Westinghouse 1C31194G03 Digital Output Module

The Westinghouse 1C31194G03 is a digital output module designed for Westinghouse legacy distributed control systems. It receives control commands from the main controller and converts internal logic signals into field switching signals to drive solenoid valves, contactors and other on-site actuators.

This module adopts optoelectronic isolation technology to suppress electromagnetic interference in industrial environments. Channel status LED indicators are equipped for convenient fault checking, widely stocked as spare parts for maintenance and upgrading of DCS systems in power and petrochemical industries.
