WOODWARD 8237-1600 ProTech-GII HV/LV Panel Module

Overview

The WOODWARD 8237-1600 ProTech-GII is a sophisticated overspeed safety device designed to protect steam, gas, and hydro turbines by providing rapid shutdown in the event of overspeed or over-acceleration. With its advanced 2-out-of-3 voting logic and redundant architecture, the ProTech-GII ensures that unsafe conditions are detected and acted upon without risk of single-point failure. It is widely used in critical applications to maintain both personnel safety and system uptime.

Key Features

• Overspeed & Over-Acceleration Protection: The ProTech-GII monitors turbine rotor speed and acceleration, instantly issuing a shutdown command to prevent damage.

• Independent or Voted Outputs: Trip outputs are either independent or configured in a 2-out-of-3 voting scheme, ensuring high reliability.

• Multiple Interfacing Options: Front panel access for monitoring and configuration, Modbus interface for remote data access, and a Programming and Configuration Tool (PCT) for PC-based management.

• Time-Stamped Logs: Includes Alarm and Trip logs with time stamps and first-out indications, ensuring full event traceability.

• Test Routines: Predefined test routines, including an automated periodic test, to verify proper system operation.
