The Woodward 9907-019 is an electronic load sharing and speed control module from the 2301A series, designed for precise control of engines in critical industrial and power generation settings. This model is specifically a low-voltage, reverse-acting version operating at 20-40 V DC to manage actuator fuel control signals for engines requiring accurate speed regulation and load sharing among multiple units. The 9907-019 controller is widely used in power plants, compressor stations, and marine propulsion systems where stable speed control and equitable load distribution are essential for optimal plant efficiency and mechanical longevity.
Functionally, the 9907-019 supports individual actuator systems and is designed to deliver reverse-acting control, meaning the actuator responds inversely to control voltage changes—fuel increases as voltage decreases. This behavior allows a backup mechanical governor to take over control safely if electronic power is lost without causing engine shutdown, improving system resilience. The controller supports continuous speed range selection up to 12,000 Hz with switch-selectable options to fit specific engine requirements. It operates without a deceleration ramp, providing immediate down-ramp speed reduction, which may be suitable for particular operational preferences or safety needs.

The module features multiple discrete inputs, analog outputs (4-20 mA), and relay outputs rated for standard industrial voltages, enabling flexible integration within engine control panels. Its solid aluminum housing provides robust protection in industrial environments. The controller requires shielded cable wiring to reduce interference and ensure signal integrity.
Related products in the 2301A series include various models like the 9907-018 (forward-acting, similar specs), 9907-020 (with deceleration ramp), and high-voltage variants designed to cover a broad range of industrial engine control applications.
Installation involves secure panel mounting with proper grounding and wiring following manufacturer recommendations. Maintenance best practices include verifying actuator connectivity, performing signal calibration, and inspecting electrical connections. Firmware updates and diagnostic checks can be performed using compatible programming tools.
