Emerson 1C31224G01 Ovation DCS 8-channel analog input module, 4-20mA signal acquisition spare card for power plant distributed control systems.

Product Overview

• Part No: 1C31224G01
• Brand: EMERSON (Westinghouse Ovation)

• Category: 8-Channel Analog Input Module 1C31224G01 is an 8-channel analog input module designed for Emerson Ovation distributed control system. It receives 4–20mA standard current signals from field transmitters including pressure, flow and temperature sensors, and converts analog signals into digital data for Ovation controllers to implement closed-loop process regulation. Each channel adopts independent signal conditioning circuit with galvanic isolation to suppress field electromagnetic interference. The module supports hot-swapping, enabling online replacement without system shutdown. Front panel LED indicators display module operation status and channel fault alarms for convenient on-site inspection. It serves as critical maintenance spare for overhaul and retrofit of thermal power plant boiler and turbine control systems.
