Woodward 8237-1600 ProTech-GII TMR Overspeed Detection Device

The 8237-1600 (Model: 8237-1600) is a premier digital overspeed protection panel within the Woodward ProTech-GII family, specifically engineered for mission-critical turbine safety. This device provides high-integrity monitoring of turbine rotor speed through a Triple Modular Redundant (TMR) architecture. The 8237-1600 (Part Number: 8237-1600) utilizes three independent channels to process signals from magnetic pickups (MPUs), employing a 2-out-of-3 (2oo3) voting logic to initiate an emergency trip. This ensures that no single point of failure—whether a sensor, wire, or internal component—can cause a nuisance trip or prevent a legitimate safety shutdown.

Designed to meet stringent SIL-rated safety standards, the 8237-1600 (ProTech-GII: 8237-1600) delivers an ultra-fast trip response time of less than 12 ms. This rapid execution is vital for protecting gas turbines, steam turbines, and large compressors from the catastrophic mechanical failure associated with overspeed events. With its IP56-rated enclosure and redundant 24 VDC power inputs, this device is built for continuous 24/7 operation in the most demanding turbine skid and industrial environments.
