rest of the world uses. The 40A SSR Relay allows you to control high-curent AC loads from lower voltage DC control circuitry. 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. And it works! by Ian R. Been using it a couple weeks now, and it is functioning perfectly. verified purchaser. That is, switch and relay should be connected in parallel like a LOGICAL OR GATE. The kit is rated for 8 amps this is 40 amps, although that requires a heat-sink. SparkFun-Displays.lbr. Get free design tools and engineering support. Not like in case of soldering stations you carry, where the voltage info is just barely mentioned somewhere within the description.

", So these are not good for 240 Volts like we have in Australia as the peak to peak voltage can be 650 Volts. (It's an IR LED.) Part # COM-16810. about 5 years ago I didn't measure it, but with an LED lamp attached, it could charge up and flash the lamp every 5 sec when OFF. They make Automotive and other DC switched versions of these devices. Although they didn't burn up they failed on for my application in hours or days. I have sence switched to esp8266 modules and it works with them as well. See all skill levels. about 4 years ago by Member #489595 That would, it seems to me, "neck down" the effective copper width to carry the current to something like 80 mil (only two spokes per pour, per side connect to the pins on the relay). The new form factor (P/N S202S02F) fits a TO-220 heat sink perfectly, whereas this older design not as well. 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. Am I reading the datasheet right, it takes 1.4V to switch the load? If it requires power, you need to know how much, what all the pins do, and how to hook it up. SparkFun Electronics SparkFun Accessories are available at Mouser Electronics. I should've waited for these I guess. 2.5V / 20mA gives a resistor value of 125ohms. Mouser Part # 474-COM-16810.

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). Used my one spare to check circuit changes and works great. Just check the data sheet before selecting it--it says 3mA leakage. It's worth noting it's 400V peak, not RMS. Learn More. 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. DEV-14150 – Electromechanical Relay Raspberry Pi Platform Evaluation Expansion Board from SparkFun Electronics. 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? 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. by Member #169074 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.
