Ordered one of these to use for a Xmas light display (run of an Arduino) and while they are easy to hook up (with the help of Google... as it doesn't come with any kind of documentation) I guess its hit or miss whether you get a good board or not. The first one I tried had problems with the #1 relay... depending on the programing sequence I wrote. Sometimes relay #1 wouldn't click on (even though the light was on) until relay #2 was called too. I ordered a second board and that board worked perfect with the same programing. They are cheap enough so it might be worth getting more than one if your project is an important one. Over all I am happy with the board but we'll see how long it runs for.12-24-22 Update - I'm not sure what working temperatures these are rated for but... my board stopped working on a 10°F day. It is sealed in a water proof box but I had to bring them back inside to warm up and it started working again... Just something to think about when planing your project.

Connected to CAI WebControl PLC using dedicated 5 VDC supply connected to 12 VDC Webcontrol power. Relays operate on active low input signal (0 VDC). Use inverse logic in WebControl for fail-safe operation i.e. relay contacts open when power is OFF. Relays are controlling 24VAC irrigation valves with no contact protection applied. No problems after a few days of operation. Fingers crossed!

Very impressive ratings for the relays in terms of VAC and VDC and rather high amps. I cant yet answer how many cycles they will last-- if they last 10 000 closures, then they are perhaps not great, but if they last 100k, impressive. Also, they have excellent board quality, easy connections. All round, excellent value.

These are wonderful and a great value. These have both optical and magnetic isolation, providing a lot of protection to the inputs from electrical faults on the outputs. They work well with 3.3V and 5V logic (RasPi, Teensy, Arduino, ...), requiring little current drive. Very breadboard-friendly if you use a simple M/F jumper wire.They have indicator LEDs that can save you hours of problem-determination time, aid classroom demonstrations and reassure you things are working as expected. They're red, so someone might confuse them with error LEDs. The contacts have fairly low bounce and quick switch-over time.They have 3 terminals per SPDT relay, but they are soldered to the board, not on a connector. This is the only drawback I can find with this product. If you twist too hard, you can ruin the terminal. Fortunately it's a common header and easy to resolder.

Experience: Software engineer, learning electronics with my Arduino. My dad is an EE talked me through all current measurements.SETUP:- Connect arduino powersupply 5v to VCC- Connect arduino Digital ground to ground- Connect arduino digital output to any IN1-IN8- You're in business!CURRENT:I connected my meter in series and found I was drawing 64mA across the Arduino 5v power supply and 1.9mA across the Arduino output pin.I flipped it over and measured 7100ohms across the coil, meaning the coil is drawing 0.7mA at 5v.These numbers honestly seem a little low to me - e.g. I expected more like 19mA across the output, but 64mA across the power supply seems very reasonable with all eight relays drawing 400mA per the spec.Note: Arduino max power supply voltage is 500mA on USB, so you're good there too.PROS:- This won't blow up your Arduino.- I didn't realize this model had LEDs. I looked at the 4 relay model and the LEDs are bigger, but these are smaller and work great.- LED's in the circuit act as diodes. My dad told me when the field collapses on a DC coil it generates a negative voltage. If you don't have a diode in the way you could burn up your output transistor.- This has NC (Normal Closed) and NO (Normal Open) contacts on the high voltage side. So if you want your lights ON or OFF by default you can do that. It has a nice diagram on the board showing how the high voltage contacts are laid out.- Price- 4 mounting holes on the board if you need to bolt it to something!- Lot's of fun - you should buy one!CONS:- N/AOTHER:- The header PINs are really nice, but I only have male breadboard jumpers and need to buy some male-female jumpers from radio shack before I can hook this baby up to my xMas light setup!!

I purchased this relay to work with my Arduino to experiment with running indoor Christmas lights to music. As most say, the documentation is limited, but enough information is on-line that it is fairly easy to get them running. I was switching on/off several electrical devices within about 30 minutes.Not a fault of the product, but they are very noisy, so for the "Christmas lights to music" purpose I had to place it in a box with sound proofing material. Most relays click when they switch, so when you have 8 of them banging away to music it's pretty loud. My conclusion is that using them for this purpose will wear out the relays pretty soon. If you're looking for relays for rapid switching, I'd suggest the solid state version, although they are lower power rating. My lights are 120 volt so I went mechanical.The product is very solid, assembled well, and works exactly as advertised. I'll probably re-purpose the product for controlling other high voltage items in the house. Based on my experience so far, I'd say it is a perfect device for home automation projects.
