WOODWARD 9907 – 164 Governor control unit

WOODWARD 9907-164 is a governor control unit based on 505 and 505E microprocessors, used for controlling steam turbines, turbine generators, and turbine expander modules. It controls the steam turbine by operating a single extraction and/or intake of the turbine, and uses its split actuator to drive the steam inlet valve. It can be configured by on-site operators. Support multiple input/output interfaces, capable of connecting different types of sensors and actuators; It has functions such as electro-hydraulic conversion, speed control, load control, and can also achieve data acquisition and monitoring.
