8200-1302  505D Digital Governor Turbine Controller

Product Description

The 8200-1302 is one of several Woodward 505 Digital Governors available for the control of steam turbines. This operator control panel acts as a graphical interface and keypad that allows for adjustments to and communication with the turbine. This can be configured through Modbus communication ports located on the unit.  

The 8200-1302 has multiple features available:

• Auto start sequencing for hot and cold starts, with temperature input options
• Critical speed avoidance on three-speed bands
• Ten external alarm inputs
• Ten external DI trip inputs
• Trip indication for Trip and Alarm events with associated RTC time stamp
• Dual Speed and Load Dynamics
• Peak Speed Indication for Overspeed Trip
• Zero Speed Detection
• Remote droop
• Frequency dead-band

The unit also offers three normal operating modes, including configuration, operation, and calibration modes.

The unit includes two redundant speed inputs that can accept magnetic pickup units, eddy current probes, or proximity probes. It has analog inputs (8) that can be configured for any of twenty-seven functions.   The unit also has an additional twenty contact inputs.  The first four of these contacts default for shutdown raise speed setpoint, reset, and lower speed set point.  The others can be configured as needed. Additionally, the unit has two 4-20 mA control outputs and eight Form-C relay contact outputs.

The 8200-1302’s front panel includes an emergency trip key, a backspace/delete key, a shift key, as well as view, mode, ESC, and home keys.  It also has navigation cross keys, soft key commands, and four LEDs to relate the status of control and hardware. 

For additional information regarding the use and installation of the 8200-1302, please refer to the original documentation from Woodward.
