Description
The Woodward 9907-018 is a 2301A Load Sharing and Speed Control designed for industrial prime mover control applications. It is used to regulate the speed of diesel engines, gas engines, steam turbines, and other compatible prime movers while supporting load-sharing functions in parallel operating systems.
The controller receives a speed signal from a magnetic pickup and compares the actual speed with the configured reference. It then provides a proportional output signal to the actuator to regulate fuel or steam input and maintain the required operating speed. In generator applications, the 2301A Load Sharing and Speed Control can also help multiple units share load proportionally during parallel operation.

❓ Frequently Asked Questions
🔸 Q1: What is the main function of the Woodward 9907-018?
The 9907-018 controls the speed of a compatible prime mover and supports load sharing when generators or other prime movers operate in parallel.
🔸 Q2: What types of equipment can it control?
Typical applications include diesel engines, gas engines, generator sets, steam turbines, and gas turbines when used with compatible actuators and speed-sensing equipment.
🔸 Q3: What does “forward acting” mean?
A forward-acting configuration means the controller output operates according to the actuator direction required by the configured fuel or energy control system. The replacement unit must match the control action required by the existing application.
🔸 Q4: What is the actuator output range?
The 9907-018 configuration is associated with a 0–200 mA actuator output range.
🔸 Q5: What power supply does this controller require?
The 9907-018 is identified with a 20–40 VDC supply range. Verify the exact nameplate and installation documentation before connecting power.
🔸 Q6: Can it be used for parallel generator load sharing?
Yes. The 2301A Load Sharing and Speed Control platform is designed to monitor speed and support proportional load sharing between compatible generators operating in parallel.
🔸 Q7: Does the 2301A use programming software?
The Woodward support information lists the 2301A as a legacy controller without a dedicated software configuration tool. Configuration is primarily performed through the controller’s hardware adjustments and system wiring.
🔸 Q8: What should be checked before replacing a 9907-018?
Verify the complete part number, control action, supply voltage, actuator current range, speed sensor configuration, actuator type, load-sharing wiring, and existing system settings before replacement.
🔸 Q9: Can a different 2301A model directly replace the 9907-018?
Not necessarily. Different 2301A versions can have different supply-voltage ranges, actuator current ratings, forward or reverse action, and application configurations. The complete part number should always be matched.
