I have one board that supports multiple relays and goes to a timed sequence. I need to initiate a second board from the first to support a second multiple relay sequence. How can I accomplish this?
Hi William,
The most straightforward way would be to utilize one of the relays on the first board to trigger an input into the second board.
What is the best way to do that? Is it as simple as wiring one relay on one board to the relay on the other board?
Hi,
Usually you would connect the ground of board 2 to the Common of one of the relays on board 1, then connect the NO connection of that relay on board 1 to one of the ADC inputs on board 2. This will be a contact closure and can trigger events based on the state of the input on board 2.
