Beckhoff's EK1100 EtherCAT Coupler is the standard EtherCAT bus coupler that sits between the EtherCAT master and Beckhoff EtherCAT Terminals, bridging the EtherCAT Device Protocol with Beckhoff EL/ES/EM I/O modules. It does not provide standalone I/O; instead, it links the EtherCAT master to compatible Beckhoff terminal blocks, enabling real-time control of sensors and actuators via the EL/EM/ES families. As a member of Beckhoff's EK1xxx coupler lineup, the EK1100 is designed for direct use on the EtherCAT master to form the core interface of a distributed I/O system.
