Available. The Beckhoff EK1814 is an EtherCAT Coupler designed to integrate EtherCAT Terminals (ELxxxx) into 100BASE-TX EtherCAT networks. It features four digital inputs and four digital outputs, making it ideal for applications requiring a compact I/O solution. The coupler converts Ethernet 100BASE-TX telegrams into E-bus signals, facilitating seamless communication between the network and connected terminals. It supports up to 65,534 EtherCAT Terminals in the overall system, offering scalability for complex automation setups. The EK1814 is equipped with two RJ45 sockets: the upper interface connects to the network, while the lower socket allows for the optional connection of additional EtherCAT devices within the same segment. This design supports flexible network topologies, including line and star configurations. The coupler operates with a nominal voltage of 24 V DC (-15%/+20%) and provides a current supply of 1,000 mA for the E-bus. It can supply up to 5 V and 1 A for connected EtherCAT Terminals; for higher current requirements, power feed terminals like the EL9410 are recommended. The field supply is forwarded to individual I/O components via power contacts, supporting up to 10 A. The EK1814 is housed in a compact HD (High Density) enclosure with signal LEDs, measuring 44 mm x 100 mm x 67 mm, and is designed for mounting on a 35 mm DIN rail. It operates within a temperature range of -25°C to +60°C and complies with various standards, including EN 60068-2-6, EN 60068-2-27, EN 61000-6-2, and EN 61000-6-4, ensuring reliability in industrial environments.
