Description
Product Description
The 8200-1302 WOODWARD digital speed controller is used to control the speed of equipment to meet specific operational requirements.
feature
Featuring modular design,it facilitates users to add or modify modules according to application requirements.
Equipped with communication interfaces,it can communicate with other control systems and devices,achieve data exchange and remote monitoring.
Highly stable design ensures reliable operation of equipment.
Some models have self diagnostic functions,which can detect equipment problems and provide relevant information for easy maintenance and repair.
8200-1302 is one of the various Woodward 505 digital governors that can be used to control steam turbines.The operator control panel serves as a graphical interface and keyboard,allowing for adjustments to the turbine and communication with the turbine.This can be configured through the Modbus communication port on the device.
8200-1302 has multiple available functions:
Automatic start sequence for hot start and cold start,with temperature input options
Avoiding critical speeds on the three speed belt
Ten external alarm inputs
Ten external DI trip inputs
Trip indication for trip and alarm events with relevant RTC timestamps
Dual speed and load dynamics
Peak speed indication for overspeed trip
Zero speed detection
Remote droop
Frequency dead zone
The device also provides three normal operating modes,including configuration,operation,and calibration modes.
This device includes two redundant speed inputs and can accept magnetic pickup devices,eddy current probes,or proximity probes.It has analog inputs(8)and can be configured as any of the 27 functions.The device also has an additional 20 contact inputs.The first four of these contacts are used by default for closing,raising speed settings,resetting,and lowering speed settings.Others can be configured as needed.In addition,the device also has two 4-20 mA control outputs and eight C-type relay contact outputs.
The front panel of 8200-1302 includes emergency trip keys,backspace/delete keys,Shift keys,as well as view,mode,ESC,and Home keys.It also features navigation cross keys,soft key commands,and four LEDs for associating control and hardware status.
application area
The 8200-1302 WOODWARD digital speed controller is mainly used in industrial automation and control fields such as power generation,petroleum and natural gas,chemical industry,papermaking,food and beverage,etc.
