GE IS200TVIBH2B Vibration Terminal Board

The GE IS200TVIBH2B, also cataloged as the IS200TVIBH2B vibration terminal board, serves as the primary terminal interface used to execute vibration‑probe signal routing across Mark VI platforms. The board provides passive wiring termination for displacement, velocity, acceleration, seismic, and phase probes feeding VVIB acquisition modules.

Hardware Specifications

Eddy‑Current Probe Scaling and Rotor‑Dynamics Signal Handling

As a Mark VI vibration interface, the TVIB board supports Bently Nevada probe behavior including:

• Eddy‑current probe scaling — displacement probes operate around a nominal −10 V DC gap voltage, enabling linearized shaft‑motion interpretation.
• Gap voltage validation — wiring paths maintain stable reference voltage to prevent drift in proximitor output.
• Rotor dynamics — terminal routing preserves low‑noise transmission of shaft‑vibration signatures for VVIB digitization.
• Cross‑talk suppression — separation of probe wiring reduces induced coupling between adjacent channels.

Frequently Asked Questions (FAQ)

Q: Can the IS200TVIBH2B be hot‑swapped? A: Terminal boards can be replaced on an energized panel, but probe wiring must be isolated to avoid transient vibration‑fault indications.

Q: How many probes can be wired directly to the board? A: Up to fourteen probes may be wired to the terminal blocks; two may be routed to VVIB via cabling.

Q: How are probe types selected? A: Jumpers JP1–JP8 configure the first eight channels for displacement, velocity, acceleration, seismic, or phase probe types.

Field Installation Guidelines

• Wire each probe using three conductors; maintain shielding continuity and bond drain wires at one end only.
• Keep proximitor cables separated from high‑current conductors to reduce noise coupling.
• Verify jumper settings (JP1–JP8) before energizing to ensure correct probe‑type identification.
• Optional connectors JA1, JB1, JC1, JD1 may be used for Bently Nevada system integration; ensure proper seating.
• Maintain clean terminal surfaces; contamination can introduce micro‑volt level noise into displacement signals.
• Avoid sharp bend radii on probe cables to prevent impedance changes affecting rotor‑dynamic measurements.
