G1 I/O family
The IDC5B can act as either a DC or AC input, accepting 4-16 VDC or VAC. Input modules are used for sensing ON/OFF voltage levels. This module is a fast-switching input module for signals produced by photoelectric switches or TTL level devices. Each module provides up to 4000 volts (transient) of optical isolation between the field inputs and the output side of the circuit.
