Genuine GE IS215GFOIH1A / IS215GFOIH1AB / IS200GFOIH1A Excitation Controls | Mark VIe Series — Verified Source
Konmask.com supplies genuine General Electric excitation control boards for gas turbine and steam turbine generator systems operating on the GE Mark VIe distributed control platform. The IS215GFOIH1A, IS215GFOIH1AB, and IS200GFOIH1A are functionally interrelated field excitation output interface boards responsible for regulating generator field current, protecting excitation circuits, and interfacing with the Mark VIe I/O network. Procurement engineers sourcing these boards require verified provenance, functional test records, and reliable lead times — all of which Konmask provides as standard.

Our 4-Step Quality Verification Process
Every board shipped by Konmask passes through a documented four-stage inspection protocol before dispatch:
- Step 1 — Visual Inspection: Board surface, connectors, solder joints, and component markings are examined under magnification. Any signs of burn damage, corrosion, or counterfeit labeling result in immediate rejection.
- Step 2 — Firmware & Revision Verification: Part number, revision suffix, and GE date codes are cross-referenced against GE’s published hardware revision history to confirm authenticity and compatibility.
- Step 3 — Functional Bench Test: The board is powered in a controlled test environment. I/O signal paths, communication handshake with the IONet controller, and excitation output channels are verified against GE factory test parameters.
- Step 4 — Documentation Package: A test report, photographic record, and traceability certificate are issued with each unit. Customers receive full documentation at the time of shipment.
Key Features & Benefits

Authenticity & Trust FAQ
Q: How do I know the board is genuine GE?
A: Every unit is inspected against GE part number markings, date codes, and hardware revision identifiers. We provide a photographic inspection report with each shipment. If you have concerns, we can arrange a video inspection call before dispatch.
Q: What is the difference between IS215GFOIH1A and IS215GFOIH1AB?
A: The “B” suffix denotes Revision B — a GE-issued hardware update to the original IS215GFOIH1A. Both are functionally compatible in most Mark VIe applications. Consult your GE system documentation or contact us to confirm which revision is specified for your system.
Q: Can IS200GFOIH1A replace IS215GFOIH1A?
A: The IS200GFOIH1A is a predecessor variant. Cross-compatibility depends on your specific Mark VIe cabinet configuration and software version. Our engineers can advise based on your system details.
Q: What if the board fails within the warranty period?
A: We offer free replacement or full refund for any unit confirmed defective within 12 months of shipment, subject to our standard warranty terms. Return shipping costs are covered by Konmask for verified warranty claims.
Q: Do you offer exchange / core return programs?
A: Yes. We accept functional or repairable cores as part of an exchange program that can reduce your net cost. Contact us for current exchange pricing.
