English | G4IDC5-SW G4 DC Input - DC voltage, self-powered, normally open |

an external dry contact switch. The G4IDC5-SW senses switch closure. Each user-supplied switch is connected with two
wires. Because the module includes power for the switch, this module is particularly cost-effective when labor costs for
wiring external power are high.
Opto 22’s G4 DC input modules provide up to 4000 volts (transient) of optical isolation between field inputs and the logic
output of the circuit. This module is designed with filtering on the input and a hysteresis amplifier, providing high noise
rejection and transient-free, “clean†switching.
Typical applications for the G4IDC5-SW include sensing contact closure from sources such as proximity switches, limit
switches, selector switches, push buttons, photoelectric switches, and TTL-compatible devices.
