Relay ISOx16 Module


Sorry about the newb question but can someone describe the proper way to physically hook up the relay board for example to a lamp. I searched but could not find a visual example.


Thanks. I should have specified I currently own the device. My question is specific to wiring. I take it that the relay needs separate power 12v source but I have never used a relay so being cautious.


Can you clarify “contact 1 or contact 2”?


Basicly this is what you have to wire. And then control the wired relais from your code.


You mean in a practical situation? it’s just a educational drawing :wink:

[edit] these are changeover contacts no?
[edit2] yes these are changover contacts.


Thanks David thats basically what I wanted to see.

Thanks all.
