IS200TVBAH2AAA GE Module Parts Mark VI Vibration Input Terminal Board
- Receives signals from proximity probes and seismic vibration sensors.
- Supports compatible Velomitor and accelerometer connections.
- Provides input interfaces for turbine shaft vibration and position monitoring.
- Supports dynamic pressure sensor interfaces when used with compatible charge amplifiers.
- Provides transient suppression against electrical disturbances.
- Protects individual input signal paths.
- Supports sensor open-circuit detection through configured bias and current circuits.
- Routes incoming signals to the associated vibration-monitoring I/O packs.
- Provides buffered vibration signals for external monitoring equipment.
- Supports BNC connections for diagnostic instruments.
- Provides DB9 and DB25 interfaces for compatible Bently Nevada monitoring systems.
- Allows external monitoring without directly loading the original sensor signal.
- Verify the board number: Confirm IS200TVBAH2AAA and inspect its hardware revision.
- Check system compatibility: Identify the Mark VI or Mark VIe architecture and the associated vibration I/O pack.
- Inspect terminal blocks: Check the two terminal strips and field wiring connections.
- Verify sensor wiring: Confirm sensor type, polarity, cable shielding and grounding.
- Check power supplies: Verify the +28 V DC supply and the required negative sensor power arrangement.
- Configure jumpers: Set sensor power, open-circuit detection and buffered-output configurations according to GE documentation.
- Test buffered outputs: Verify BNC, DB9 and DB25 signal outputs using approved diagnostic equipment.
- Check system diagnostics: Confirm that connected I/O packs recognize the terminal board and that no sensor faults are reported.
- Perform functional testing: Compare vibration and shaft-position readings with approved reference instruments.
It is a GE Vibration Input Terminal Board (TVBA) used to interface vibration and shaft-position sensors with turbine control and monitoring systems.
The board is documented with support for up to 14 sensor connections, including vibration and position measurement inputs.
Compatible sensor types include proximity probes, seismic velocity sensors, Velomitors and certain accelerometer configurations.
