IS200BPVCG1BR1 | GE Backplane Interface Board
The IS200BPVCG1BR1 is a backplane interface printed circuit board (PCB) developed by General Electric for the Speedtronic Mark VI Turbine Control System series. It installs into a standard VME rack assembly, serving as a primary signal distribution hub that interconnects internal processing boards with external input/output cabling across heavy-duty gas, steam, and wind turbine applications.
Architectural Layout and Interconnect Design
The PCB is structured into two functional sections to facilitate rack integration. The rear section houses 21 female backplane connectors surrounded by physical card-guide walls that support and lock inserted VME modules into position. The front section remains exposed outside the rack enclosure, accommodating 39 high-density ribbon cable connectors for direct field and module I/O connections.
Board Components and Signal Routing
To support power distribution, grounding, and signal conditioning across attached modules, the board features 14 heavy-duty stab-on terminal connectors and 6 resistor network arrays. The bottom side of the PCB is populated with 30 surface-mount components designated as inductors/filters L1 through L30 to mitigate electromagnetic interference (EMI) across signal paths.
Technical Specifications
| Parameter | Specification |
|---|---|
| Model | IS200BPVCG1BR1 |
| Brand | General Electric |
| Product Type | Backplane Interface Boards |
| System Line | Speedtronic Mark VI |
| Functional Acronym | BPVC |
| Form Factor | VME Rack Mountable (with faceplate) |
| Board Coating | Normal Conformal Coating |
| Revision Level | Revision 1B (Group 1) |
| Female Backplane Connectors | 21 connectors (internal rack interface) |
| Field I/O Connectors | 39 ribbon cable connectors (external interface) |
| Power / Ground Terminals | 14 stab-on connectors |
| Passive Signal Networks | 6 resistor network arrays |
| On-Board Filtering | 30 surface-mount components (L1 through L30) |
Installation and Handling Requirements
The IS200BPVCG1BR1 installs directly into the rear slot alignment of a compatible Mark VI VME rack. Because the board contains static-sensitive integrated circuits and passive arrays, personnel must wear grounded ESD wrist straps during handling and installation. Ensure all external ribbon cables are seated and locked onto the 39 header connectors before restoring system control power.
Frequently Asked Questions
Q: Is the IS200BPVCG1BR1 board mounted inside the VME rack or external to it? A: The board mounts directly inside the VME rack assembly via its integrated installation faceplate, positioning its female connectors internally while leaving its 39 ribbon cable connectors accessible externally.
Q: What is the function of the 14 stab-on connectors on this board? A: The 14 stab-on connectors provide dedicated connection points for high-current power distribution and system frame grounding across the backplane assembly.
Q: How can I verify the functional revision and coating type of this board? A: The part number IS200BPVCG1BR1 indicates normal PCB coating (denoted by the 'C') and functional revision 1B (denoted by 'R1' and 'B').
