The Beckhoff EK1100 EtherCAT Coupler is designed to connect EtherCAT Terminals (ELxxxx series) directly into 100BASE-TX networks with outstanding precision. Supporting up to 65,534 terminals, it ensures virtually unlimited expansion options. With a 24 V DC power supply, an E-bus current of 2000 mA, and 500 V electrical isolation, this model provides both power and safety for mission-critical automation.
Featuring dual RJ45 interfaces, data transfer rates of 100 Mbit/s, and a low internal delay of around 1 µs, the EK1100 Coupler is optimized for real-time communication. Its rugged IP20 housing, vibration resistance tested to EN 60068, and EMC compliance with EN 61000-6-2/6-4 guarantee stable operation even in harsh industrial settings. Certified with CE, UL, ATEX, IECEx, CCC, and DNV GL, it is widely trusted across industries including oil & gas, power, and manufacturing.
Applications of the EK1100 EtherCAT Coupler include production lines, robotics, and process automation where high-speed data exchange and modular I/O integration are essential. With compatibility for shielded Cat.5 cabling up to 100 m and reliable operation between -25°C to +60°C, it offers engineers both flexibility and assurance. This makes the Beckhoff EK1100 a preferred choice for modern automation systems using EtherCAT Terminals and EtherCAT Couplers.
