4. Product Introduction (Anti-Template)
The IS200VTURH2BAC is a VTUR-series board used in GE Mark VI turbine control systems. It serves as a key interface for shaft speed signals and vibration transducers, and participates in primary turbine protection functions.
Working with the associated TTUR terminal board, the VTUR brings speed signals into the controllers where they are processed (often median-selected in redundant configurations). It supports overspeed protection logic and can contribute to trip signaling through the protection chain. In gas turbine applications it may also interface with flame detection related signals. The board mounts in the Mark VI VME rack and communicates with the control processors to support both monitoring and protective actions, including aspects of automatic synchronization in certain configurations.

5. QC, Procurement & Logistics SOP
- Inbound Verification – Confirm full part number (IS200VTURH2BAC), revision markings, connector condition, and faceplate/LED integrity. Photograph all labels.
- Live Rig Testing – Install in a compatible Mark VI VME rack, apply power, and verify board recognition plus basic speed/vibration signal path functionality where possible.
- QA & Packaging – After inspection, protect all connectors, clean the board, and pack in anti-static protective packaging with desiccant.
- Global Logistics & Export Compliance – Classify under the correct HS code for industrial control circuit boards. Packaging must protect against electrostatic discharge and mechanical shock; export documentation is prepared to minimize customs delays.
6. Technical Pitfalls & Integration Warnings
TTUR Terminal Board Matching – The VTUR must be correctly paired with the compatible TTUR terminal board. Mismatched or incorrectly wired terminal boards will cause speed or protection faults.
Speed Signal Wiring – Passive magnetic speed sensors require correct shielding and grounding. Noise or open circuits can trigger false overspeed or loss-of-speed events.
TMR Voting – In redundant systems the VTUR outputs participate in 2-out-of-3 voting for trip solenoids. Replacing a board requires understanding the voting status to avoid unexpected trips.
Configuration & Application Code – Protection thresholds and auto-synchronization enablement are controlled by the Mark VI application. Ensure the replacement board is recognized and configured correctly in the toolbox/software.
7. Frequently Asked Questions (FAQ)
What is the realistic global lead time for a verified IS200VTURH2BAC?
As a Mark VI board, availability depends on surplus stock. Typical lead time after verification is 5–15 business days plus standard air freight.
What is the function of the IS200VTURH2BAC?
It is the VTUR Vibration Transducer Interface / Turbine Protection board that handles shaft speed signals, vibration interfacing, and supports overspeed protection in Mark VI systems.
What system is it used with?
GE Mark VI Speedtronic turbine control systems.
What terminal board does it work with?
Primarily the TTUR terminal board and related protection terminal boards.
Does it participate in overspeed protection?
Yes. It brings speed signals into the controllers and supports the primary overspeed protection path.
Is it still in production?
Mark VI boards are mature/legacy. The IS200VTURH2BAC is primarily available through surplus and specialized repair channels.
What should be confirmed before ordering a replacement?
Exact part number including the full revision suffix (H2BAC), compatibility with the existing TTUR terminal board, and whether the system is Simplex or TMR.
