Description

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.

All DC input modules except the G4IDC5K and G4IDC5D are

designed with filtering on the input and a hysteresis amplifier,

providing high noise rejection and transient-free, “clean”

switching. The G4IDC5K is a fast-switching module used to

detect signals produced by photoelectric switches and TTL

devices. The low-cost G4IDC5D is used for data acquisition.

The G4IDC5MA is a special module featuring a manual-on/

manual-off/automatic switch, ideal for diagnostic testing of

control applications.

The G4IDC5-SW and G4IDC5-SWNC modules supply power to

an external dry contact switch and sense switch closure (SW)

or opening (SWNC).

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.
