FUNCTIONAL DESCRIPTION:
The 5464-645 is a 2-channel Actuator Driver Module designed for the Woodward MicroNet and NetCon 5000 control systems. Its primary function is to translate digital control commands from the Master CPU into the high-power analog signals required to drive fuel valves and steam turbine actuators. By providing precise current control, this module ensures that the prime mover's fuel or steam flow is modulated accurately to maintain stable speed and load conditions.
PRECISION AND DRIVE CAPABILITY:
Each of the two independent channels on the 5464-645 is capable of driving a wide range of Woodward and third-party actuators. The module can be configured for standard 0–20 mA low-power signals or higher current 0–200 mA outputs, depending on the requirements of the mechanical interface. With a 5 ms update rate, the module provides the deterministic performance needed for high-speed governor response, ensuring that the actuator reacts instantaneously to load transients or system disturbances.
INDUSTRIAL PROTECTION AND DIAGNOSTICS:
Engineered for the demanding environments of power plants, the 5464-645 features 500 Vdc galvanic isolation to shield the sensitive system backplane from field-side electrical noise and surges. The module is equipped with advanced onboard diagnostics that continuously monitor the health of the output loops. It can detect critical faults such as:
If a fault is detected, the module reports the status to the CPU, allowing the system to initiate safe-state logic or switch to a redundant driver if available.
AVAILABILITY AND SUPPORT:
World of Controls stocks the 5464-645 Actuator Driver Module in both unused and professionally rebuilt conditions to support the long-term reliability of your control system. Every unit is subjected to rigorous load testing to ensure linear output performance and accurate fault detection across both channels. Our global technical support team is available 24/7 to assist with actuator calibration, hardware configuration, and expedited logistics.

What is the Woodward 5464-645?
It is a 2-channel driver module for MicroNet and NetCon systems. It provides the analog current (up to 200 mA) required to position fuel valves and actuators on turbines and large engines.
Can I drive two different types of actuators with one module?
Yes. Since the two channels are independent, they can be configured for different output ranges and assigned to different control loops (e.g., one for fuel gas and one for fuel oil) within the system software.
How do I test the actuator response?
Technicians can use the Woodward GAP software or a service tool to manually override the output signal during commissioning or maintenance. This allows for the verification of full-stroke movement and calibration of the actuator's mechanical stops.
