Product Overview

The Woodward 9907-014 serves as a precision electronic governor within the globally recognized 2301A series. This module provides high-accuracy speed regulation and load sharing capabilities for diesel engines, gas engines, and steam or gas turbines. Configured as a Forward Acting unit, the 9907-014 increases its 0–200 mA output signal to command a corresponding increase in fuel or steam flow. It excels in both single-unit speed regulation and complex multi-engine parallel applications, ensuring deterministic performance during sudden load transients or grid synchronization. We supply this component in 100% Brand New and Original condition to guarantee Woodward’s signature analog reliability for your critical power infrastructure.

Engineering Advantages

The Woodward 9907-014 addresses the rigorous demands of industrial prime movers through specialized hardware features:

Optimized Forward Acting Logic: The 0–200 mA output ramp specifically matches forward-acting actuators. This ensures that in the event of a signal increase, the actuator opens the fuel rack or steam valve immediately, providing the rapid torque response required for frequency stability in standalone grids.
High-Frequency MPU Interface: The module supports a high speed-sensing range (up to 6000 Hz). This allows for precise monitoring of high-speed turbines or engines with high-tooth-count flywheels, resulting in smoother governing and reduced mechanical wear on the drive train.
Dual-Mode Operational Versatility: A simple jumper or switch configuration allows the 9907-014 to toggle between Isochronous mode (maintaining exact frequency regardless of load) and Droop mode (enabling proportional load sharing between multiple parallel units). This flexibility simplifies fleet standardization across different site architectures.
Thermal and Electrical Ruggedness: The unit operates reliably from –40°C to +70°C and tolerates wide DC input fluctuations (10–40 VDC). Its aluminum chassis acts as a natural heat sink, protecting the internal analog components from the thermal stresses typical of engine-mounted control cabinets.

FAQs

Is the Woodward 9907-014 supplied in original factory packing?

Yes. Every 9907-014 unit we ship is 100% Brand New and Original, arriving in Woodward's factory-sealed packaging. This ensures the unit has never been installed and meets all factory calibration standards for the 2301A series.

Can I use this module to replace a "Reverse Acting" 2301A unit?

No. The 9907-014 is a Forward Acting controller. If your system requires a Reverse Acting signal (where signal decrease leads to fuel increase), you must select the corresponding Woodward part number. Using the wrong acting logic will result in an immediate engine overspeed or failure to start.

Does the 9907-014 support remote speed adjustment?

Yes. The module includes terminals for an external speed trim potentiometer. It also accepts 4–20 mA or 1–5 VDC signals from a remote PLC or Synchronizer, allowing for automated grid matching and remote load control.

What is the benefit of the 0-200 mA output?

The 0-200 mA DC signal is the industry standard for Woodward’s hydraulic and electric actuators. This high-current signal provides the necessary power to drive the actuator coil directly, eliminating the need for intermediate signal amplifiers and reducing potential points of failure.
