Is there a relay that uses a 110v trigger for a 12v output?
I know that this is probably the most backwards way to do things (and yes, I know, probably extremely stupid [but I'm also new to relays..]) , but I am in the process of trying to make a heated platform for my RepRap (I have gen 6, thus the reason for this). I have a PID controller, and I have the board running off an ATX power supply. So, what I would like to know if there is a relay that can use the 110v the PID controller to turn on/off the power from the ATX to the heat bed.
Thanks in advance!
