Product Description:
The CU8803-0000-1900 is an EtherCAT junction module produced by Beckhoff within the CU EtherCAT Junctions series. Installed on a 35 mm EN 50022 DIN rail, it branches CP-Link 4, DVI, USB and Ethernet signals so multiple control panels can be connected to a single Industrial PC over one network segment. By combining data, video and peripheral channels inside a single metal enclosure, the unit simplifies cabinet wiring and supports decentralized machine-mounted operator stations in industrial automation lines.
The device is powered from a nominal 24 V DC source that is brought in through a pluggable terminal rated for 8 A. When a panel is attached, the internal distribution path can deliver up to 4.7 A to that load, allowing touchscreens and USB peripherals to receive steady auxiliary power. Environmental ingress protection is classified as IP20, indicating finger-safe openings that are intended only for clean, enclosed control cabinets. Data exchange over the USB uplink is specified at 100 Mbit/s, matching the bandwidth of many embedded HMI devices. Standard connectors include a DVI-D socket for video, an RJ45 port for CP-Link 4, and an upstream USB 2.0 Type B interface; each interface is galvanically isolated from the supply rail so ground loops are avoided.
A CP-Link 4 trunk is wired with Cat.6A cabling and may extend up to 100 m between junctions without repeaters, giving system designers flexibility in large production cells. The housing measures 70 × 100 × 80 mm, preserving cabinet depth while leaving room for adjacent I/O terminals, and the unit weighs only 745 g, reducing load on lightweight mounting plates. DVI and USB patch leads are limited to 1 m inside the enclosure to maintain signal integrity, while the metal shell shields sensitive video lines from nearby power conductors.
