Emerson 5X00497G01 Digital Input Module

The Emerson 5X00497G01 is a rack plug-in digital input module for the Ovation distributed control system. It collects discrete switch signals from field sensors and switches, converts them into digital data and transmits to the controller for equipment status monitoring and safety interlock logic judgment.

This module supports multi-channel signal acquisition and built-in channel fault diagnosis. It is widely stocked as spare parts for maintenance, cabinet reconstruction and system upgrade of Ovation DCS in power, petrochemical and process industries.
