OPTO 22 G4IDC5K Digital Input Module

The G4IDC5K is a digital DC input module designed to detect ON/OFF voltage levels. It offers up to 4000V of transient optical isolation between field inputs and the circuit's logic output. The module features fast switching capabilities for detecting signals from photoelectric switches and TTL devices. Its typical applications include sensing voltage presence or absence and contact closure from proximity switches, limit switches, selector switches, and push buttons. It includes a built-in LED indicator for status, a compact design that reduces mounting space by about 50%, built-in filtering for transient suppression and noise rejection, and meets standards such as the NEMA showering arc test and IEEE surge withstand specifications. The module has a quick turn-on and turn-off time of 0.025 milliseconds, suitable for automation and industrial process control environments.
