Product Description:

The CX2500-0070 is a peripheral module manufactured by Beckhoff for the CX Embedded PC Systems series. Classified as a USB 3.0 expansion block, the unit mounts beside a CX2000 controller to supply additional high-speed device connections. Within an automation cabinet it provides the physical USB interface required for diagnostics, data logging, or connection of barcode scanners, wireless adapters, and other service equipment that operate alongside fieldbus and motion tasks.

On its front panel the module presents four receptacles built to the Type A specification, the standard connector shape adopted by industry for removable USB cables. Internally these receptacles are routed through a Multi-Pin host interface that mates directly with the controller backplane, so no external cabling is needed between CPU and expansion. Mechanical placement is fixed; the housing is intended for the Left side of the base unit and locking tabs stop axial movement when the rail vibrates. System designers can cascade up to 4 of these modules in a row; this maximum module count prevents the total USB bus load from exceeding supply and bandwidth limits. Wiring sequence is marked as Irrelevant, meaning the ports negotiate independently and do not rely on any prescribed order during device commissioning.

In larger control assemblies, the add-on preserves the electrical grounding concept and EMC profile defined by Beckhoff. Its role is identified as a USB 3.0 Module, so every downstream socket supports SuperSpeed signaling at 5 Gbps in accordance with the USB 3.0 protocol layer. The module belongs to the CX Embedded PC Systems family, ensuring firmware recognition without additional drivers. While each block supplies four ports, the chainable architecture lets an engineer scale peripheral count to match application needs without reallocating fieldbus terminals or PLC task cycles.
