The GE IS200AEBIH1ADC is a highly specific Printed Circuit Board (PCB) from General Electric’s Mark VI Speedtronic Turbine Control System.
While specific documentation for the exact H1ADC revision is proprietary, the core function is defined by the acronym AEBI, which stands for Alternative Energy Bridge Interface.
⚙️ Product Profile: IS200AEBIH1ADC
The AEBI board is an essential communication and signal bridge used to integrate specialized or auxiliary systems into the main Mark VI control platform. It is a “Normal Assembly” board (IS200 series) designed to be mounted inside the control cabinet, not in a VME rack.
| Part Segment | Meaning | Detail |
| IS200 | Board Series | Component in the GE Mark VI Speedtronic System. |
| AEBI | Functional Acronym | Alternative Energy Bridge Interface. Acts as a communication gateway for specialized auxiliary control, particularly in wind turbine applications or complex drive interfaces. |
| H1 | Assembly Variant | Denotes the first hardware version using Surface-Mount Technology (SMT). |
| ADC | Revision/Coating | Specifies the exact functional and artwork revision level. The ‘C’ often indicates a Conformal Coating for environmental protection. This specificity is crucial for replacement. |
🛠️ Key Technical Features and Function
The AEBI board’s purpose is to ensure reliable, high-speed data exchange between the main turbine control processor and a distinct subsystem, often a high-speed drive or a specialized pitch control module in an Alternative Energy context.
- Communication Bridge: Its main role is to act as an interface, often translating or conditioning signals from an auxiliary system before they are sent over the proprietary ISBus to the main controller.
- Target Application: The board was developed by GE Energy and is primarily associated with wind turbine control systems, where the Mark VI platform was adapted to manage the unique demands of pitch and yaw control and grid interface.
- High Component Density: Like other IS200 series boards, the AEBI is densely populated with components (resistors, capacitors, and integrated circuits) to ensure precise signal regulation, filtering, and processing.
- Environmental Protection: The conformal coating (implied by the revision code) is vital for industrial environments, protecting the electronics from moisture, dust, and corrosive air.
⚠️ Important Considerations for Replacement
- Revision Match is Critical: The full part number, including the H1ADC suffix, is non-negotiable for replacement. GE Mark VI systems are highly sensitive to revision matching to ensure software compatibility and correct signal handling.
- ESD Precautions: Due to the dense concentration of sensitive integrated circuits, strict Electrostatic Discharge (ESD) handling procedures must be followed during installation or removal.
