1C31181G02 Westinghouse Redundant Power Supply Module Remote I O Module

Westinghouse Emerson Ovation 1C31181G02 Remote I/O Module New Version Power Supply Redundancy Module

• High-Density & High Reliability:​ Provides multiple isolated input channels in a single module slot, optimizing chassis space. It is built to the rigorous standards of the Ovation DCS, ensuring maximum availability and mean time between failures (MTBF) critical for continuous process operations.
• Advanced Signal Conditioning & Isolation:​ Each input channel typically features high-grade optical or magnetic isolation, protecting the sensitive control system from high-voltage transients, ground loops, and electrical noise present in industrial environments, ensuring signal integrity.
• Diagnostic Capabilities:​ Incorporates comprehensive diagnostics, including per-channel status indicators (LEDs) and module health monitoring. Fault conditions (such as field power loss or channel faults) can be reported to the Ovation controller for proactive maintenance and reduced troubleshooting time.
• Hot-Swappable Design:​ Designed to support hot-swapping in qualified Ovation systems, allowing for module replacement or maintenance without requiring a full system shutdown, thereby maximizing plant uptime and operational continuity.
• Flexible Configuration via Software:​ Module parameters, such as debounce filtering and alarm settings, are configured within the Ovation engineering software, allowing customization to match specific field device characteristics and application requirements without hardware adjustments.
• Robust Industrial Design:​ Constructed to operate reliably in typical control room or enclosure environments, with protection against electrostatic discharge (ESD) and electrical fast transients (EFT).

• Material:​ The module utilizes a robust metal or high-strength composite chassis for EMI shielding and durability. The internal printed circuit board (PCB) is manufactured with industrial-grade components, conformal coating for environmental protection, and utilizes high-reliability connectors. Input isolation is achieved via optocouplers or isolation transformers.
• Primary Applications:
  • Power Generation:​ Monitoring turbine auxiliaries, pump statuses, breaker positions, and safety system permissives in fossil, nuclear, and renewable plants.
  • Oil & Gas:​ Monitoring valve positions (open/close), pump run status, tank level switches, and fire & gas system inputs in upstream and downstream facilities.
  • Water/Wastewater:​ Tracking pump and valve status, alarm conditions from filters and clarifiers, and level switches.
  • Chemical Processing:​ Monitoring motor starters, safety interlock status, and batch sequence steps.
