The Woodward 8200-203 is an electronic overspeed protection system manufactured by Woodward Governor Company. It is a critical safety component used in a variety of applications to prevent engines, turbines or other rotating machinery from exceeding safe operating speeds.

Main functions:

Speed monitoring: The 8200-203 continuously monitors the speed of the prime mover (e.g. engine, turbine) using three independent speed sensing units.
Overspeed detection: When the speed exceeds a preset threshold (usually a percentage of the maximum rated speed), the system triggers an alarm and initiates a trip sequence.
Stroke operation: Stroke operation may involve:
Disconnect the fuel supply to the engine or turbine.
Close the valve to stop the flow of working fluid (e.g. water, steam).
Activate the alarm system to alert the operator.
Enable additional protection measures defined in the system configuration.
Applications:

The Woodward 8200-203 is commonly used in a variety of applications where overspeed protection is critical to safety and reliability:

Gas turbine engines: Protect gas turbines used for power generation, aviation and Marine propulsion.
Steam turbines: Ensure the safe operation of steam turbines in power plants and industrial applications.
Industrial machinery: protection against overspeed hazards of pumps, compressors and other rotating machinery.
