IS200VVIBH1C - VVIB Vibration Monitor Board | GE Mark VI | B7B

The General Electric IS200VVIBH1C (VVIB) is a Vibration Monitor board for GE SPEEDTRONIC™ Mark VI turbine control systems, processing vibration probe signals from an IS200TVIB or DVIB terminal board. Up to 14 probes connect directly to the terminal board, with up to two TVIB boards cabled to a single VVIB.

VVIB digitizes vibration signals and sends them over the VME bus to the controller. The Mark VI system uses Bently Nevada probes (proximity, velocity, acceleration, seismic, and phase types) for shaft vibration monitoring, supporting protective functions including radial vibration, rotor axial position (thrust bearing wear), differential expansion, and rotor eccentricity.

For maintenance and procurement teams, IS200VVIBH1C should be matched to the existing TVIB terminal board and redundancy configuration per GEH-6421 Volume II before ordering a replacement.

Control system parts are provided by GTC Control Solutions, Inc., a wholly owned subsidiary of B7B. Parts are offered in unused, repaired, or remanufactured condition, subject to availability. Each repaired or remanufactured component undergoes functional testing in energized panels, with test reporting and warranty support provided for repair and lifecycle-extension programs.
