Woodward 9907-164 Product Introduction

The Woodward 9907-164 is part of the 505 and 505E microprocessor-based governor control unit,specifically designed to operate steam turbines,turbogenerators,and turboexpander modules.It utilizes the turbine’s staged actuator(one or both)to drive the steam inlet valve and controls the turbine by operating a single extraction and/or intake of the turbine.

Product Features

High flexibility:Like any 505 governor module,the Woodward 9907-164 can be configured in the field by a field operator.The menu-driven software is controlled and changed by an operator control panel integrated into the front of the unit,which displays two lines of text with 24 characters per line.

Multiple Input Interfaces:The Woodward 9907-164 is equipped with a range of discrete and analog inputs,including 16 contact inputs(4 dedicated and 12 programmable)and 6 programmable current inputs ranging from 4 to 20 mA.

Standard Functions:In addition to basic control functions,the Woodward 9907-164 also has a series of standard functions such as critical speed avoidance,valve limiter,automatic start sequence and shutdown first-out indicator.These functions ensure that the module is ready for emergency shutdown when starting an engine,turbine or other type of prime mover to prevent personal injury caused by loss of control or overspeed.

High-precision control:The Woodward 9907-164 uses advanced digital microprocessor technology to achieve precise control of parameters such as fan speed and load.

Communication Interface:Supports a variety of communication interfaces,such as serial communication(RS-232,RS-485),Ethernet or fieldbus protocols(Profibus,Modbus),which facilitates data exchange and remote monitoring with other devices.

Application Scenarios

Woodward 9907-164 is widely used in industrial control systems,especially in control systems involving steam turbines,turbo generators and turbo expanders.It can serve as a key control component to ensure the stable operation and efficient performance of these equipment.
