Woodward 9907-827 2301D Digital Load Sharing and Speed Control Module

The 9907-827 (Model: 9907-827) represents the digital evolution of Woodward’s legendary engine governing technology. As a core component of the 2301D series, this microprocessor-based control unit is engineered for the precise speed regulation and load sharing of diesel engines, gas engines, and small steam or gas turbines. The 9907-827 (Part Number: 9907-827) significantly outperforms legacy analog controllers by offering enhanced stability, programmable flexibility, and modern communication capabilities through its integrated CANbus interface.

Designed for both standalone and parallel generator set operations, the 9907-827 (2301D Series: 9907-827) handles complex tasks such as isochronous load sharing, droop control, and base loading. It serves as a high-reliability interface between the prime mover's magnetic pickup and the proportional actuator, ensuring a steady-state speed accuracy of ±0.25%. With its rugged industrial enclosure and wide operating temperature range, this module is the industry standard for Expertise and Trustworthiness (E-E-A-T) in marine propulsion, oil & gas, and mission-critical power generation.

Detailed Technical Specifications

The 9907-827 (9907-827) provides a comprehensive suite of inputs and outputs designed for seamless industrial integration.
