Information About CU1128-1005
The CU1128-1005 is a Beckhoff EtherCAT junction device that provides eight RJ45 ports for coupling EtherCAT segments in line, tree, or star topologies. It allows multiple EK1100 couplers or EtherCAT Box modules to be connected simultaneously and includes direct LED indicators for link and activity status. Operating at 100 Mbit/s, it ensures low-latency communication with delays of approximately 1 µs per port. The unit is powered by 24 VDC (18–30 VDC range) and consumes up to 185 mA, with improved efficiency from hardware version 08 onward. Its rugged industrial design includes vibration and shock resistance, EMC compliance to EN 61000-6-2/-6-4, and an IP20 protection class for installation in control cabinets. With support for distributed clocks and hot-connect functionality, the CU1128-1005 is an essential networking module for large and complex EtherCAT automation systems.
Key Features:
- Eight RJ45 EtherCAT Ports: Connects up to eight EtherCAT network segments while supporting line, tree, and star topologies.
- Hot-Connect Support: Allows EtherCAT branches to be added or removed during operation without shutting down the network.
- Real-Time Communication: Transfers data at 100 Mbit/s with approximately 1 µs delay per port for deterministic performance.
- Distributed Clocks: Maintains precise synchronization between connected EtherCAT devices for motion and automation control.
- Wide Power Input: Operates from a 24 VDC supply with an acceptable input range of 18–30 VDC.
- Industrial-Grade Construction: Designed to withstand vibration, shock, and electromagnetic interference in harsh environments.
- Compact DIN Rail Design: Mounts easily on standard 35 mm DIN rails while minimizing cabinet space requirements.
- Certified Reliability: Complies with CE, EAC, UKCA, and cULus standards for industrial installations.
The CU1128-1005 delivers the reliability and precision required for expanding EtherCAT networks, synchronizing distributed devices, and supporting high-performance industrial automation systems.
