IS200VVIBH1BBA | General Electric Vibration/Position I/O Board

Description 

The IS200VVIBH1BBA Vibration/Position I/O Terminal Board, manufactured by General Electric for the Mark VI system, facilitates shaft vibration monitoring using Bently Nevada probes. When utilized with a TVIB board, the VVIB processes associated signals, including velocity and digitized displacement, transmitting them via the VME bus to the controller. This board enables connection to a Bently Nevada 3500 monitoring system for continuous turbine vibration monitoring. 

During operation, the IS200VVIBH1BBA provides power to Bently Nevada velomitors, accelerometers, proximitors, and seismic probes in TMR or simplex modes. Signals from these probes, along with those from the TVIB board, undergo A/D conversion before transmission over the VME bus to the controller. The controller generates axial position alarms, trip logic, eccentricity, and vibration data based on received signals.
