GE IS200TVIBH2BBB Vibration Terminal Board for Mark VI Turbine Control

The GE IS200TVIBH2BBB is a Vibration Terminal Board in the Mark VI control system, critical for vibration monitoring in industrial machinery. It connects up to 14 Bently Nevada probes 2 of which can link to the VVIB board for further processing and supports diverse probe types: proximity, velocity, acceleration, seismic, and phase.

Working with the Vibration Input Vector Board, it facilitates continuous vibration monitoring. The VVIB supplies power (-28V DC, with redundancy via diode high-select circuits in TMR systems) and processes signals through analog-to-digital conversion, transmitting data via the VME bus to the controller. The controller generates alarms for vibration, eccentricity, axial position and trip logic to prevent failures. It includes BNC connectors for portable maintenance tools, enabling predictive checks.

Features:
Probe Compatibility: Supports 14 Bently Nevada probes and integrates with VVIB for advanced signal processing.

Redundant Power: -28V DC from VVIB, with TMR systems using diode high-select circuits for reliable power; regulators provide -23 to -26V DC with short-circuit protection.

Signal Processing: Probe signals undergo A/D conversion via VVIB, with high-speed sampling for real-time data transmission to the controller.

Maintenance & Safety: BNC connectors enable portable data gathering; controller-generated alarms/trip logic prevent machinery failures.

System Integration: Seamless with Mark VI, enhancing operational efficiency by minimizing downtime through proactive vibration monitoring.
