Channel Optocoupler Support Trigger Arduino Review

As an industrial and scientific buyer I was not pleased with this product .As a result of using this item, I found that it WAS not reliable and had inconsistent readings. The setup process was also complicated and frustrating. On the bright side, it did have some potential to be useful in the right hands. However, in my experience, it was not worth the investment..

Great relays to use with Arduino. Arduino digital pins are good for triggering relays. I'm using a Peltier module and pump, both of which use a relay, and the Arduino's digital output pins trigger the relay.
