Emerson Ovation 1C31192G01 Contact Input Module

The Emerson Ovation 1C31192G01 is a contact input module for Ovation DCS distributed control system. It monitors dry‑contact status of field devices such as circuit breakers, relays and auxiliary switches, transmits contact on‑off status to Ovation controller via back‑plane bus for equipment status indication and safety interlock logic.

This hot‑swappable rack‑slot I/O module adopts optical isolation design, supports channel‑by‑channel fault diagnosis and front‑panel LED status indication. It needs to work 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.
