Beckhoff EK1501-0018 EtherCAT coupler the Ethernet Fieldbus

EK1501 EtherCAT Coupler with ID switch, multi-mode fiber optic

The EK1501 EtherCAT Coupler with multi-mode fiber-optic connection is the link between the EtherCAT protocol at fieldbus level and the EtherCAT Terminals. The coupler converts the passing telegrams from Ethernet 100BASE-FX to E-bus signal representation. A station consists of a coupler and any number of EtherCAT Terminals that are automatically detected and individually displayed in the process image.

Special features:

connection technology 2 x multi-mode fiber-optic connection via SC duplex

connection lengths up to 2 km

3 ID switches for implementing variable topologies

number of EtherCAT Terminals in the overall system: up to 65,535
