GE DS200VPBLG1A DS200VPBLG1ACC VME Backplane Board

Key Technical Specifications

This GE DS200VPBLG1A DS200VPBLG1ACC backplane accepts 6 VME modules in a single chassis. It routes power and signals between all connected cards. The unit measures 25 cm in length, 18 cm in width, and 2 cm in height. Its total weight equals 0.7 kg without any packaging materials.

The GE DS200VPBLG1A DS200VPBLG1ACC includes 6 DIN 41612 connectors for module insertion. Additionally, it features one 50-pin ribbon header for external system interface. A single 6-pin terminal block connects the main DC power input. The backplane contains 6 connectors, 3 bus bars, 2 voltage planes, and 12 decoupling capacitors.

GE DS200VPBLG1A DS200VPBLG1ACC distributes 120 µF total capacitance across all 6 slots. Each slot receives 20 µF local decoupling for stable operation. This arrangement filters high-frequency noise from the VME bus. Therefore, the board ensures clean power delivery to every plug-in module.

Design and Integration

Both the GE DS200VPBLG1A and DS200VPBLG1ACC versions share identical backplane routing. These boards use six-layer PCB construction with dedicated power and ground planes. Consequently, the GE DS200VPBLG1A DS200VPBLG1ACC operates reliably from -10°C to +60°C ambient temperature.

For installation, you need M4 screws for the six mounting holes. The backplane draws 10 mA typical current for LED indicators only. Each slot can deliver up to 10A continuous current to its module. We recommend using 10 AWG wire for the main power input connection.

Practical Application

This VME backplane serves as the mechanical and electrical backbone for a VME64 control rack. It hosts processor, I/O, and communication boards in one chassis. The GE DS200VPBLG1A DS200VPBLG1ACC distributes communication signals across a VME parallel bus. Therefore, it simplifies system integration for GE turbine control upgrades.
