Woodward’s 8200-1300 provides digital control for steam turbines. It is one of several digital governors available in the 505 turbine control series. The unit uses a standard LVDC (18-32 VDC) power supply.

The device can be used in non-hazardous places. It is also available for Class I Zone 2 A/B/C/D group locations. The unit is usually fitted with stranded copper field wiring with a temperature rating of at least 75 degrees Celsius.

The 8200-1300 can control steam turbines with single or double shunt range actuators. It can be configured as part of a factory DCS (Distributed control System) or used as a stand-alone unit. It is designed with five PID controllers, including a speed/load PID controller, a cascade PID controller, and AUX1 and AUX2 PID controllers. The unit provides an operator control panel comprising a graphic control panel display and keyboard. The panel includes an emergency stop button, start, stop, esc, and home buttons, a numeric keypad and toggle up/down buttons, and an Enter key with up/down and left/right buttons. There are also four leds on the left side of the panel, including CPU health, IO lock, Summary Alarm, and Summary Trip.

Internally, the 8200-1300 includes a watchdog timer and a CPU failure circuit to monitor the operation of the microprocessor and its memory.
