GE MARK VI IS200ICIAH1AAB BOARD

The part number you provided, GE IS200ICIAH1AAB, refers to a specific version of the Innovation I/O Board from the GE Mark VI Speedtronic Turbine Control System.

This part number is an extension of the base part number (IS200ICIAH1A) and indicates the specific revision and configuration of the board.

• IS200: Identifies the component as part of the GE Mark VI series.

• ICIA: Stands for Inverter Control Interface Adapter.

• H1A: Indicates the specific hardware configuration or version.

• AB: This is the revision code (Revision A, Revision B), which indicates minor modifications, bug fixes, or component changes from previous versions.

Function and Application

As an ICIA board, its core function is to:

1. Inverter/Excitation Interface: Serve as the primary interface and control board for components like the Static Starter (used to bring the turbine up to speed) or the Excitation System (used to control the generator’s output voltage).

2. I/O Processing: Condition, process, and transmit signals (both input from sensors and output to control devices) between the field devices and the main Mark VI processor.

3. Turbine Control: Play a critical role in the startup, shutdown, and steady-state control of the gas or steam turbine and its coupled generator.

Next Steps

This board is primarily found on the secondary market now, as the GE Mark VI system is an older generation.
