Description
Real-World Use & Application Scenarios
The Woodward 2301E digital load sharing and speed control module is widely used in power generation, marine propulsion, and industrial engine applications where multiple generators or prime movers operate in parallel. It is designed to provide precise load sharing and speed regulation, ensuring balanced distribution of load among units, smooth transitions during loading and unloading, and stable engine speed control.
Industries relying on diesel or gaseous engines for power generation need the 2301E to monitor and control generators efficiently, prevent overload conditions, and maintain grid stability. It addresses key challenges such as dynamic load fluctuations, speed variation management, and adapting to different engine types or gearing configurations, making it ideal for new installations or upgrading existing 2301A and 2301D control systems.
Product Introduction & Positioning
The Woodward 2301E (8273-1011) is a microprocessor-based digital controller that combines functionality from previous 2301A and 2301D models with enhanced software flexibility. It supports configurable application parameters such as engine speed range, gear tooth count, and forward or reverse acting modes through external computer setup using Control Assistant or Woodward ToolKit software.
This module operates from a 24 V DC power supply and includes built-in load sensor circuits, an actuator driver supporting multiple output types (4–20 mA, 0–20 mA, 0–200 mA, or PWM), an MPU speed sensor input, configurable analog I/O, and multiple discrete inputs and relay outputs. With Modbus RTU communication over RS-422 and serial RS-232 ports, the 2301E integrates well into modern control networks.
Key Technical Features & Functional Benefits
The Woodward 2301E offers four operating modes—Speed Control, Isochronous Load Sharing, Droop Base Load, and Isochronous Base Load—providing versatile control strategies to match various operational requirements. Soft load transfer capabilities ease adding or removing units from the bus without disruption.

It incorporates multiple dynamic adjustments, manifold air pressure limiting, torque limiting, and low-speed sensing for enhanced engine protection and performance optimization. Accurate speed regulation is achieved through adaptive sensing algorithms, with a capability for remote speed and load reference input.
Its rugged sheet-metal chassis is suitable for ordinary and hazardous environments, with an operating temperature range from –40 to +70 °C. The control comes configured by external software tools through a 9-pin RS-232 port and supports data logging for events like shutdown and peak load conditions.
