The Beckhoff EK1521 is a 1-port EtherCAT junction designed to seamlessly integrate fiber optic technology into your automation system. This compact terminal allows for the conversion of EtherCAT signals from copper (100BASE-TX) to fiber optic (100BASE-FX), enabling communication over distances of up to 2 kilometers. By utilizing multimode fiber optic cable, the EK1521 provides excellent immunity to electromagnetic interference, making it ideal for use in electrically noisy industrial environments. It connects directly to other EtherCAT Terminals on a DIN rail, offering a space-saving and efficient solution for extending network segments or creating galvanically isolated sections within a control architecture.
