GE IS200TVIBH2B Vibration Terminal Board Mark VI

Description

Product Introduction & Engineering Value

The IS200TVIBH2B is a GE Mark VI vibration terminal board used to terminate and route vibration-related signals between field devices and the control system. It is particularly important where turbine vibration monitoring forms part of the operating or protection scheme. The board is identified as a VVIB-compatible termination board rather than a general-purpose analog I/O module.

One detail matters during replacement: do not select a substitute simply because the board carries the same “TVIB” designation. The IS200TVIBH2B has specific compatibility requirements within the Mark VI architecture. GE-related references specifically identify the VVIB board as its compatible counterpart.

Technical Specifications

The available technical references are not fully consistent on channel count, electrical ranges, and sample-rate figures. Some third-party listings describe the board as having 13 or 14 vibration connections, while others publish generic 16-channel analog specifications. Those figures should not be treated as authoritative without checking the exact board revision and GE documentation.

The more reliable identification points are the TVIB function, Mark VI architecture, VVIB compatibility, jumper configuration, and vibration termination role.

Field Application & The “Trench” Experience

A turbine maintenance team discovers intermittent vibration alarms after replacing a damaged termination board during a scheduled outage. The replacement initially appears correct because the IS200TVIBH2B part number is present on the board label. The problem appears only during loop verification: several vibration channels do not behave as expected.

The technician checks the wiring first. Nothing obvious is wrong. The next step is comparison against the removed board, including revision markings, jumper positions, terminal assignments, and the associated VVIB configuration. That comparison reveals the real issue: the termination hardware cannot be treated as a generic analog interface.

This is the kind of replacement where part-number verification must happen before wiring begins.

Niche application scenarios

1. Gas turbine bearing vibration monitoring — termination and routing of vibration probe signals used by the Mark VI turbine control architecture.
2. Steam turbine shaft vibration supervision — maintaining the signal path between field vibration instrumentation and the turbine control system.
3. TMR turbine protection architecture — one TVIB board can be associated with multiple VVIB boards in the appropriate Mark VI configuration.

Transparency SOP: QA & Testing

For New Surplus or Refurbished IS200TVIBH2B inventory, a credible inspection process should include:

1. Part-number verification — confirm IS200TVIBH2B and revision markings against the purchase requirement.
2. Visual inspection — examine the PCB, terminal hardware, connectors, jumper locations, components, and solder joints for physical damage or contamination.
3. Configuration check — record jumper positions before installation and compare them with the removed board or approved system documentation.
4. Electrical inspection — check for obvious shorts, damaged components, abnormal resistance paths, and power-related faults where the available test setup permits.
5. Functional verification — where test equipment and the applicable Mark VI hardware are available, verify the board’s expected signal-interface behavior.
6. Final QC — document condition, identification markings, test status, and packaging before shipment.

New Surplus does not automatically mean factory-fresh with an untouched production history. For procurement purposes, ask for the exact condition designation, board photographs, revision information, and test policy before issuing a purchase order.

The Veteran’s Tech Trap Guide

⚠️ Trap #1 — Confusing TVIB with a generic vibration input card

The is a termination board. It should not be selected as a drop-in replacement for every GE vibration-related board. Its architecture is tied to the appropriate VVIB interface.

⚠️ Trap #2 — Ignoring jumper positions

References identify 16 jumper switches on the board. Record the configuration of the existing board before removing it. A replacement with the same part number can still create commissioning problems if the installation configuration is not reproduced correctly.

⚠️ Trap #3 — Trusting a supplier’s generic specification table

This model is frequently described inconsistently online. Published channel counts and electrical specifications vary significantly between vendors. Do not approve a replacement based on a supplier’s generic “16-channel, 0–10 V” description alone. Verify the actual GE part number, revision, system architecture, and associated VVIB hardware.

PRO TIP: Photograph the old board before disconnection. Capture the full part number, revision, terminal wiring, jumper positions, and connector locations. Five minutes of documentation can prevent hours of turbine-control troubleshooting.

Dynamic FAQ

Q1. What is the GE IS200TVIBH2B?

The IS200TVIBH2B is a GE Mark VI vibration terminal board used for vibration signal termination and interfacing within the turbine control system. It is specifically associated with the VVIB board.

Q2. Is the IS200TVIBH2B compatible with the VVIB board?

Yes. The VVIB is the specifically identified compatible board for the IS200TVIBH2B in the Mark VI/Mark VIe architecture.

Q3. Can the IS200TVIBH2B be used in a TMR system?

Yes. GE-related technical references indicate that the TVIB board can be used in Mark VI Simplex and TMR configurations. In a TMR arrangement, a single TVIB can be associated with three VVIB boards.

Q4. Does the IS200TVIBH2B require calibration?

Available references indicate that the board has no potentiometers and does not require conventional field calibration. Configuration through its jumper switches still needs to match the intended system installation.

Q5. Is a New Surplus IS200TVIBH2B the same as a new OEM board?

Not necessarily. New Surplus normally refers to unused excess inventory rather than a current factory-direct purchase. Procurement should confirm physical condition, date/traceability information where available, revision, packaging, test status, and warranty with the supplier.

Q6. What warranty should I request for an IS200TVIBH2B?

Warranty terms depend on the supplier and stock condition. For a critical turbine-control spare, request the warranty period in writing and confirm what it covers. A practical purchase specification should also require the exact IS200TVIBH2B part number and revision to be verified before shipment.

Procurement Note

For a turbine outage or emergency replacement, the full identification string matters. Before ordering, verify the board label, revision, associated VVIB hardware, system topology, jumper configuration, and physical condition. Do not rely on a supplier’s generic specification sheet when conflicting technical data is published.

GE references identify IS200TVIBH2B as a Vibration Termination Board within the Mark VI/Mark VIe family, while current surplus-market listings confirm that the part is still traded as unused, open-box, or rebuilt inventory.
