Woodward 5437-1067A Overspeed Safety Device for Turbines

The Woodward 5437-1067A Overspeed Safety Device for Turbines is a high-reliability module of the Woodward ProTech GII series, part of Woodward's SIL-3 overspeed protection system. It is designed to monitor and protect steam, gas and hydro turbines against catastrophic overspeed and over-acceleration events. As an overspeed safety device, it continuously measures turbine speed, detects dangerous acceleration, and triggers protective shutdown before machine limits are exceeded — a dedicated protection channel independent of the turbine governor.

Woodward 5437-1067A Overspeed Safety Device for Turbines is the overspeed protection module that watches turbine speed independently from the control loop: it detects overspeed and excessive acceleration on steam, gas or hydro turbines and acts to bring the machine to a safe stop before mechanical limits are reached. Its place in the ProTech GII SIL-3 system means protection is handled by a dedicated, high-reliability path, supporting fail-safe turbine shutdown philosophy.
