The GE IS200BPVCG1BR1 is a Backplane Assembly (ASM) Interface Board specifically manufactured by General Electric (GE) for the Speedtronic Mark VI turbine control system.
The “R1” at the end of the part number typically denotes a specific Revision 1 of the board, which is an updated version of the IS200BPVCG1B. Functionally, it serves as the critical electronic backbone for the control system modules.
⚙️ Key Functionality and Specifications
The IS200BPVCG1BR1 board provides the primary physical and electrical connections for the main control cards within a Mark VI VME chassis.
- System Platform: GE Speedtronic Mark VI Turbine Control System.
- Role: Backplane Assembly Interface Board. It acts as the “motherboard” within the VME rack, supporting multiple control modules.
- Module Support: It is designed to fit into a rack system and accepts various Mark VI processor and I/O modules.
- Backplane Connectors: The rear portion of the board is populated with twenty-one (21) female backplane connectors. These connectors facilitate the parallel bus communication (VME bus) and power distribution between the control boards that plug into them.
- I/O Interface: The front portion of the board, which is intended to be left exposed outside the rack, contains thirty-nine (39) Input/Output (I/O) connectors. These connectors are used to attach ribbon cables, which route signals to and from the external field wiring terminal boards (TBCI, TBCA, etc.) that connect directly to the turbine’s sensors and actuators.
The board is crucial for reliable operation as it ensures stable power and high-speed data communication across the entire control module system.
