Configured for precise speed regulation and load sharing tasks in turbine and engine control architectures, the Woodward 9905-068 (2301A Speed Controller Module) provides direct physical/electrical execution. This analog-digital hybrid control module processes speed sensor inputs and external setpoints to modulate prime mover fuel actuators with high dynamic stability.

Suffix Breakdown & Model Matrix

• 9905-068: Standard 2301A load sharing and speed controller module variant featuring configured actuator driver outputs and isolated auxiliary input channels.

Hardware Specifications

Actuator Loop Feedback Response and Thermal Profiles

The hardware incorporates specialized operational amplifier networks designed to optimize actuator loop feedback response times during load transient events. Thermal heat sink dissipation profiles integrated into the cast chassis manage internal component junction temperatures when operating inside unventilated control panels. Built-in harmonic distortion suppression filters clean incoming magnetic pickup signals, ensuring steady governor operation despite heavy electromagnetic interference from nearby generator excitation fields.

Frequently Asked Questions

Q: What type of speed sensor input is required for this controller module?

A: The module accepts frequency inputs from standard magnetic pick-up (MPU) sensors mounted adjacent to the prime mover flywheel gear teeth.

Q: How is the load sharing configuration adjusted during parallel generator operation?

A: Load sharing adjustments are performed using onboard gain and reset potentiometers, balancing the proportional load distribution across interconnected generator sets via an analog low-voltage interconnect line.

Field Installation Guidelines

• Mount the module vertically inside an enclosed, grounded industrial control cabinet to ensure optimal convective heat dissipation across the housing fins.
• Run shielded twisted-pair cables for magnetic pickup and actuator output lines, terminating the shield drain wire exclusively at the cabinet ground stud to eliminate ground loops.
• Verify that the operating voltage source is stable and set to the rated nominal supply before closing the primary power input circuit breakers.
