Woodward 8440-2050 Controller module

Woodward 8440-2050 is a controller module manufactured by Woodward Corporation of the United States, which belongs to the Woodward Company's product family of digital speed controllers. The design of this controller module is very flexible and is mainly used for steam turbine control, but can also control the utility turbine generator and turbine expansion model 3.

Functional characteristics

Governor: The Woodward 8440-2050 controller module is a self-contained independent oil source, mechanical hydraulic differential governor for small steam turbines1 that do not require synchronous (constant speed) operation.

Digital control modules: These units are very flexible and are primarily used for steam turbine control, but are capable of controlling common turbine generators and turbine expansion models. The unit is listed as 9907-170 and is a standard Woodward 505E microprocessor-based control unit.

Control capabilities: The 9707-170 is equipped with a 32-bit microprocessor unit to handle control capabilities, followed by a series of printed circuit boards.

Operation Configuration: The control panel displays two lines of text, each of 24 characters, for configuring the operation specifications of the 907-170 device.

Compatibility: Compatible with most existing analog load sharing speed control systems, it now has soft load and unload capabilities. Provides constant load level operation for utility buses.

Application scenario

The Woodward 8440-2050 controller module is mainly used in small steam turbines or other similar industrial equipment requiring precise control and regulation. It is designed so that it can run without the need for synchronization, which provides convenience for some specific application scenarios
