Emerson Ovation 1C31179G01 RTD Resistance Temperature Detector Input Module

The Emerson Ovation 1C31179G01 is a hot‑swappable RTD input module designed for Ovation DCS distributed control system. It receives resistance signals from PT100 and other RTD temperature sensors, converts resistance values into accurate temperature data, and transmits measurement results to Ovation controller for equipment temperature monitoring and over‑temperature interlock protection.

This rack‑slot I/O module supports multi‑channel RTD signal acquisition, built‑in wire‑break detection and front‑panel channel status LED indicators. It needs to cooperate with matching field termination assembly. It serves as critical aftermarket spare for maintenance, overhaul and retrofitting of thermal‑power‑plant and petrochemical DCS control cabinets.
