Woodward 8237-1600 ProTech-GII Overspeed Protection Device with module 5437-1124
Description:
8237-1600 is designed as Woodward ProTech-GII—Panel Mount Overspeed Protection Device. 

The ProTech-GII is an overspeed safety device designed to safely shut downsteam, gas, and hydro turbines of all sizes upon sensing an overspeed or over-acceleration event. This device accurately monitors turbine rotor speed andacceleration via active or passive MPUs (magnetic pickups) and issues ashutdown command to the turbine's trip valve(s) or corresponding trip system.

The ProTech-GII includes Overspeed and Over-acceleration functions as well astime stamped Alarm, and Trip logs. Indication that a test was active at the time ofthe event is provided on all logs and first-out indications are provided for Triplogs. The ProTech-GII also provides various pre-defined test routines includingan automated periodic test routine to assist users with verifying systemoperation.

Applications:
8237-1600 can be applied as an overspeed device for any sizesteam, gas, or hydro turbine, reciprocating engine, or plant process equipment.The device's fast response time (8–26 milliseconds depending on model andconfiguration), 0.5 to 32 000 rpm speed range, and integrated overspeed andacceleration detection/protection functionality, make it ideal for application oncritical low-speed or high-speed rotating motors, compressors, turbines orengines. This device accepts one speed (MPU or PROX) input per module(3 total). In addition to the trip relay outputs, each ProTech-GII module providesone relay output that is dedicated to an alarm function (3 total) and one analogspeed output (3 total). 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 orwithin an IEC61511-based plant safety system.
