Acxico 1Pcs 3-32V DC 1-Channel SSR Solid State Relay High-Low Trigger 5A 5V 12V for Arduino

I needed this to turn on a sizeable solenoid for some laboratory experiments. It was over kill for the amperage I'm using, but the form factor is nice and I like having the overhead for bigger things. works great To test this you CAN NOT use a multi-meter. This uses semiconductor materials instead of how a mechanical relay just connects a copper circuit. You can trigger it with minimal signal voltage/amperage, but the device you're connecting must draw some current. Otherwise the resistance is too high for a basic multi-meter to pick up using the continuity test function. I'd suggest using it to drive some bigger LEDs as a test if you have some. There is a status light on the board, but it's just nice to verify the thing works before going live.

I paired this solid state relay with an Arduino to drive four fuel injectors during ultrasonic cleaning. Even though I was exceeding the rated current capacity, the relay worked fine as long as I hooked up the injectors one after the other. For those that may hook this up then wonder why it doesn't work, please note that current will only flow in one direction through the relay (unlike a mechanical relay which will flow in either direction).

Great

Used it for my simulated Perpetual Motion Machine. The Relay switches off and on within 0.1 Millisecond's which is quick enough for the 200 Millisecond's that the Electromagnet is on, and then off for 600 Millisecond's. Purchased two of them one for another project. The Solid State relay easily switches the 1.3 amps at 12 volts.

Worked as expected

i was able to use two of these to remotely start my generators (with the help of an Arduino) in my work shed.
