Interfacing the relay modules to the Arduino. You need to connect the Arduino 5v to the 4 Relay board VCC pin and the Arduino ground to the 4 Relay board.
RelayIsolation. Edit 0 17 0 Tags. No connects the Arduino circuitry to the relay and switching parts. Notice that board has a jumper between Vcc and JD.
Relays. Relays are This contains a jumper between VCC and VCCJD. This means that the relay will be powered from the same 5V signal as the Optoisolators and LEDs.

I am trying to understand how I would use this relay board: And then do I put 12v across it where it says jdvcc, Board VCC to Arduino 5V
