Emerson 1C31132G01 Digital Input Module

The Emerson 1C31132G01 digital input module is designed for the Ovation distributed control system. It collects discrete status signals from field limit switches, valve feedback and relay contacts, and transmits digital status data to the Ovation controller for control logic processing.

This module supports multi-channel contact signal acquisition and integrates channel self-diagnosis function. It adopts channel isolation design to resist complex industrial electromagnetic interference, widely supplied as spare parts for maintenance and upgrade of Ovation DCS in power plants and process industries.
