Turbine Control I/O Solution – GE IS200AEADH4A | Mark VI Series
Where This Product Is Used
The GE IS200AEADH4A Input Terminal Board is a critical I/O interface component deployed in GE Mark VI turbine control systems. It is widely used in the following industrial environments:
- Gas Turbine Power Plants – Provides analog and digital signal termination for turbine speed, temperature, and pressure sensors in combined-cycle and simple-cycle gas turbine units.
- Steam Turbine Control Systems – Interfaces field instrumentation with the Mark VI controller in steam-driven generation facilities.
- Compressor Stations – Used in pipeline and process compressor control panels where GE Mark VI platforms manage surge control and sequencing logic.
- Offshore Oil & Gas Platforms – Installed in hazardous-area control enclosures for turbine-driven pumps and generators.
- Industrial Cogeneration Facilities – Supports multi-unit turbine control architectures requiring reliable field signal conditioning and termination.

Application-Specific FAQ
Q: Is the IS200AEADH4A backward compatible with Mark V systems?
A: No. This board is designed specifically for the GE Mark VI platform. Mark V systems use a different I/O architecture and termination standard.
Q: Can this board be repaired rather than replaced?
A: Yes. Konmask.com offers board-level repair services for IS200 series components. Contact us for a repair quote and turnaround time.
Q: What is the difference between IS200AEADH4A and IS200AEAAH1A?
A: The H4A suffix denotes a specific hardware revision with modified termination layout. Always match the suffix to your existing system documentation to ensure pin-for-pin compatibility.
Q: Do you provide installation support?
A: Yes. Our engineering team can provide remote commissioning guidance and wiring verification for Mark VI I/O board replacements.
