Westinghouse 1C31234G31 Ovation Contact Input Module

The Westinghouse 1C31234G31 is a contact input module for Ovation distributed control system architectures. It is designed to acquire discrete field signals from contact devices and pass status information into the control platform. Typical use includes plant control, interlock handling, and process signal monitoring.

- Accepts discrete contact status from field devices such as switches and pushbuttons for controller-side state visibility.
- Uses optically isolated input channels to transfer contact state information while helping separate field-side signals from control electronics.
- Detects state changes from connected contacts and converts those transitions into monitored input status for system control logic.
- Supports Form A, Form B, and Form C contact types for integration with common discrete field signaling schemes.

- Provides 16 contact input channels for discrete signal acquisition.
- Operates at a nominal input voltage of 48 VDC.
- Includes built-in diagnostics for internal module fault detection and ground fault detection.
- Delivers typical response time of less than 5 ms for fast discrete status recognition.
- Fits Ovation I/O architectures as an electronic module for contact input handling.

- Monitors valves, solenoids, limit switches, and pushbuttons in industrial control environments.
- Supports safety interlock signal handling in process and plant systems.
- Collects discrete signal status for process monitoring and analysis workflows.
