The Woodward 5464-334 functions as the central intelligence for advanced prime mover control systems. Part of the renowned ProAct Series, this module executes high-precision speed and load regulation for industrial gas turbines, steam turbines, and large-scale diesel engines. It combines a high-speed 32-bit RISC processor with isolated (ISO) 4-20mA analog system cards to handle complex start-up sequencing, grid synchronization, and critical overspeed protection. Whether deployed in marine propulsion or stationary power generation, the 5464-334 ensures stable operation under dynamic load conditions.
The 5464-334 leverages a versatile I/O suite to maintain absolute control over the engine or turbine lifecycle.

Precision ISO Analog Interfacing: The 5464-334 incorporates an isolated 4-20mA analog input system. This isolation prevents ground loops and eliminates electromagnetic interference (EMI) that typically corrupts sensor data in high-voltage power plant environments.
Dual-Loop PID Logic: Independent speed and load PID loops allow the module to switch seamlessly between frequency control and base-load operation. This ensures the turbine remains stable during sudden grid disconnects or load rejections.
Rapid Response Processing: The 32-bit RISC processor executes control algorithms in less than 20 milliseconds. This ultra-fast reaction time protects rotating hardware from overspeed damage during massive step-load changes.
Industrial-Grade Survivability: Designed for the nacelle or engine room, the module withstands extreme temperatures (-40°C to +85°C) and continuous industrial vibration. The IP20-rated enclosure protects internal circuitry when mounted in standard industrial cabinets.
Global Compliance & Safety: The hardware carries ATEX Zone 2 and UL certifications, qualifying it for use in hazardous areas where explosive gases may be present.
100% Brand New Assurance: We supply only original, factory-sealed Woodward hardware. This guarantees that your critical control system operates with the full manufacturer-rated MTBF (Mean Time Between Failures).
Q: Can the 5464-334 replace other modules in the ProAct Series?
A: The 5464-334 features specific ISO 4-20mA analog input capabilities. While it shares the ProAct architecture, always verify your specific software configuration and I/O requirements in the ProAct Configuration Suite before a replacement.
Q: Does the module support remote monitoring?
A: Yes. The module supports multiple industrial protocols including Modbus TCP/IP and EtherNet/IP. This allows for real-time data streaming to a DCS or SCADA system for remote diagnostics and performance logging.
Q: How does the module sense turbine speed?
A: The module accepts signals from up to two magnetic pickups (MPU) with a frequency range of 4 to 10,000 Hz. It can also use a 4-20mA analog signal as a secondary or auxiliary speed reference.
Q: What are the installation requirements for hazardous areas?
A: For ATEX Zone 2 compliance, you must install the 5464-334 inside a tool-accessible protective cabinet that meets the appropriate IP rating for your specific environment.
