8404-067 ProTech-GII Triple-Redundant Turbine Safety Controller

Description

TheWoodward 8404-067 ProTech-GIIis atriple-redundant overspeed protection systemdesigned for critical turbine applications. It continuously monitors rotor speed and acceleration, ensuring a safe shutdown during overspeed or unsafe operating conditions. This system is ideal forsteam,gas, andhydro turbinesin high-availability environments, where reliability and safety are paramount. ProTech-GII operates withthree independent modules (A, B, and C)and offers configurable2-out-of-3or3-out-of-3 voting logic. Each module receives input frommagnetic pickupsand controlstrip relaysto initiate a safe shutdown if thresholds are exceeded. The system also supportsonline testing and repair, allowing maintenance without interrupting turbine operation. ItsModbus RTUcommunication and4-20 mA outputsfacilitate seamless integration into plant control systems. Designed for harsh industrial environments, the 8404-067 is housed in anIP56-rated cabinet, providing protection against dust, moisture, and other environmental factors. Engineers rely on itsfault tolerance,diagnostic capabilities, and compliance withCEandUL standardsto ensure asset protection and operational safety.
