9662-610 | Woodward Industrial Digital Safety Termination Panel

Product Description

The Woodward 9662‑610 Termination Board is a high-reliability safety module designed for steam turbines, gas turbines, and other industrial prime movers. It ensures overspeed protection and emergency shutdown through a robust, triple modular redundant (TMR) architecture, meeting IEC 61508 SIL‑3 safety standards.

This digital safety module continuously monitors turbine speed and provides rapid trip signals when unsafe conditions occur, protecting equipment and personnel from catastrophic failures. Moreover, it integrates seamlessly with modern supervisory systems via Modbus RTU/TCP and Ethernet, enabling event logging, diagnostics, and predictive maintenance.

The 9662‑610 is widely implemented in power generation, petrochemical plants, and industrial process facilities, where turbine safety and operational reliability are critical. Its rugged design tolerates harsh industrial conditions and a wide operating temperature range, ensuring consistent performance.
