Compatible Replacement & Equivalent Models
When the IS210TREAH1A is unavailable or discontinued, the following models may serve as functional equivalents or drop-in replacements depending on your system revision. Always verify firmware and rack compatibility before substitution:
- IS210TREAH1B – Revised hardware version; functionally equivalent in most Mark VI configurations
- IS210TREAH1C – Later revision with minor PCB updates; backward compatible
- IS200TREAH1A – Mark VIe compatible variant; verify I/O card pairing before use
- IS210TREAS1A – Simplex configuration terminal board; suitable for non-redundant systems
- IS210TREAH2A – Extended I/O channel variant; check channel count requirements
Note: Konmask.com engineers can assist with cross-reference verification. Contact us before ordering a substitute part.
Why Choose the Original Model
- Exact OEM Fit: IS210TREAH1A is the factory-specified termination board for Mark VI TREA-series I/O cards — no firmware or wiring adaptation required
- Proven Reliability: Validated in gas turbine, steam turbine, and combined-cycle plant environments worldwide

- Warranty & Traceability: Konmask supplies tested units with full inspection records and optional warranty coverage
- Long Service Life: Robust PCB construction rated for industrial temperature and vibration environments
Typical Applications
- Gas turbine control panels (GE Frame 5, 6, 7, 9 series)
- Steam turbine protection and governing systems
- Combined-cycle power plant (CCPP) automation
- Compressor station control using Mark VI architecture
- Retrofit and upgrade projects migrating from Mark V to Mark VI
- Spare parts inventory for power generation O&M teams
System Compatibility
- Primary System: GE Mark VI Speedtronic Turbine Control
- Compatible I/O Cards: TREG, TREA, TREAH series processor cards
- Controller Compatibility: Mark VI simplex and TMR (Triple Modular Redundant) configurations
- Not Compatible With: Mark V (IS200 series), Mark VIe without adapter — verify before ordering
- Software: Works with GE ToolboxST configuration environment
Selection Guide
Use the following criteria to confirm IS210TREAH1A is the correct part for your application:
- Step 1 – Identify your Mark VI revision: Check the system nameplate or ToolboxST project file for the I/O card model (TREG/TREA/TREAH)
- Step 2 – Count I/O channels: Confirm the terminal board channel count matches your field wiring requirements
- Step 3 – Check redundancy mode: TMR systems require matched terminal boards across all three controllers
- Step 4 – Verify signal types: Confirm analog/digital/RTD/TC signal mix matches IS210TREAH1A pinout
- Step 5 – Confirm hardware revision: H1A suffix indicates first hardware revision — check GE BOM for acceptable alternates

Replacement & Compatibility FAQ
Q: Can IS210TREAH1B replace IS210TREAH1A directly?
A: In most cases yes — the H1B is a hardware revision of the same board. However, always verify with your GE system documentation or contact Konmask for confirmation.
Q: Is IS210TREAH1A compatible with Mark VIe systems?
A: Mark VIe uses a different I/O architecture. The IS200 series terminal boards are typically required. Contact us to verify your specific configuration.
Q: Do you supply tested or new units?
A: We supply both. New (surplus) and fully tested refurbished units are available. Condition is clearly stated on each order confirmation.
Q: What is the lead time for IS210TREAH1A?
A: In-stock units ship within 3–5 business days. If sourcing is required, typical lead time is 7–15 business days.
Q: Can you help identify the correct replacement if my part number is different?
A: Yes. Send us your full part number, system model, and application details. Our engineers will provide a verified cross-reference within 24 hours.
