Woodward 8237-1369 ProTech-GII TMR Overspeed Protection System

The 8237-1369 (Model: 8237-1369) is a high-integrity digital overspeed protection device belonging to the Woodward ProTech-GII family. This system is engineered to provide fail-safe monitoring for gas, steam, and hydro turbines, as well as large industrial compressors. Unlike traditional mechanical governors, the 8237-1369 (Part Number: 8237-1369) utilizes a Triple Modular Redundant (TMR) architecture to process speed signals from three independent magnetic pickups (MPUs). This 2-out-of-3 (2oo3) voting logic ensures that a single sensor or internal component failure will not cause a nuisance trip or, more critically, fail to trip during an actual overspeed event.

Equipped with a high-speed microprocessor, the 8237-1369 (ProTech-GII: 8237-1369) achieves a typical trip response time of less than 12 ms, providing virtually instantaneous protection for rotating assets. The unit also features automated periodic self-tests, allowing operators to verify the functional integrity of the trip relays and internal logic without taking the turbine out of service. With support for dual redundant 24 VDC power inputs and Modbus TCP/RTU communications, it is designed for seamless integration into modern plant DCS and SCADA networks.
