The GE IS200CABPG1B is a Control Assembly Backplane (CABP) Board manufactured by General Electric (GE).
While it belongs to the broad Mark VI Speedtronic series, it is specifically used as the backbone of a control assembly within a GE Innovation Series Drive Control System, which complements the main turbine control system.
⚙️ Key Details and Function
The IS200CABPG1B board is critical for the drive control assembly’s operation, providing the structure and connectivity for specialized electronic modules.
- Function: It is a multi-layer Printed Wiring Board (PWB) that serves as the main communication and power distribution backplane for the control modules in a drive system rack.
- Module Slots: It contains the physical slots (connectors) where specialized control boards plug in. Typically, it features 9 backplane connectors for control and interface modules.
- Common Modules: Boards that plug into this backplane include the IS200DSPX (Digital Signal Processor Control), IS200BAIA (Bridge Amplifier Interface), IS200BIC (Bridge Interface Card), and others.
- External Interfaces: The board provides numerous connectors (around 15) on its front face for external signal interfaces, including:
- User control Input/Output (I/O).
- ISBus ports for communication.
- Front panel keypad and meters.
- Diagnostic and configuration tool connections.
- Power Supply: It receives and distributes control power, often from an IS200HFPA High-Frequency AC/Fan Power Supply Board, which plugs directly into the backplane.
- Mounting: The CABP board is mounted into a dedicated Innovation Series board rack chassis.
The design of the IS200CABPG1B is engineered with different connector sizes and keys to ensure that boards and external connections can only be plugged into their correct respective locations, minimizing the chance of improper installation or damage.
