Description
The WOODWARD 9907-167 controller is a digital control device designed specifically for steam turbine control. This controller is part of the 505E series produced by Woodward Corporation in the United States and is one of the oldest independent turbine control system manufacturers in the United States.
The working principle of the 9907-167 controller is to use a pair of actuators to drive the inlet valve, thereby causing the turbine to operate. The device is equipped with a 32-bit microprocessor for controlling the turbine. In addition, it also consists of a series of printed circuit board devices installed in an enclosure that can be safely installed within the control panel system.
This controller can be equipped with a NEMA 4X level protective casing, which is optional, but it can effectively protect electromechanical components from any permanent damage or any invasive particles. Without a protective frame, the ambient temperature range of the 9907-167 device is -25 to 65 ° C, but with a frame, it can only withstand an ambient temperature of up to 55 ° C.
It should be noted that for specific operations or use of this controller, it is recommended to consult experts in the relevant field or refer to relevant user manuals and documents.
