Product Overview

The 1C31166G02 is an EMOD serial link controller card for the Emerson Ovation DCS platform, originally released under Westinghouse. It acts as a dedicated communication bridge between the R1120 controller and external serial field devices, eliminating protocol mismatch bottlenecks for legacy instruments, smart transmitters, meters and auxiliary control equipment. It supports RS485 multi-drop wiring and standard serial protocols, offloading serial polling workload from the main CPU to preserve controller scan performance. Built for high availability power and process plants, this module provides isolated serial communication, diagnostic status reporting and hot-swap capability, making it a critical spare for retrofit and maintenance in fossil power, combined-cycle and heavy industrial control systems.
