Description
The Woodward 5464-647 2-Channel Actuator Driver Module is a digital control module designed for Woodward MicroNet and industrial turbine control systems. It provides two independent actuator driver channels for controlling proportional or integrating actuators used in steam turbines, gas turbines, compressors, and engine control applications.
The module converts control signals from the MicroNet controller into actuator drive outputs, enabling precise positioning control for fuel valves, steam valves, and other mechanical actuators. It features discrete digital control, panel mounting design, fault indication, and reliable operation in demanding industrial environments.
The 5464-647 is commonly used as a replacement spare part in legacy Woodward control systems where stable actuator operation and accurate speed/load regulation are required.
