Product Description
The Woodward 8280‑192 is part of the ProTech‑GII safety and protection system family, engineered for overspeed protection and digital speed control in turbines and large rotating machinery. It continuously monitors shaft speed via magnetic pickup (MPU) sensors and issues fast trip signals to turbine trip valves or breaker systems during overspeed conditions.
Designed for mission-critical industrial applications, this module features Triple Modular Redundancy (TMR) with three independent internal modules that vote to ensure reliable trip action. Therefore, even if one module fails, the system continues to provide protection.
The 8280‑192 is housed in a rugged IP56-rated enclosure, making it suitable for harsh environments with dust, moisture, and vibration. Moreover, the module integrates built-in diagnostics, LED indicators, and watchdog timers, providing operators with easy monitoring of system health. It supports 24 VDC operation, 4–20 mA analog speed readout, and high-speed digital load sharing capabilities.
