Woodward 8237-1600 Configurable Overspeed Detection System

Description

The Woodward 8237-1600 is a configurable overspeed detection system designed to safely shut down steam, gas, and hydro turbines upon detecting an overspeed or overacceleration event. It is built to provide robust protection for turbines of all sizes.

Specifications

• Dimensions: Approximately 13 x 17.5 x 6.25 inches
• Weight: Less than 23 lbs
• Power Requirements:
  • High Voltage Inputs: 115 Vac, 220 Vac
  • Low Voltage Inputs
• Environmental Ratings: IP56 (dust and water-resistant when installed properly)
• Operating Temperature: –20 to +60 °C at 95% humidity
• Storage Temperature: –20 to +65 °C at 95% humidity

Features

• Acceleration Detection: Monitors and protects turbines from high acceleration events by detecting the derivative of the speed signal.
• MPU Detection: Ensures the Magnetic Pickup Unit (MPU) is connected and functioning correctly before and during turbine operation.
• Automatic Overspeed Test Routine: Configurable to conduct routine overspeed tests and log results for maintenance and monitoring.
• Sulfur Contamination Resistant: Features a special conformal coating to protect against H2S and SO2 gases.
• On-line Repair: Employs a triple-modular design allowing for module replacement while the turbine remains operational.
• Communication Interfaces: Includes Modbus communication for seamless integration into existing turbine systems.
