Information About CU1128-0000
The CU1128-0000 is part of Beckhoff’s CU series of EtherCAT infrastructure components, designed to extend and organize EtherCAT networks. It provides eight RJ45 ports for coupling EtherCAT junctions, enabling star topology configurations in distributed automation systems. With a transfer rate of 100 Mbit/s and minimal delay of approximately 1 µs per port, it ensures efficient and stable real-time data exchange. Its 24 V DC power supply, compact form factor, and compliance with CE and UL standards make it a reliable and robust networking component for industrial environments.
Key Features:
-
Eight RJ45 Ports: Offers 8 EtherCAT-compatible connections for branching and extending networks in flexible topologies.
-
High-Speed Communication: Supports full-duplex 100 Mbit/s transmission, ensuring reliable and efficient data handling.
-
Low Latency Switching: Introduces only ~1 µs delay per port, preserving EtherCAT’s real-time performance.
-
Strong EMC Compliance: Conforms to EN 61000-6-2 and EN 61000-6-4 standards for industrial immunity and emission.
-
Wide Power Supply Range: Operates on 24 V DC (18–30 V DC) with low current consumption of ~185 mA.
-
Industrial Certifications: Approved with CE and UL markings, guaranteeing compliance with global standards.
-
Robust Compact Housing: Slim 122 × 100 × 38 mm enclosure with IP20 rating ensures easy installation in cabinets.
-
Flexible Installation: Variable mounting positions allow adaptation to different control cabinet layouts.
The CU1128-0000 delivers the reliability and precision required for flexible EtherCAT network distribution and star topology configurations in automation systems.
