Rotor Dynamics Signal Processing Characteristics

The IS200TVIBH2BBB interfaces with turbine vibration sensors and processes dynamic mechanical signals for the Mark VI control architecture. The module supports vibration analysis using proximity probe inputs, including eddy-current probe signal conditioning and scaling functions required for shaft displacement measurement.

Signal conditioning circuits maintain channel separation and reduce cross-talk effects between vibration measurement paths. The module supports configurable vibration alert and danger thresholds for mechanical protection functions within simplex and TMR control configurations.

Field Installation Guidelines

Install the IS200TVIBH2BBB in the designated GE Mark VI rack position and verify all backplane connections before energizing the control system. Confirm sensor wiring polarity and shielding connections before connecting vibration probes.

Route vibration sensor cables separately from high-current power conductors and switching circuits to reduce electromagnetic interference. Connect cable shields according to the turbine control cabinet grounding scheme and avoid multiple ground paths.

Verify probe gap settings, sensor signal levels, and channel configuration parameters during commissioning. Inspect connectors, BNC interfaces, and terminal points for contamination or mechanical damage before operation.
