GE IS200TVBAH1ACC Vibration Terminal Board – Mark VI Turbine Control System
In a gas or steam turbine power plant, vibration monitoring is not optional — it is the last line of defense between normal operation and catastrophic mechanical failure. When the vibration terminal board fails or goes missing, the turbine control system loses its ability to receive, condition, and relay critical shaft and bearing vibration signals. The result: unplanned shutdowns, blind operation, and the very real risk of rotor damage that can cost millions in repairs and lost generation capacity. The GE IS200TVBAH1ACC is the precision interface that keeps this critical data flowing without interruption.
The IS200TVBAH1ACC is a Vibration Terminal Board designed specifically for GE’s Mark VI Turbine Control System — one of the most widely deployed turbine management platforms in the global power generation industry. Within the Mark VI I/O architecture, this board serves as the dedicated signal termination point for vibration transducers (proximitors, accelerometers, and velocity sensors), providing clean, conditioned inputs to the Mark VI controller. Its H1ACC revision designation reflects a mature, field-proven hardware iteration trusted by utilities, independent power producers, and industrial co-generation facilities worldwide.

Frequently Asked Questions
- Q: What is the difference between IS200TVBAH1ACC and other TVBA revisions?
- A: The H1ACC suffix denotes a specific hardware revision of the TVBA vibration terminal board. Different revision codes (e.g., H1A, H1B) may have minor PCB layout or component changes. Always match the exact revision code to your existing Mark VI rack to ensure compatibility.
- Q: Can IS200TVBAH1ACC be used with Mark VIe systems?
- A: The IS200TVBA series is primarily designed for the Mark VI platform. Mark VIe uses a different I/O architecture (IS420 series terminal boards). Cross-compatibility should be verified with GE documentation or our technical team before ordering.
- Q: Do you provide a warranty on refurbished boards?
- A: Yes. Refurbished and tested units carry a 12-month warranty against manufacturing defects. New surplus units carry the original OEM warranty terms where applicable.
- Q: How long does international shipping take?
- A: Standard express shipping (DHL/FedEx) typically takes 3–7 business days to most destinations. Expedited options are available for urgent plant maintenance requirements.
- Q: Can you supply multiple units for a fleet maintenance program?
- A: Yes. Konmask.com supports bulk and blanket purchase orders for utilities and EPCs managing multiple turbine units. Contact us to discuss volume pricing and stocking arrangements.
