Product Description:
The CU8810-0010 is a compact signal extender manufactured by Beckhoff and delivered within the CU EtherCAT Junctions series. Designed for installation on a DIN rail inside a control cabinet, it combines video and peripheral links so that industrial PCs can drive multiple operator panels over long distances. The unit routes DVI and USB streams through a single twisted-pair extender line, allowing decentralized HMI stations while the computing hardware remains inside a protected control cabinet. This arrangement is useful when displays and input devices must be placed near the machine while the host PC stays in the cabinet.
Video distribution is handled through a front panel equipped with a DVI-D interface. The unit provides 2 DVI input ports for independent video sources, and the signals are duplicated across 4 DVI output ports so identical images can reach several monitors. Inside the junction, a serializer supports a bandwidth of 1.65 Gbit/s, which matches the maximum data rate for single-link DVI. Signal integrity is maintained over shielded cabling, and the permissible reach is 50 m between the junction and the remote converter. The housing measures 146.5 × 100 × 38 mm and fastens to a 35 mm EN 50022 rail, which helps keep the device aligned with other DIN-mounted components in the cabinet.
Peripheral connections start with a single upstream USB Type-B socket that presents the controller interface. The junction fans the signal out to 4 USB extender ports on the field side, which lets input devices be grouped near the operator location instead of being wired directly back to the PC. High-speed traffic moves at up to 480 Mbit/s, allowing keyboards, touchscreens, and storage media to function without delay. Compliance with USB 2.0 ensures broad compatibility with industrial peripherals. All extended links share an RJ45-based connector, simplifying cable routing alongside EtherCAT lines. The node draws its logic and extender power from a 24 V DC power supply, so no additional voltage rails are required.
