Emerson Ovation 1C31107G01 Digital Input Module

The Emerson Ovation 1C31107G01 is a plug‑style digital input I/O module for the Ovation DCS system. It collects 24 VDC discrete contact signals from field‑site auxiliary switches, limit switches and interlock devices, converts field status into digital signals and transmits data to the Ovation controller via the back‑plane bus.

This module adopts optical isolation to resist industrial interference, supports hot‑swap operation and channel‑by‑channel LED status indication. It is installed on the matching Ovation I/O base unit. It is an important aftermarket spare for power plant and petrochemical DCS cabinet maintenance, overhaul and hardware retrofitting projects.
