WESTINGHOUSE 5X00226G03

Description

Product Description
The WESTINGHOUSE 5X00226G03 is a legacy printed circuit board (PCB) assembly designed as a critical component within Westinghouse Ovation™ or WDPF (Westinghouse Distributed Processing Family) distributed control system (DCS) and PLC platforms. This component, like many bearing the WESTINGHOUSE designation, was engineered for high-reliability control and monitoring in demanding utility and industrial environments. The specific function of the WESTINGHOUSE 5X00226G03 is often as a specialized controller module, interface card, or processor daughterboard within a larger system chassis, responsible for executing control logic, managing I/O communications, or providing critical system services. These systems form the backbone of power generation and large-scale process automation. The durability and precision of the WESTINGHOUSE 5X00226G03 contributed to the legendary reliability of the control systems it served. As a legacy part, sourcing authentic and refurbished units for the WESTINGHOUSE 5X00226G03 is crucial for maintaining operational continuity in facilities with long-lifecycle assets.

Product Parameters

• Component Type: Printed Circuit Board (PCB) / System Module.
• Compatibility: Designed for integration into specific Westinghouse Ovation or WDPF system racks and chassis (exact series depends on module type).
• Function: Highly specific; typical functions could include: communication control (e.g., for I/O networks like Ovation I/O Bus), auxiliary processing, or specialized signal interfacing. Precise function requires cross-referencing with Westinghouse technical documentation.
• Processor/Memory: May incorporate period-specific microprocessors, RAM, and EPROM/Flash memory for firmware and application storage.
• Interfaces: Features board-edge connectors, onboard terminal blocks, or communication port headers specific to the Westinghouse architecture.
• Diagnostics: Relies on system-level diagnostics via the control platform’s engineering interface and may have status LEDs on the board itself.
• Power Requirements: Operates on DC voltages supplied by the host chassis’s backplane (e.g., +5V, +/-12V, +24V).

Advantages and Features

• Proven Reliability & Longevity: Engineered for the 24/7/365 operational demands of power plants, with a proven track record of stability in critical applications.
• Seamless System Integration: As a genuine OEM component, the WESTINGHOUSE 5X00226G03 guarantees full electrical and mechanical compatibility with the existing system, ensuring noise-free operation and data integrity.
• High-Quality Construction: Manufactured with industrial-grade components and robust PCB design to withstand temperature variations and electrical noise prevalent in industrial settings.
• Deterministic Performance: Provides the predictable, real-time response required for turbine control, burner management, and other fast-loop processes.
• Comprehensive Support Legacy: Supported by a specialized industry of third-party suppliers who provide refurbishment, testing, and lifecycle services for these essential legacy parts.

Application Cases in Industry

• Fossil Fuel Power Plants: Used within control systems for boiler control, turbine governor control, burner management systems (BMS), and feedwater regulation.
• Nuclear Power Plants: Employed in non-safety related control systems for balance-of-plant operations (e.g., cooling water, auxiliary systems).
• Large Industrial Processes: Found in complex DCS installations for chemical plants, oil refineries, and pulp & paper mills for unit-level or loop control.
• Hydroelectric Power Stations: Integrated into governor and unit control systems for managing generator output and wicket gate positioning.

Comparison with Competing Products
The WESTINGHOUSE 5X00226G03 does not have a direct “competitor” in the modern sense, as it is a proprietary component for a specific, closed architecture. Comparisons are more relevant to system-level migration. Versus modern PLC or DCS modules (from Siemens, Emerson, ABB), the Ovation/WDPF system and its components like the 5X00226G03 represent a different era of technology—often more specialized, less modular, and requiring proprietary knowledge for support. Its advantages are deep integration within an installed base and unparalleled field history. The disadvantage is technological obsolescence, potential difficulty in sourcing, and lack of modern features like web servers, advanced cybersecurity, and open Ethernet-based protocols.

Selection Suggestions and Precautions

• Selection Advice:
  1. Select the WESTINGHOUSE 5X00226G03 exclusively for like-for-like replacement in an existing Westinghouse Ovation or WDPF system to maintain original functionality and certification.
  2. Crucially, verify the exact firmware revision and hardware version against your failed unit or system BOM. Even slight variations (G01, G02, G03) can be critical.
  3. Source from reputable suppliers who provide full testing certification and a warranty to ensure you receive a functional, authentic component.
  4. Consider purchasing a sparing unit for critical applications to minimize future downtime.
• Precautions:
  1. Obsolescence: This is a legacy part. Long-term availability is not guaranteed by the OEM. Develop a lifecycle management plan.
  2. Configuration: Replacement modules often require specific firmware loading or configuration via proprietary Westinghouse tools (e.g., WDT) by qualified personnel.
  3. Electrostatic Discharge (ESD): Handle the WESTINGHOUSE 5X00226G03 as a static-sensitive device using proper ESD precautions during installation.
  4. System Impact: Ensure the host chassis is powered down correctly before removing or installing any module to prevent backplane damage or corruption. Always follow strict plant lock-out/tag-out (LOTO) procedures.
