GE IS200ICBDH1ABB printed circuit board

The GE IS200ICBDH1ABB is a Control Base Card (often referred to by the acronym ICBD) primarily used within the GE Mark VI Speedtronic Turbine Control System and the EX2100 Excitation System.

This board acts as a fundamental interface and communication hub within the control system rack.

⚙️ Core Function and Features

The IS200ICBDH1ABB is essential for enabling high-speed data exchange, modular diagnostics, and interfacing with other I/O boards:

• Control Base Card: It serves as a foundational interface board that connects to and coordinates multiple I/O and processor modules within the control cabinet.

• Connectivity Hub: It features a wide variety of connection points necessary for an industrial control system:

  • Ethernet Jacks (J12A, J12B, J11A, J11B): For network communication, often supporting redundancy.

  • RS-232 Port (9-pin): For serial communication with external devices.

  • 96-pin Female Ports: Multiple high-density ports for complex data and control signal transmission from other boards.

  • Stab-on Connectors (CHAS, CCOM): For dedicated power distribution and communication routing.

• Signal Processing: The board is designed for precise control and efficient data processing, enabling it to manage complex tasks required for reliable turbine and generator operation.

• Robust Design: Its specifications show a wide operating temperature range (from −30∘C to 65∘C) and it is often protected by a conformal coating to withstand harsh industrial environments.

The final ABB suffix indicates the specific hardware and artwork revision of the board, which is important for compatibility when used as a replacement part.
