Schneider Electric 140XBE10000 Quantum Expander Module

Schneider Electric 140XBE10000 Modicon Quantum backplane expander is a dedicated expansion module that adds a second backplane to a Modicon Quantum PLC system, enabling I/O on an adjacent secondary backplane. Specifically designed for the Quantum platform, it expands I/O capability within either a local or Remote I/O (RIO) drop and occupies a single rack slot in the chassis, featuring a single Sub-D 37-pin connector for backplane communication. Linking backplanes is accomplished with Schneider’s backplane extension cables (for example, 140XCA7170 family), typically connecting one expander to the next to create a chain of backplanes. In practice, this module is documented as a rack expansion device used to provide an additional, separate backplane where Quantum I/O modules can reside, thereby scaling the overall I/O capacity of the system. The 140XBE10000 is cataloged and datasheeted as a Modicon Quantum backplane expander, reflecting its role within Schneider Electric’s Modicon Quantum automation platform.
