GE IS200TVIBH2BBB Turbine Vibration Input/Output Module
The GE IS200TVIBH2BBB, also cataloged as the IS200TVIB Turbine Vibration Input/Output Module, operates as a dedicated hardware component for vibration signal acquisition and mechanical condition monitoring within the GE Mark VI Speedtronic Turbine Control System. The module processes proximity probe, velocity sensor, accelerometer, seismic, and phase reference signals.
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.
Frequently Asked Questions
Q: What sensor types can be connected to the IS200TVIBH2BBB module? A: The module supports proximity probes, velocity sensors, accelerometers, seismic sensors, and phase reference probes for turbine vibration monitoring.
Q: Does the module provide isolated vibration signal processing channels? A: The module uses ground isolation and EMI/RFI shielding methods to reduce interference between vibration signal channels.
Q: What vibration signal sampling capability is provided by the module? A: The module supports sampling rates up to 20 kS/s per channel with a minimum 16-bit signal resolution.
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.
