Hi All I am using a Decimilla and will need to control mains loads. I am using single outputs for each function. I would like to have LED's in the "loop" for diarnostics e.g. Output pin -> LED -> Relay -> Ground This should led me see the condition of the relays in the event of a failure.
What is the best way to wire in the relays/LED's? series/ parralel to ground?
What relays would you suggest, I will need to control: 240VAC @ upto 13A 120VAC @ upto 20A 24VAC @ 1A
P.s. is there a ready built relay board for doing this or at least some of it?
