Emerson 1C31125G02 Ovation Digital Input Module

The Emerson 1C31125G02 is a digital input module designed for the Ovation distributed control system. It collects discrete status signals from field switches, contactors and equipment limit switches, and transmits digital status data to the Ovation controller for logic judgment.

This module supports multiple discrete contact signal acquisition and built-in channel diagnostic functions. It adopts industrial isolation design to resist on-site electromagnetic interference, widely supplied as spare parts for maintenance and renovation of Ovation DCS in power plants and petrochemical industries.
