The IS200TVBAH2ACC is a vibration input terminal board designed for the General Electric Mark VI and Mark VIe Speedtronic turbine control systems. This board acts as a critical field wiring interface, facilitating the connection between various vibration monitoring sensors and the system's I/O packs. It is engineered to perform essential signal conditioning, including buffering and filtering, to ensure accurate data transmission for turbine protection and analysis.

Features

• Supports diverse vibration sensor types, including eddy current proximity probes, seismic velocity transducers, and accelerometers.
• Provides signal termination, biasing, and buffering for stable performance in high-noise industrial environments.
• Equipped with conformal-coated PCB to enhance durability against moisture, dust, and corrosive gases.
• Includes buffered outputs via front-edge connectors for parallel diagnostic monitoring.
• Compatible with Bently Nevada monitoring racks and other third-party diagnostic equipment.

Applications

• Gas and steam turbine health monitoring and protection.
• Compressor and generator vibration analysis.
• Rotor dynamics monitoring for large rotating machinery.
• Wind turbine drivetrain feedback systems.

Technical Specifications

Installation Guidelines

• Ensure the system is fully de-energized before installing or removing the board to prevent electrical transients or circuit damage.
• Mount the board securely on a standard DIN rail or within the designated Mark VI/VIe control cabinet panel.
• Connect field sensors to the 24-terminal blocks; terminals support wire sizes from 24 to 14 AWG.
• Terminate all cable shields directly to the provided chassis ground bus bar or shield attachment points to mitigate EMI.
• Handle the PCB with standard ESD precautions to protect sensitive electronic components.

FAQ

Can the IS200TVBAH2ACC be hot-swapped?

No. The board must be de-energized before removal to avoid damaging circuitry or creating electrical transients.

Are the buffered outputs isolated from primary control signals?

Yes. Buffered outputs via BNC and D-sub connectors are isolated, allowing for the safe connection of external diagnostic tools.

What transducers are compatible with this board?

The IS200TVBAH2ACC supports proximity probes, seismic velocity sensors, accelerometers, and Velomitor-type transducers.
