Product Description
The Woodward 8237‑1597 is a ProTech‑GII overspeed protection unit engineered to provide independent, high-reliability speed monitoring for steam, gas, hydro turbines, reciprocating engines, and industrial process equipment. It continuously monitors rotor speed via magnetic pickups and triggers a fast, independent trip output when overspeed or over-acceleration events are detected.
Designed for harsh industrial environments, the bulkhead-mounted device features an IP56-rated enclosure, making it resistant to dust and water spray. Moreover, the 8237‑1597 integrates three separate internal modules that provide independent sensing and voting, ensuring modular fault tolerance and reliable overspeed detection.
Its high-voltage input (100–150 V, model-dependent) and front-panel access make it suitable for HV power systems, enabling straightforward integration into turbine safety systems. Therefore, this unit is ideal as a secondary, independent overspeed protection layer, complementing main turbine controls.
