IS200VVIBH1BBA

About the IS200VVIBH1BBA

The Vibration/Position I/O Terminal Board IS200VVIBH1BBA manufactured by General Electric in the Mark VI system is used for shaft vibration monitoring with Bently Nevada probes. The VVIB will process the associated signals when used with a TVIB board. The velocity signals and digitized displacement signals will be sent by the VME bus to the available controller. The VVIB can be connected to a Bently Nevada 3500 monitoring system to consistently and permanently monitor the vibration of the turbine. 

During the operation of the IS200VVIBH1BBA board, it will send power to the Bently Nevada velomitor, accelerometer, proximitor, and seismic probes in TMR or simplex modes. The signals received by the attached probes and TVIB board will be sent back to the VVIB board, A/D converted, then sent over the VME bus and to the controller. Axial position alarms, trip logic, eccentricity, and vibration will be generated within the controller. 

Some features available on the IS200VVIBH1BBA model are rotor axial position, vibration monitoring/analysis, probes, and more. The vibration monitoring/analysis feature is used to actively isolate the inputs and make the signals available through four plugs for direct cabling to a Bently Nevada 3500 monitor. Maximum reliability will be provided through the configuration of the Bently Nevada monitor. For more information on the above features, refer to the GEH-6421 System Guide and the appropriate datasheet.
