Woodward 8237-1600 ProTech-GII Overspeed Safety Device

Woodward 8237-1600 ProTech-GII Overspeed Safety Device

The 8237-1600 ProTech-GII is designed to be applied as an overspeed device for any size steam, gas, or hydro turbine, reciprocating engine, or plant process equipment. The device's fast response time (8–26 milliseconds depending on model and configuration), 0.5 to 32 000 rpm speed range, and integrated overspeed and acceleration detection/protection functionality, make it ideal for application on critical low-speed or high-speed rotating motors, compressors, turbines or engines. This device accepts one speed (MPU or PROX) input per module (3 total). In addition to the trip relay outputs, each ProTech-GII module provides one relay output that is dedicated to an alarm function (3 total) and one analog speed output (3 total). 

The ProTech-GII utilizes a triple modular redundant architecture and 2-out-of-3 voting logic to accurately determine unsafe conditions and ensure that no singlepoint failure will affect system reliability or availability. With this design, failures in overspeed system components (switches, transducers, modules) are detected, annunciated, and allowed to be repaired or replaced while the monitored system continues to operate on-line. Optionally the ProTech-GII can be configured to share and vote on all speed inputs as required by the application, The ProTechGII is designed for critical applications where both personnel safety and unit availability (operation run time) is a concern or necessity. 

The ProTech-GII is certified as an IEC61508 SIL-3 (Safety Integrity Level 3) safety device and can be applied as a stand-alone IEC61508-based device or within an IEC61511-based plant safety system.
