Emerson Ovation 1C31116G04 Analog Input Module

The Emerson Ovation 1C31116G04 is a high‑precision analog input module for Ovation DCS distributed control system. It receives 4‑20mA current signals from field transmitters, completes analog‑to‑digital conversion, and transmits process variable data to Ovation controller for monitoring, calculation and closed‑loop control.

This hot‑swappable I/O module is equipped with channel‑level diagnostic and LED status indicators, and works with matched termination base assembly. It is widely adopted in power and petrochemical sites. It serves as critical aftermarket spare for DCS cabinet maintenance, overhaul and system retrofitting projects.
