Functional Overview
The IS200VVIBH1CAC functions as the vibration processing hub within the Mark VI/VIe system, receiving raw sensor signals from TVIB/DVIB terminal boards. It digitizes analog vibration and displacement signals, processes MPU pulse signals for speed and phase measurement, and analyzes data to detect abnormal vibration patterns, bearing wear, or shaft misalignment. The processed vibration data is transmitted to the main turbine controller for real-time monitoring, alarm generation, and trip initiation if parameters exceed safe thresholds. Redundant power inputs and TMR-compatible design ensure continuous operation during faults, while onboard diagnostics and LED indicators simplify troubleshooting. All connections are made via VMEbus and front-panel I/O connectors, enabling easy integration, maintenance, and system expansion。
