Product Overview

8237‑2600 belongs to Woodward ProTech‑GII overspeed protection series, designed for gas turbines, steam turbines and generator prime‑mover machinery. It accepts signals from magnetic pick‑up speed sensors, executes triple‑modular‑redundant voting logic to prevent dangerous overspeed conditions. It stores trip historical logs, supports local parameter setup via front panel and remote configuration through Modbus interface. Widely deployed in power generation, oil‑gas compression systems. Discontinued safety protection hardware available as refurbished and tested surplus spare parts for turbine protection cabinet overhaul.

Application Notes

‑ Install in well‑ventilated control cabinet; comply with API‑670 installation guidelines. ‑ Use shielded twisted‑pair wiring for magnetic pickup sensor circuits, separate from high‑power cables. ‑ Execute periodic function test according to site safety maintenance procedure. ‑ Typical deployment: power‑plant turbine overspeed‑protection spare‑part stocking.
