WOODWARD 8237-1246

The Woodward 8237-1246 module is part of the Woodward ProTech-GII family and is primarily used to detect and prevent turbine overspeed. Once the speed is detected to exceed the safety limit, the module sends a signal to trigger safety protection measures to prevent damage to the equipment. It is widely used in hydraulic, steam and gas turbines.
