8200-1302 is one of several Woodward 505 digital speed controllers that can be used for controlling steam turbines. The operator control panel serves as a graphical interface and keyboard, allowing for adjustment and communication of the turbine. This can be configured through the Modbus communication port on the device.

8200-1302 has multiple 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.

The device includes two redundant speed inputs and can accept magnetic sensors, eddy current probes, or proximity probes. It has analog inputs (8) and can be configured for any of the 27 functions. The device also has an additional 20 contact inputs. The first four of these contacts default to the shutdown increase speed setting, reset, and lower speed setting. Others can be configured as needed. In addition, the device has two 4-20 mA control outputs and eight Form-C relay contact outputs.

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