Compatible Replacement & Equivalent Models
The following models are commonly evaluated as functional equivalents or drop-in replacements for the IS200VTURH1BAC. Compatibility depends on firmware revision, rack configuration, and system software version. Always verify with your GE system documentation before substitution.
- IS200VTURH1AAC — Earlier revision; functionally equivalent in most Mark VI configurations
- IS200VTURH1CAC — Later revision with enhanced diagnostics; backward-compatible in most racks
- IS200VTURH2BAC — Dual-channel variant for TMR (Triple Modular Redundancy) architectures
- IS215VTURH1B — Mark VIe series equivalent; requires updated IONet configuration
- DS200VTBCH1AEB — Legacy Mark V turbine protection board; not a direct drop-in, requires adapter
Note: Konmask.com stocks multiple revisions. Contact us to confirm the exact revision available and compatibility with your system.

Selection Guide
Use the following criteria to determine whether IS200VTURH1BAC is the correct part for your application:
- Step 1 — Confirm Control System: Verify your turbine runs on GE Mark VI or Mark VIe. Check the controller nameplate or GE Toolbox project file.
- Step 2 — Identify Rack Type: Determine if your rack is Simplex or TMR. TMR systems may require the dual-channel VTURH2 variant.
- Step 3 — Check Firmware Revision: The BAC suffix indicates a specific hardware revision. Confirm your system’s minimum firmware requirement in the GE Mark VI Application Manual (GEH-6421).
- Step 4 — Evaluate Alternatives: If BAC revision is unavailable, AAC or CAC revisions are typically interchangeable — confirm with your GE service engineer.
- Step 5 — Contact Konmask: Share your system serial number or Toolbox project export and we will confirm compatibility before shipment.

Replacement & Compatibility FAQ
Q: Can IS200VTURH1AAC replace IS200VTURH1BAC?
A: In most Mark VI configurations, yes. The AAC is an earlier hardware revision with identical functional behavior. Confirm firmware compatibility with GE Toolbox before installation.
Q: Is IS200VTURH1BAC compatible with Mark VIe?
A: Yes, with appropriate IONet configuration. The Mark VIe uses the same card family but may require updated firmware. Consult your GE Toolbox project file.
Q: What is the difference between VTURH1 and VTURH2?
A: VTURH1 is a single-channel protection card for Simplex systems. VTURH2 is a dual-channel variant designed for TMR redundancy architectures.
Q: Do you offer tested/refurbished units?
A: Yes. All refurbished units are functionally tested and clearly labeled. Test reports are available upon request.
Q: What is the lead time?
A: In-stock units ship within 1–3 business days. Out-of-stock items typically have a 2–6 week lead time. Contact us for current availability.
Q: Can I return a part if it is not compatible?
