Overview

The Woodward 9907‑345 OPS Control is part of the Woodward 9907 series of overspeed protection systems. It continuously monitors turbine or engine speed and, if an overspeed event is detected, it initiates a shutdown signal to prevent mechanical damage or catastrophic failure.

This module is widely used in power generation, oil & gas, marine propulsion, and industrial turbine applications, where overspeed protection is critical for safety and compliance with industry standards.
