The IS200BICHH1A is a “Normal Assembly” PCB (IS200 series) designed for internal mounting within a control cabinet.3 Its function is to manage and condition the signals between the turbine controller and the drive’s local control system.

Parameter Detail
Functional Acronym BICH (Bridge Interface Control Board)
System Family GE Mark VI Speedtronic / Drive Control Series.
Primary Function Acts as a communication and control bridge between the main processor and drive systems, often providing signal isolation, conditioning, and diagnostics.
I/O and Connectivity Densely populated with components, including jumpers, fuses, relays, integrated circuits, and multiple vertical female plug connectors for interfacing with auxiliary modules or the backplane.
Signal Handling Handles a mix of signals, typically including current loop analog inputs ($\text{mA}$ signals) and discrete inputs ($\text{DI}$), which are filtered and prepared for the main controller.
Revision H1A specifies the exact hardware and firmware revision.

🛠️ Key Technical Features

  • Signal Conditioning: The board contains complex passive and active circuitry to filter noise and condition field signals, ensuring high signal integrity before they reach the main controller.4
  • Isolation and Protection: It provides electrical isolation between the control circuits and the field wiring to protect the sensitive electronics from voltage transients and ground potential differences. The inclusion of fuses offers basic circuit protection.5
  • Configuration: The presence of jumpers allows field configuration of certain I/O channels, such as selecting between voltage and current input ranges, tailoring the board to the specific field application.
  • Diagnostics: The board typically includes test points and LEDs for local diagnostics, aiding in troubleshooting.

⚠️ Important Considerations for Replacement

  • Revision Match is Crucial: The H1A suffix must be matched exactly when replacing the board. GE Mark VI systems are highly sensitive to revision differences, which can cause incompatible signal scaling, communication failures, or incorrect control logic execution.
  • Configuration: If the board includes jumpers, the replacement board must be configured with the exact same jumper settings as the unit being replaced to ensure correct operation.
