G1 I/O family
The IDC24 can act as either a DC or AC input, accepting 10-32 VDC or 12-32 VAC. All AC and DC input modules have a bridge-rectifier input. Each module provides up to 4000 volts (transient) of optical isolation between the field inputs and the output side of the circuit.
Input modules are used for sensing ON/OFF voltage levels. Typical uses and applications include sensing the presence or absence of voltage or sensing contact closures from sources such as:
