G4 DC Input 10-32 VDC, 24 VDC Logic
G4 I/O family
The G4IDC24 is a digital DC input module with an input voltage range of 10-32 VDC (or 12-32 VAC), requiring a typical logic voltage of 24 VDC. This module is not compatible with Opto 22 brains.
This module is designed with filtering on the input and a hysteresis amplifier, providing high noise rejection and transient-free, “clean” switching.
Opto 22’s G4 DC input modules are used to detect on/off DC voltage levels. Each module provides up to 4000 volts (transient) of optical isolation between field inputs and the logic output of the circuit. Typical applications for DC input modules include sensing the presence or absence of voltage and sensing contact closure from sources such as proximity switches, limit switches, selector switches, push buttons, photoelectric switches, and TTL-compatible devices.
