I'm and hvac contractor. and i want to make a tester that i can plug directly in to circuit broads that have multiple 120vac signals. i want to make a tester to plug directly to the board to see if they are getting a voltage. i know i can just use a multi-meter just trying to make my job more efficient. I would like to be able to illuminate a few 5vdc leds. the circuit will share a neutral but multiple 120vac signals. Do they make a relay that will use a 5-12vdc relay that has a 120vac trigger?
Thanks in advance.
