Description
The WOODWARD 9907-014 2301A Speed Control is an electronic engine governor controller designed for precise speed regulation of diesel engines, gas engines, and turbine-driven generator systems. It belongs to the Woodward 2301A Electronic Load Sharing and Speed Control Series and is widely applied in industrial power generation, marine propulsion, compressors, and mechanical drive systems.
The 9907-014 is a low-voltage speed control model designed for 20–40 VDC power supply applications. It receives speed feedback signals from a magnetic pickup sensor and controls an actuator to maintain stable engine speed. The unit supports isochronous speed control operation and is suitable for fixed-speed generator applications.
This controller provides reliable engine speed management with adjustable parameters for rated speed, stability, gain, and actuator response. It is commonly used as a replacement controller in legacy Woodward governor systems and industrial engine control installations.
