GE IS200GFOIH1BBA Auxiliary Board

الوصف

The GE IS200GFOIH1BBA is another specific revision of the Ground Fiber Optic Interface Board (GFOI).

It is not a general “Auxiliary Board,” but rather a specialized communication and safety interface module used in General Electric’s Mark VI Speedtronic Turbine Control System and related high-power applications like the EX2100 Excitation Control.

💡 Core Function

The IS200GFOIH1BBA’s function is identical to the other GFOI boards, emphasizing data integrity and electrical isolation in harsh industrial environments:

1. Fiber Optic Interface: It converts electrical control signals to light pulses for highly reliable transmission over fiber optic cables, and converts the light back to electrical data upon receipt.
2. EMI Immunity: This fiber optic medium is crucial because it makes the control signals completely immune to Electromagnetic Interference (EMI), noise, and high-voltage transients present in turbine and exciter cabinets.
3. Isolation: It provides essential electrical isolation between different sections of the control system that may operate at varying ground potentials or voltage levels, protecting sensitive electronics from damage.
4. Ground Fault Management: The “Ground” in the name indicates its role in accurately communicating ground-related fault signals or status information from the power section to the main controller for rapid protection.

The suffix G1BBA indicates a specific manufacturing revision, which ensures the core functionality remains stable across production updates.
