EK1100 Beckhoff EtherCAT Coupler Connect EtherCAT Protocol to Terminal Modules
The Beckhoff EK1100 is a high-performance EtherCAT coupler that serves as the critical link between the EtherCAT protocol at fieldbus level and EtherCAT terminal modules. This essential coupling device converts Ethernet 100BASE-TX transmission messages into E-bus signals, enabling seamless communication between the EtherCAT network and connected terminal modules.
Designed for industrial automation applications, the EK1100 features two RJ45 Ethernet interfaces supporting connection lengths up to 100 meters, allowing flexible network topology configurations. The coupler supports up to 65,535 EtherCAT terminal modules in a single system, providing exceptional scalability for complex automation projects.
The EK1100 incorporates automatic terminal detection and displays all connected modules individually in the process image. With robust 24V DC power supply capabilities and comprehensive EMC immunity/emission compliance to EN 61000-6-2/EN 61000-6-4 standards, this coupler ensures reliable operation in demanding industrial environments.
