Westinghouse 1C31194G02 Digital Output Module

The Westinghouse 1C31194G02 is a digital output module developed for Westinghouse distributed control systems. It receives logic commands from the main controller and outputs switching signals to drive field actuators, solenoid valves and contactors, realizing on-site equipment sequence and interlock control.

This module adopts optoelectronic isolation design to resist industrial electromagnetic interference. Equipped with channel status LED indicators, it supports long-term stable operation, widely used as replacement spare parts for overhaul and upgrade of DCS systems in power and petrochemical industries.
