Emerson 5X00499G01 Ovation DCS 32-channel digital input module, accepts 24VDC discrete contact signals, collects valve feedback, breaker auxiliary and equipment status signals, supports hot-swap operation, widely used spare part for thermal power plant sequential control and interlock systems.

Product Overview

• Part No: 5X00499G01
• Brand: EMERSON / Westinghouse Ovation

• Category: 32-Channel Digital Input Module 5X00499G01 is a high-density digital input module designed for Emerson Ovation distributed control system. It acquires on/off status signals from field limit switches, breaker auxiliary contacts, valve position feedback and equipment status switches, and converts discrete field signals into digital data for Ovation controllers. The module accepts 24VDC field contact inputs and supports software configurable signal debounce time to suppress contact bounce interference. Galvanic isolation is implemented between field circuits and internal backplane bus to avoid ground loop and electromagnetic noise interference. Hot-swap capability enables online module replacement without interrupting signal acquisition of other channels. Front panel LED indicators display module operating status and individual channel signal state for convenient on-site inspection and fault diagnosis. It acts as critical maintenance spare for boiler, turbine and electrical sequential control as well as safety interlock applications in power generation facilities.
