OPT-G4IDC15

G4IDC15 G4 DC Input 10-32 VDC, 15 VDC Logic

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.

This module is designed with filtering on the input and a hysteresis amplifier, providing high noise rejection and
transient-free, “clean” switching.
