BMXXBC120K Extension Cable | Schneider Modicon M340 Rack Bus

Product Description

The Schneider Electric BMXXBC120K is a backplane extension cable developed for the Modicon M340 automation platform. It enables reliable transmission of local backplane bus signals between chained racks in modular PLC architectures.

This 12-meter cable connects rack bus extender modules to additional backplanes, allowing physical separation of PLC racks without compromising communication stability. Therefore, engineers can design more flexible cabinet layouts while maintaining deterministic system behavior.

Moreover, the BMXXBC120K is manufactured to Schneider Electric industrial standards, ensuring consistent signal integrity under vibration, electrical noise, and long-term operation. It supports scalable automation systems while simplifying expansion and future upgrades.

As an active accessory within the Modicon M340 and X80 ecosystem, this cable aligns with Schneider’s long-term platform strategy. In addition, it supports standardized spare parts management and reduced lifecycle risks.
