🌐 Woodward 8237-1369 ProTech GII, TPS, and MSM Overspeed Protection Module
The Woodward 8237-1369 ProTech GII is an advanced, triple modular redundant (TMR) overspeed protection system engineered for industrial turbines and critical rotating machinery. Designed with superior reliability and response speed, it ensures the highest level of machine safety while providing continuous monitoring and diagnostic capability. This module belongs to the ProTech GII series, known for its redundant design, flexible configuration, and integration compatibility with turbine control systems such as TPS (Turbine Protection System) and MSM (Mechanical Speed Monitoring).
⚙️ Technical Overview
The 8237-1369 unit offers precise speed detection and immediate shutdown protection in case of overspeed events. It employs three independent speed-sensing channels, each equipped with its own microprocessor, power supply, and input signal conditioning circuit. The TMR architecture ensures that a single-channel fault will not compromise overall system performance, making it ideal for mission-critical operations in power generation, petrochemical, and marine turbine systems.

This ProTech GII variant, with part number 8237-1369, is engineered for environments requiring high integrity overspeed protection and operational continuity. Its triple modular architecture and redundant trip outputs ensure compliance with the most stringent international safety standards.
🛠️ Installation and Maintenance
Installation involves mounting the panel enclosure in a control cabinet or equipment rack. Each sensing channel connects to its respective speed pickup via shielded cable. Power and relay wiring should follow Woodward’s standard wiring diagrams to maintain signal integrity. Periodic testing using the built-in trip test function is recommended to verify proper relay operation and ensure continued protection reliability.
Routine maintenance is minimal—operators should perform visual inspection, signal verification, and firmware diagnostics quarterly or as part of regular turbine maintenance cycles. Firmware updates and system calibration can be performed through the onboard configuration interface.
