WOODWARD 9907-164 Product Overview

WOODWARD 9907-164 is a control module that integrates advanced digital microprocessor technology.It can achieve precise control of parameters such as fan speed and load,and has a wealth of control functions,including speed control,load control,compressor and turbine start and stop control,etc.In addition,the module can also collect and monitor data related to turbine performance,such as speed,temperature,pressure,etc.,to ensure that the turbine operates within a safe and effective working range.

Main Features

High-precision control

Adopting advanced digital microprocessor technology,it can achieve precise control of steam turbine speed,load and other parameters.

Rich control functions

Including speed control,load control,compressor and turbine start and stop control,etc.,to meet the control requirements under various complex working conditions.

Data acquisition and monitoring

Capable of acquiring and monitoring data related to turbine performance,such as speed,temperature,pressure,etc.,to ensure that the turbine operates within a safe and effective working range.

Communication interface

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

Self-diagnosis and fault detection

With self-diagnosis function,it can detect turbine faults and issue alarms,thereby improving the reliability and safety of the system.

Highly flexible

The field operator can configure and change the device on site through the menu-driven software integrated on the operator control panel on the front of the device.

Hardware specifications

Input interface

Includes 16 contact inputs(4 dedicated inputs and 12 programmable inputs)and 6 programmable current inputs from 4 to 20 mA.

Display and control

The operator control panel on the front of the device can display two lines of text with 24 characters per line for controlling and changing the menu-driven software.

Standard functions

Includes critical speed avoidance,valve limiters,automatic start sequence and shutdown before stop indicators to ensure emergency shutdown is prepared when starting engines,turbines or other types of prime movers to prevent personal injury due to loss of control or overspeed.

Application areas

WOODWARD 9907-164 is mainly used to operate steam turbines,steam turbine generators and turbo expander modules,and is suitable for a variety of industrial occasions that require high-precision control and reliable operation.

Additional software functions(OpView™and 505View)

WOODWARD 9907-164 also provides two human-machine interface(HMI)software packages:OpView™and 505View.Both software packages are self-configuring and do not require field engineering because they automatically configure the screen to match the programming application of the control.They have the following common features

Automatic screen generation based on control configuration.

Real-time trend function(505View also includes historical trend function).

Logging function of event status(505View also includes historical record function).

Security,with multiple user levels.

Remote access capability(only available in 505View).

Alarm/trip status indication and time-stamped alarm/trip log.
