Emerson Ovation 1C31169G02 Serial Link Controller Module

The Emerson Ovation 1C31169G02 is a serial link communication controller module for Ovation DCS distributed control system. It provides multi‑protocol serial interfaces including RS‑232, RS‑422 and RS‑485, realizes data interaction between Ovation controller and third‑party field devices such as instruments, analyzers and auxiliary control systems via Modbus and other serial protocols.

This rack‑slot hot‑swappable communication module supports protocol conversion and data buffering, equipped with communication status LED indicators and onboard fault diagnosis function. It is installed on Ovation I/O carrier chassis. It serves as critical aftermarket spare for maintenance, overhaul and retrofitting of thermal‑power‑plant and petrochemical DCS control cabinets.
