Schneider Electric BMEXBP0400 Ethernet Backplane 4 Slot

Schneider Electric BMEXBP0400 Ethernet Backplane is a four-slot backplane for Modicon X80 racks that provides Ethernet and X-bus connectivity for I/O modules and is the same backplane used by Modicon M340, M580, and X80 modules. It features a stable in-rack mounting design and hot-swappable support for most I/O modules, supporting Schneider Electric's Easy Quantum modernization strategy. The backplane centers on a CPS power-supply slot and four I/O slots, with extension connectors to accommodate X-bus rack expansion, and includes Ethernet and X-bus connectors to accept both X-bus and Ethernet modules. The mechanical design includes mounting points for shielding connection bars, a protective ground screw, and mounting holes sized for common fasteners to secure the assembly in a rack. This backplane enables mixed Ethernet/X-bus I/O configurations in a compact footprint, simplifying upgrades from older Modicon hardware while preserving module compatibility in standard X80 chassis.
