Description
Woodward 9907-164 is a high-performance electronic governor module primarily used to control the speed and load of rotating equipment such as gas turbines, steam turbines, and internal combustion engines.
· parameter
· Input power supply: 24V DC (± 10%), power consumption of approximately 15W
· Working temperature: -20 ° C to+70 ° C
· Storage temperature: -40 ° C to+85 ° C
· Speed measurement range: 0-30000 RPM (configurable)
· Control output: analog quantity (such as 4-20mA) or digital quantity
· Protection level: IP20 (to be installed inside the control cabinet)
· Weight: Approximately 1.5kg
· Key Features
· High precision control: supports precise speed regulation (± 0.1% steady-state accuracy) to ensure stable operation of the equipment under various load conditions.
· Multiple control modes:
· Speed control: Maintain a constant rotational speed.
· Load control: Automatically adjust output power according to load demand.
· Proportional control: Adjusting in proportion to external signals.
· Communication interface:
Supports industrial protocols such as Modbus RTU and Profibus, making it easy to integrate into DCS or PLC systems.
Analog input/output (such as 4-20mA, 0-10V) is used to connect sensors and actuators.
· Protection function:
· Overspeed protection: The protection mechanism is automatically triggered when the speed exceeds the set value.
· Fault diagnosis: Built in self diagnostic function, real-time monitoring of system status and providing alarm output.
· Flexible configuration: Personalized settings can be made through software or hardware parameters to adapt to different device needs.
