GE IS200TVIBH2BBB – Vibration Input Terminal Board for Mark VI/Mark VIe Systems

The GE IS200TVIBH2BBB is a vibration input terminal board designed for the Mark VI/Mark VIe control platform. From my experience, it’s the go-to field-wiring interface when you’re tying eddy-current proximity probes or seismic/velocity sensors into a GE turbine control panel. It appears to be a passive board with robust surge suppression and channel-by-channel conditioning components, making it a practical swap for aging vibration wiring blocks without reworking your cabinet layout.

Typical use cases include gas and steam turbine bearing vibration, shaft position/expansion pickups, and general machine protection inputs. One thing I appreciate is how the TVIB series usually keeps wiring clean—clearly labeled terminals, shield termination points, and a simple ribbon connection back to the processing card. A maintenance supervisor told us, “We replaced a mixed set of older terminals with TVIB and cut our outage wiring checks by almost half,” which matches what I’ve seen on retrofits.

Key Features

• Multi-channel vibration inputs – supports multiple proximity probe or velocity sensor channels for bearing vibration and shaft position monitoring.
• Passive terminal design – no separate power feed; simplifies replacement and reduces points of failure.
• Conditioning and protection – channel surge suppression and filtering components help stabilize signals in noisy turbine environments.
• Ribbon interface to processor – quick connect to the associated vibration processing board in the Mark VI/Mark VIe rack.
• Shielding and grounding provisions – proper earthing points typically included to minimize ground loops.
• Service-friendly layout – labeled terminals and test access that make commissioning and troubleshooting faster in many cases.

Technical Specifications

Related or Supporting Products

• IS200VTUR series vibration/turbine processing board – mates via ribbon cable and performs signal acquisition/processing from TVIB inputs.
• IS200TVIBH1 variants – earlier hardware revisions with similar channel count; H2 typically refines noise immunity and terminal layout.
• IS200TACHH1 tachometer terminal board – complementary for speed pickups; often installed alongside TVIB in turbine panels.
• IS215VCMIH2 controller interface board – system communication backbone in many Mark VI installations.

Installation & Maintenance

• Cabinet environment – install in a clean, dry control cabinet; keep ambient within 0–60 °C and allow modest airflow around terminal blocks.
• Wiring practices – use shielded twisted-pair for probe leads; ground shields at the designated TVIB point only to avoid loops.
• Separation – route vibration signals away from high-voltage and fast-switching motor cables; maintain proper segregation and tie-down.
• Connections – tighten terminal screws to manufacturer torque; verify ribbon connector latch to the processing board before power-up.
• Routine checks – periodically inspect terminals for loosened screws, oxidation, or insulation damage; clean with ESD-safe methods.
• Calibration workflow – sensor calibration is performed at the probe/proximitor or in the processor; TVIB is passive, but re-verify channel integrity after any field work.
• Firmware – no firmware on the terminal board; keep the paired processor board updated per site standards.

Quality & Certifications

• Manufactured under ISO 9001 quality systems (typical for GE industrial controls)
• CE and UL conformity generally applicable to the complete Mark VI control system
• RoHS applicability varies by production lot and region; many units meet RoHS criteria for spare parts
• Standard manufacturer warranty coverage: 12 months
