Product Description:
The CU8870-0000 is an interface module produced by Beckhoff within the CU EtherCAT Junctions series. Designed for control cabinets, it links USB peripherals and CompactFlash storage to automation controllers, allowing quick exchange of recipe data and event logs. In industrial installations, the unit functions as a small-footprint media junction that extends fieldbus diagnostics and file handling without requiring an additional power supply. It also supports removable media access in systems that need an external connection for archived process files and portable data exchange. Because it is powered directly over USB, the device eliminates separate wiring and can be installed alongside I/O terminals.
It is supplied directly from a USB host port, so the supply voltage requirement is 5 V DC. The permissible current draw is limited to 500 mA, ensuring the device does not overload standard industrial hubs. Mechanical mounting follows a 35 mm DIN rail profile and conforms to EN 50022, allowing quick snap-in assembly. The housing is rated IP20, which allows finger-safe access and indicates that installation inside closed enclosures is expected. The plastic housing keeps weight low, and any installation position is allowed, so the module can be rotated to suit space constraints inside the cabinet.
The CompactFlash interface accepts cards in the Type I/II format, and the module has one card slot, so no card selector is needed. Data leave the unit through a USB Type B connector, with stable signaling maintained when the cable length stays within 5 m. The electronics support both USB 1.1 and USB 2.0 protocols and permit data transfer rates of 12 Mbit/s and 480 Mbit/s. This arrangement supports file backups and other routine data transfers while keeping the connection layout simple. The USB link also lets the module share power and data through the same host connection.
