Emerson 5X00500G01 Ovation DCS 32-channel digital output module, 24VDC current sourcing outputs with inductive load protection, drives field relays and solenoid valves, supports hot-swap, widely used spare part for thermal power plant sequential control and interlock systems.

Product Overview

• Part No: 5X00500G01
• Brand: EMERSON / Westinghouse Ovation

• Category: 32-Channel Digital Output Module 5X00500G01 is a high-density digital output module for Emerson Ovation distributed control system. It receives control commands from Ovation controllers and provides 32 independent 24VDC current-sourcing outputs to drive field loads including relays, solenoid valves and auxiliary equipment. Built-in protection circuits suppress voltage spikes generated by inductive loads to extend service life and avoid hardware damage. The module features galvanic isolation between field circuits and internal backplane bus to eliminate ground loop interference. Hot-swap capability enables online module replacement without interrupting operation of other control loops. Front panel LED indicators display module running status, communication health and individual channel state for fast on-site inspection and fault diagnosis. It serves as essential maintenance spare for boiler, turbine and electrical sequential control as well as safety interlock applications in power generation facilities.
