Product Description
The Woodward 8280‑300 is part of the ProTech‑GII safety and protection system family, designed for overspeed protection and digital control in turbines and large rotating machinery. It continuously monitors shaft speed through magnetic pickup (MPU) sensors and sends rapid trip signals to turbine trip valves or breaker systems whenever overspeed conditions are detected.
This module is built for mission-critical safety applications, featuring Triple Modular Redundancy (TMR) with three independent modules that vote to guarantee reliable trip action. Therefore, even if one module fails, the system continues to protect the machinery.
The 8280‑300 comes in a rugged IP56-rated enclosure, making it ideal for industrial environments with dust, moisture, and vibration. Moreover, the module integrates built-in diagnostics, LED indicators, and watchdog timers, allowing operators to monitor system health efficiently. It operates on 24 VDC, providing fast and reliable turbine or engine control.
