Westinghouse 1C31233G04 Contact Input Module

Westinghouse 1C31233G04 Contact Input Module 

Description

1C31233G04 is a 16-channel digital input module of the Westinghouse (Emerson) Ovation distributed control system. It is specifically designed to collect on-site dry contact signals and can monitor the operating status of equipment such as motors, valves, and switches in real time. It is a key I/O component for implementing process monitoring and interlock protection in DCS systems.

This module integrates optical isolation, event sequence recording (SOE), and signal debouncing functions. It supports 48VDC on-site power supply input and has millisecond-level timestamp accuracy. It is widely used in industrial scenarios such as power and petrochemical industries, meeting the requirements for high reliability and high precision status collection.

Features

• Compatible with the Ovation DCS system, providing 16-channel dry contact digital input
• Channel-level optical isolation, anti-electromagnetic interference, ensuring system safety
• Support SOE event sequence recording, with 1-millisecond timestamp accuracy
• Configurable signal anti-jitter filtering to eliminate contact jitter interference
• Monitor the status of 48VDC on-site power supply, automatically triggering alarms in case of abnormalities
• Wide temperature operating range, suitable for harsh industrial environments
