I'm not sure what I'm looking for, but what I need is a relay switch that will control two things, or maybe two different relays are needed, I'm not sure.
Basically, from my Raspberry PI I want to control two things;
- An electrical outlet and it's power, with NC side wired, so that my plug is on unless I turn it off from the PI.
Part 1 can I do on my 2 channel relay:
I'm having trouble with part 2.
- Have another wire interrupted also at the same time the plug is turned off. This wire is it's own power source and will not be powered by the wall electrical line like the plug, I simply want to interrupt the line when off.
Not sure if I need a second relay or something else for this purpose, as I don't want the power from the wall routed to this secondary line.
