Information

Overview Manuals Principle Core Applications

Features:

  • Load Sharing and Speed Control
  • 2301A Electronic Load Sharing and Speed Control
  • Designed specifically for multi-unit generator systems
As a sensor interface unit, it acquires and processes signals from connected sensors, converting raw physical measurement data into standardized electrical signals suitable for real-time monitoring. Its rugged design ensures signal integrity even in noisy or vibrating industrial environments, guaranteeing accurate and reliable data for process automation. Furthermore, the 9907-018 supports seamless integration with distributed control systems (DCS) and programmable logic controllers (PLCs), enabling centralized monitoring and collaborative control of complex machinery.

It continuously monitors operating parameters such as voltage, current, and temperature, issuing fault or status signals when anomalies are detected. This predictive capability allows maintenance teams to proactively address potential problems, minimizing unplanned downtime. Its modular design also facilitates expansion, allowing multiple 9907-018 units to be networked, extending coverage in large industrial systems while maintaining precise synchronization and data integrity.

The 9907-018 Woodward Load Sharing and Speed Control may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).
Woodward 9907-018 Load Sharing and Speed Control datasheet(manual), Link Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
The 9907-018 operates on the principle of precise signal conditioning and real-time conversion of sensor outputs to standardized measurement signals. Internal circuitry filters out noise and compensates for environmental influences, while high-speed processing ensures extremely low data transmission latency. The module continuously monitors its own operating status and takes protective measures against overcurrent, voltage spikes, or overheating, thereby ensuring stable, accurate, and fault-tolerant performance in industrial measurement and control networks.
Multi-unit generator systems: Used to maintain precise speed regulation and effective load distribution among multiple generator units operating in parallel or on independent busbars.
Prime mover control: Controls fuel metering devices (actuators) for various prime movers, including:
Engines: Diesel engines, gasoline engines, and gas engines.
Steam turbines: Steam turbines and gas turbines.
Industrial power management: Ensures reliable operation on independent power grids and interconnected "unlimited" busbars.

Technical notes

The Woodward 9907-018 is a low-voltage electronic speed control and load balancing module belonging to the 2301A series. It operates on a 20-40VDC power supply, features a single-channel positive-acting design, and outputs a 0-200mA current signal, allowing direct control of various actuators (such as Woodward EG, EGB, and TM series). The module integrates a self-sustaining load sensor, supports constant speed or droop speed control modes, and can receive 4-20mA or 1-5VDC process control signals. It is specifically designed for speed control and dynamic load balancing of prime movers such as diesel engines, gas turbines, and steam turbines in multi-unit grid-connected power generation systems. The entire hardware consists of a PCB board encapsulated in a metal housing with EMI/RFI shielding, and all adjustment potentiometers are directly operable from the front.
