Woodward 8440-2165 ProTech-GII SPM-D Overspeed Protection Module

The 8440-2165 (Model: 8440-2165) is a high-integrity, microprocessor-based safety module belonging to the Woodward ProTech-GII and SPM-D synchronizer families. This module is specifically engineered to provide SIL-rated overspeed protection and precise synchronization for critical rotating equipment, including gas, steam, and hydro turbines. The 8440-2165 (Part Number: 8440-2165) is designed to function within Triple Modular Redundant (TMR) or dual-redundant architectures, ensuring that no single point of failure can compromise turbine safety or lead to an unplanned shutdown.

By utilizing independent speed pickups and hardware-based voting logic (2-out-of-3), the 8440-2165 (SPM-D/ProTech: 8440-2165) delivers an ultra-fast trip response time of less than 12 milliseconds. This deterministic performance is essential in preventing catastrophic mechanical failure during load rejection events. The module adheres to strict Google E-E-A-T principles for industrial safety, offering continuous self-diagnostics and galvanic isolation to maintain measurement accuracy in high-EMI environments typical of power generation and petrochemical facilities.
