Woodward 9907-028 Speed Controller Module

Product Description

The Woodward 9907-028 is a high-performance digital speed control module for turbine and engine governing systems. It monitors shaft speed signals from magnetic pickups and executes closed-loop speed regulation, load control and protection logic. This module is widely used for gas turbines, steam turbines and reciprocating engines in power generation and oil & gas industries, serving as a critical spare part for on-site control cabinet maintenance and retrofit.

Product Functions

• Receive pulse signals from magnetic speed pickups to measure real-time shaft rotating speed
• Closed-loop speed governing, load sharing and droop control for prime movers
• Overspeed detection, underspeed protection and fault alarm functions
• Analog and discrete I/O interfaces for actuator drive, status feedback and interlock signals
• Onboard diagnostic circuits to identify pickup failure, signal loss and internal faults
• Support communication with host monitoring systems for parameter setting and data upload

Application Scenarios

• Gas turbine and steam turbine generator governing control systems
• Reciprocating engine power generation units and compression packages
• Oil & gas pipeline compressor and offshore platform prime mover control
• Industrial power plant and distributed generation speed control cabinets
• Spare replacement and repair of existing Woodward governor racks
