About AM3000EX Isolated Safety Barrier
HollySys AM3000EX isolated safety barriers is a backplane-mounted system, consisting of plug-in modules and a backplane. Each module features two connectors for insertion into the backplane-one for the intrinsically safe circuit and the other for the non-intrinsically safe circuit. The backplane provides power supply terminals and wiring terminals for connecting to the hazardous area.
