Emerson Ovation 1C31194G03 Relay Output Module

The Emerson Ovation 1C31194G03 is a hot‑swappable relay output module for Ovation DCS distributed control system. It receives logic control commands from Ovation controller over the back‑plane bus, and actuates built‑in mechanical relay contacts to provide hard‑contact switching signals for trip protection, alarm output and auxiliary equipment control in power plant automation.

This rack‑mount I/O module adopts reliable mechanical relay outputs, supports channel‑level fault diagnosis and front‑panel LED status indication. It requires matching field termination assembly for field‑wiring connection. It is an important aftermarket spare for thermal‑power‑plant and petrochemical DCS cabinet maintenance, overhaul and retrofitting projects.
