Westinghouse Remote I O Module 1C31189G01 RTD INPUT MODULE Redundant Power Supply Module
The Westinghouse 1C31189G01 is a highly reliable Analog Input Module designed for the OVATION™ Distributed Control System (DCS). This module serves as a critical interface between the control system and field instruments, receiving analog signals from devices like transmitters (pressure, temperature, flow) and converting them into digital values for processing by the OVATION controllers. It is engineered for use in demanding industrial environments such as power generation, water treatment, and large-scale process industries, where accuracy and long-term stability are paramount.
- • High-Density Channel Configuration:Supports multiple analog input points, optimizing cabinet space and reducing cost per point.
- • High Accuracy and Resolution:Provides precise measurement of field signals, ensuring accurate process monitoring and control.
- • Signal Isolation:Features channel-to-channel and channel-to-system isolation to protect the system from ground loops and high-voltage transients in the field, enhancing overall system reliability.
- • Hot-Swappable Capability:Allows for module replacement without powering down the entire system, minimizing downtime during maintenance.
- • LED Status Indicators:Provides clear visual diagnostics for power, communication, and channel status for quick troubleshooting.
- • OVATION System Integration:Seamlessly integrates with the OVATION controller and is configured using the OVATION software tools, simplifying engineering and maintenance.
1C31189G01 Material & Applications - • Materials:The module is constructed on a robust printed circuit board (PCB) with industrial-grade components. It is housed in a metal carrier for EMI/RFI protection and heat dissipation, and features high-quality terminal connectors.
- • Applications:Primarily used in OVATION DCS for power plants (thermal, nuclear, hydro) and large industrial processes. It connects to:
- • Temperature Transmitters (RTDs, Thermocouples)
- • Pressure and Flow Transmitters
- •
- • Valve Position Feedback Signals
