Emerson Ovation 1C31197G05 Digital Input Module

The Emerson Ovation 1C31197G05 is a hot‑swappable digital input module for Ovation DCS distributed control system. It collects 24VDC discrete signals from field sensors, limit switches and auxiliary contacts, converts them into digital data and transmits to Ovation controller for equipment status monitoring and sequence‑control logic processing.

This rack‑slot I/O module adopts optical isolation for noise suppression, supports channel‑level fault diagnosis and front‑panel LED status indication. It must cooperate with matched field termination assembly. It serves as critical aftermarket spare for maintenance, overhaul and retrofitting of thermal‑power‑plant and petrochemical DCS control cabinets.
