8237-1246 ProTech-GII Series overspeed safety device

Model 8237-1246 is part of the Woodward ProTech-GII Series. It is an over-speed detection system that configures to work with multiple types of turbines. It can safely shut down hydro, steam, and gas turbines if it senses they are overaccelerating. In addition to acceleration detection, it also has MPU detection. Model 8237-1246 is also resistant to sulfur and H2S and SO2 gases. It has a triple modular design, making it easy to replace one part with the product in operation.

Additional specifications for this safety detection module include;

  • Three independent non voted trip relay outputs.
  • 4-20 mA speed readouts.
  • Low voltage and high voltage power input.
  • 2 out of 3 voted architecture.
