GE DS200VPBLG2A VME Backplane Board

Product Description

The DS200VPBLG2A is a VME Backplane Board manufactured by General Electric (GE) Industrial Systems for the LS2100 Series. It provides board-level connections and signal distribution between control boards installed in the system. The board features eight VME connectors, a 34-pin ribbon connector for external exciter signals, and a 12-pin power connector. It also uses ten power connection points to electrically connect the VPBL board to the P1 backplane.

Technical Specifications

VME Backplane and Board Connections

The DS200VPBLG2A provides the VME backplane connections for control boards in the LS2100 system. Its J2 section contains eight VME-type connectors. Six connectors use double-wide spacing, while the remaining two use single spacing.

These connectors provide the board-level connection points for the system configuration. The J2 section supports a DSPC board, up to three Gate Distribution Status Boards, one exciter board, and an I/O extender daughterboard.

Power Distribution

The board contains ten power connection points, also referred to as power bugs. These points electrically connect the VPBL board to the P1 backplane.

Furthermore, the JAA connector provides a 12-pin Mate-n-Lock power connection. Its documented signal nomenclature includes DCOMI, the isolated digital common ground, and ACOMI, the isolated analog common ground. These separate ground references support the corresponding digital and analog power connections.

External Exciter Interface

The DS200VPBLG2A uses a 34-pin ribbon connector designated EXJV to handle signals associated with the external exciter bridge. This connection provides the signal interface between the exciter circuitry and the backplane.

Therefore, the EXJV connector should be considered when checking the board configuration and external exciter signal connections during maintenance or replacement.

Diagnostics Interface

The diagnostics connector provides input and output connections to the processor in the J1 section. Its pin assignments include individual signal names, nomenclatures, and descriptions.

For detailed pin identification and signal mapping, the GEI-100227 VME Backplane Board VPBL User's Guide provides the relevant connector information.

Frequently Asked Questions
