Woodward 5461-002 Digital Microprocessor Controller for Steam Turbines
1. Product Description
The Woodward 5461-002 is a microprocessor-based controller designed for steam turbine applications, specifically engineered to automate speed and load control in single or dual actuator configurations. As part of Woodward’s renowned 505 control system, the 5461-002 operates in two modes: programming mode for parameter configuration and operating mode for real-time turbine management. It interfaces with Woodward’s I/H converters to convert electrical signals into hydraulic commands, adjusting the main steam valve opening to maintain precise turbine speed. This compact, rugged unit supports integration with Woodward governors (e.g., 505E, 505C) and third-party systems, making it ideal for power generation, petrochemical, and industrial process plants.

5. Competitor Comparison
- Superior Integration: Seamless compatibility with Woodward’s comprehensive control ecosystem (e.g., 505E, 505H).
- Cost-Effective Retrofit: Direct replacement for older 505 series models without hardware modifications.
- Advanced Diagnostics: Real-time monitoring and alarm history simplify maintenance.
6. Selection Recommendations
- Actuator Type: Choose dual actuator models for high-power turbines requiring redundant control.
- Communication Needs: Opt for Modbus RTU variant for SCADA integration.
- Environment: Use standard 5461-002 in general conditions; upgrade to extended-temperature models for extreme climates.
7. Precautions
- Wiring: Ensure proper PT/CT connections to avoid signal interference.
- Calibration: Regularly verify hydraulic actuator response using Woodward’s test procedures.
- Software Updates: Keep firmware current via Toolkit software to access new features.
- Installation: Mount in a vibration-free enclosure with adequate ventilation.
