Emerson 5X00502G01 Ovation DCS analog input module, 16 differential channels supporting 4–20mA signals, 16-bit high precision acquisition, channel-to-channel galvanic isolation, collects pressure, flow and temperature transmitter data, key spare for power plant Ovation control system.

Product Overview

• Part No: 5X00502G01
• Brand: EMERSON / Westinghouse Ovation

• Category: 16-Channel Differential Analog Input Module 5X00502G01 is a high-density analog input module developed for Emerson Ovation distributed control system. It acquires 4–20mA DC analog signals from field smart transmitters, converting analog measurements into digital data for Ovation controllers to execute monitoring and closed-loop regulation. Adopting differential signal sampling architecture, it effectively suppresses common-mode interference and ground loop noise in power plant environments. Each channel supports independent configuration of filtering parameters and signal scaling. Built-in comprehensive channel diagnostics detect open-circuit, short-circuit and out-of-range faults to support predictive maintenance. The module supports hot-swap operation to enable online replacement without interrupting unit operation. Front panel LED indicators display module operating status and channel fault alarms for fast on-site troubleshooting. Widely used maintenance spare for boiler and turbine process parameter monitoring loops in thermal power plants.
