I have a 1120VAC buzzer that has failed.
the wiring system to it is all 120VAC, but now I want to use a 12VDC buzer.
What I would like to do is to use this
I would just connect this to the existing 120VAC and the output to the buzzer.
when the existing relays signaled the buzzer to go of, the 120VAC would go hot and the power supply would output 12VDC
anyone know if there would be a problem turning the mains on and off to this ?
