Description
The GE IS200TVBAH2ABB is a dedicated vibration terminal board designed for the Mark VI Speedtronic turbine control system that processes high-speed signals from proximity probes, seismic transducers, and accelerometers. Plant maintenance teams drop this board into their termination racks to interface directly with the VCMI and VVIB modules. Are you dealing with intermittent shaft vibration readings on a gas turbine? This board provides the physical connection points for the sensor shields, terminating up to eight channels of vibration inputs—though you should check your specific Mark VI cabinet grounding scheme to prevent ground loops from corrupting the signal.

Commercial Condition and Global Logistics Availability
We distribute this unit in Refurbished (tested) or New Surplus condition based on current warehouse availability. Because a faulty turbine protection board can trigger an emergency trip, every refurbished IS200TVBAH2ABB undergoes full-channel signal injection testing on a functional Mark VI rig before packaging.
- Availability: In stock, subject to prior sale
- Lead Time: 1 to 3 business days for final verification testing and export packaging
- Warranty: 12-month comprehensive warranty from the date of shipment
- Pricing Note: The market price for legacy Speedtronic boards varies based on global component availability. The listed price is a reference point. Please contact our international procurement team for a firm commercial quote.
Cross-Border Logistics and Import Regulations
Exporting specialized turbine control components requires compliance with strict international trade regulations. We utilize premium express carriers—primarily DHL and FedEx—to ensure rapid transport to power generation facilities worldwide, including North America, Europe, Australia, and the Middle East.
This specific board falls under HS Code 8537.10.91 for electronic control assemblies. When shipping to certain jurisdictions, customs clearance agents require an explicit declaration that the equipment is for commercial power generation use and does not have dual-use military applications. Our trade compliance team prepares all necessary export declarations, certificates of origin, and detailed commercial invoices. This approach keeps the package moving through customs checkpoints without unexpected holds or additional administrative delays at the destination port.
GE Mark VI TVBA Frequently Asked Questions
- Can the IS200TVBAH2ABB be hot-swapped while the turbine is running?Honestly, don’t attempt it. While some Mark VI boards allow live replacement, disconnecting a vibration termination board will interrupt critical protection loops, likely causing the VVIB module to flag a fault or initiate an immediate turbine trip.
- What is the difference between the H1, H2, and H3 versions of this board?The H2 revision features specific filter circuit tweaks and fuse layout changes compared to the H1. In our field experience, the H2 can usually replace an H1, but you must verify your exact firmware and VVIB software configuration in Toolbox ST before mounting it.
