Hi All,
I'm a newbie here. I'm currently working on a device that controls 220V AC equipments via an electromechanical relay. The relay and the low voltage electronics are all housed in one enclosure. The connections between my electronics and the relay are VCC, GND and CONTROL line for turning on/off the relay. In this setup, how can I protect my electronics from the AC voltage in cases like there is a faulty relay or that the AC wiring is shorted with the VCC, GND or CONTROL lines? Thanks!
