Woodward 9907-014 2301A Speed Controller

Product Description: The 9907-014 is Woodward 2301A electronic speed governor, a classic analog speed and load-sharing control unit for diesel and gas generator engines. It receives pulse signal from magnetic pickup (MPU), compares actual engine speed with setpoint, outputs proportional drive signal to fuel actuator to stabilize engine RPM. This version is widely used as OEM spare for Caterpillar gensets (Caterpillar part 131-5453), supporting isochronous speed regulation and droop mode for generator paralleling applications.

Features:

• 2301A series fixed / variable speed electronic governor, 20–40 VDC power supply
• Magnetic pickup speed input, works with standard MPU speed sensor
• Supports isochronous and droop control mode for genset parallel operation
• Built-in gain, stability and speed setpoint potentiometers for on-site tuning
• Compatible with Woodward SPM synchronizer and external load sharing modules
• Panel chassis enclosure, easy mounting inside engine control cabinet
• Reverse polarity, overvoltage and actuator short-circuit protection

Applications:

• Diesel generator speed control for industrial standby power
• Caterpillar engine genset retrofit and spare replacement
• Gas engine generator set paralleling control system
• Oil & gas field engine-driven pump and compressor units
• Marine auxiliary generator speed regulation cabinet

FAQ:

Q: What is the difference between 9907-014 and other 2301A part numbers?
A: Different part numbers correspond to different factory firmware, actuator output range and OEM custom versions; 9907-014 is the Cat-specified variant.

Q: Can it directly replace old 2301 (non-A) governor?
A: Mechanical function is similar, but terminal definition and wiring are different, re-wiring and re-calibration are required.

Q: Is 9907-014 still in production?
A: 2301A series is obsolete. Available supply is NOS surplus or fully tested refurbished units.
