The GE IS200ICBDH1ABA is an Innovation Control Base Board (ICBD) manufactured by General Electric for their industrial control systems, primarily the Speedtronic Mark VI series for turbine control and the EX2100e excitation control system.
It functions as a primary control card that contains essential logic and interface circuitry for the main controller.
⚙️ Key Function and Application
The IS200ICBDH1ABA board serves as an efficient and vital component within the control cabinet, providing a great deal of I/O functionality within a relatively compact printed circuit board assembly (PCBA).
-
System Core: In the EX2100e Excitation Control System, the ICBD acts as a Control Base Card, which is fundamental to enhancing the functionality and performance of the system by controlling and regulating the generator excitation processes.
-
Contactor Control & Fault Monitoring: While the primary processing may reside on an external CPU board, the ICBD often manages critical functions such as:
-
Implementing hardware logic for bridge shutdown on a fault.
-
Providing control signals for MA and MB contactors (main power contactors).
-
Monitoring system and panel fault strings (interlock contacts).
-
-
Interfaces: The board is equipped with multiple communication and connection ports to integrate into the overall system:
-
Ethernet Jacks: Typically includes four jacks (e.g., J12A, J12B, J11A, J11B).
-
Serial Ports: Often includes an RS-232 female 9-pin port for diagnostics or configuration.
-
Conduction Sensors: Features two conduction sensors for monitoring temperature within the system.
-
Backplane Connectors: Connects to the system backplane to communicate with other I/O and processor boards.
-
The board revision is denoted by the suffix “ABA” on the base part number IS200ICBDH1A. The board is also built with a conformal coating for protection against moisture and contaminants in harsh industrial environments.
