In addition, the IN-ISO module allows the control of the RXC with AC or DC voltages and currents over greater distances than normally available to the RXC.
The IN-ISO module has 8 independent and isolated inputs that accept voltages ranging from 12V to 120V AC or DC. Since the opto-isolator is a current driven device, switches can be remotely placed at a great distance from the IN-ISO. As long as the current is sufficient to activate the opto-isolator, the input to the RXC will be held low (Active).
