WOODWARD 8237-1600 ProTech-GII Overspeed Protection Module

    This overspeed protection module serves as a critical safety component for steam, gas, and hydraulic turbines in demanding environments. Designed to prevent catastrophic failures during over-speed or over-acceleration events, it combines advanced diagnostics with triple modular redundancy to ensure continuous operational safety across energy, oil & gas, and industrial sectors.

    Engineered for harsh environments, this module withstands corrosive gases like H2S and SO2 through its anti-sulfur conformal coating. The 4–20 mA speed signal output enables precise turbine monitoring, while Modbus® communication simplifies integration with existing control systems. One of our clients in offshore gas operations specifically praised its “3-out-of-2 voting architecture” for reducing false trips during pipeline pressure fluctuations.

    Common applications include retrofitting legacy turbine systems in power plants, protecting gas compression units in LNG facilities, and safeguarding hydraulic turbines in paper mills. We’ve supplied this module for compatibility with systems like:

• WOODWARD 8521-0312 UG-10D controllers
• 8440-1713/D position control systems
• 9907-162 digital control modules

    Our inventory includes both new and refurbished units with full 1-year warranties. For example, a recent batch of 8237-1600 modules for a Texas-based petrochemical plant included pre-installation calibration to API 670 standards. If you’re working on turbine upgrades or emergency replacements, we can often ship within 24 hours from our Houston warehouse.
