Woodward 8237-1600 Overspeed Safety Device

Description

The Woodward 8237-1600 is an overspeed safety device designed to safely shut down steam, gas, and hydro turbines of all sizes upon sensing an overspeed or overacceleration event. It features a panel mount design with high voltage/low voltage power input and voted relays/voted inputs for steam turbine overspeed protection.

Features

• Acceleration Detection: Protects turbines from high acceleration events by detecting the derivative of the speed signal and issuing a trip command.
  
• MPU Detection: Validates the MPU connection before and during turbine operation.
  
• Automatic Overspeed Test Routine: Performs routine overspeed tests and logs the results.
  
• Sulfur Contamination Resistant: Utilizes a special conformal coating material for long-term protection against H2S and SO2 gases.
  
• On-line Repair: Allows for easy replacement of modules while the turbine is operating.
  
• Modbus Communications: Integrates easily into any turbine safety system.
