Product Description

The 9907-031 is a digital control module from Woodward Inc.’s 2301D series, designed for speed governing, load sharing, and synchronization control of reciprocating engines (diesel, gas, or gasoline).

As the digital successor to the 2301A analog governor, it provides software-configurable control logic, improved stability, and higher precision engine dynamics management. The module is commonly used in mission-critical power generation, marine propulsion, and standby power systems.

The controller supports dual-speed sensing inputs, enabling redundant safety monitoring and improved overspeed protection reliability.

FAQ

Can it replace the 2301A analog governor?
Yes, but configuration must be performed using Woodward Watch Window software to tune PID parameters for specific engine applications.

Why use dual-speed inputs?
Dual inputs provide redundancy and cross-check validation, improving overspeed protection and system reliability.
