EtherCAT Coupler

The Beckhoff EtherCAT Terminals combine the compact form factor and signal variety of the well-known Beckhoff Bus Terminal series with the ultra-high performance of EtherCAT. The system comprises a selection of digital and analog I/O terminals as well as special sensor interfaces for position measurement, serial communication interfaces and fieldbus gateway terminals. The performance is outstanding: e.g. analog signals can be sampled and communicated with an update rate of 20 kHz - if the master permits such update cycles. The EtherCAT terminal are proven and tested in a variety of pilot applications since 2003.

EK1100 | EtherCAT Coupler
The EK1100 coupler connects EtherCAT with the EtherCAT Terminals (ELxxxx). One station consists of an EK1100 coupler, any number of EtherCAT Terminals and a bus end terminal. The coupler converts the passing telegrams from Ethernet 100BASE-TX to E-bus signal representation.

EK1101 | EtherCAT Coupler with ID switch
The EK1101 coupler connects EtherCAT with the EtherCAT Terminals (ELxxxx). A station consists of an EK1101 coupler, any number of EtherCAT Terminals, an EL9011 bus end cap or an EK1110 EtherCAT extension.

EK1501 | EtherCAT Coupler with ID switch, fibre optic
The EK1501 coupler connects EtherCAT with the EtherCAT Terminals (ELxxxx). A station consists of an EK1501 coupler, any number of EtherCAT Terminals, an EL9011 bus end cap or an EK1110 EtherCAT extension.

EK1521 | 1-port EtherCAT fibre optic junction
In conjunction with an EK1100 EtherCAT Coupler, the 1-port EtherCAT fibre optic junction enables conversion from 100BASE-TX to 100BASE-FX physics (glass fibre). Distances of up to 2 km can be bridged with the EK1521 and the EK1501 EtherCAT Coupler for multimode fibre optics.

EK1122 | 2-port EtherCAT junction
The 2-port EtherCAT junction enables configuration of EtherCAT star topologies. A modular EtherCAT star can be realised by using several EK1122 units in a station.

EK1110 | EtherCAT extension
Like the E-bus end terminal, the EK1110 EtherCAT extension is connected to the end of the EtherCAT Terminal block. The terminal offers the option of connecting an Ethernet cable with RJ 45 connector, thereby extending the EtherCAT strand electrically isolated by up to 100 m.

BK1120 | EtherCAT Coupler for standard Bus Terminals
The BK1120 Bus Coupler connects EtherCAT, the real-time Ethernet system, with the modular, extendable electronic terminal blocks. A unit consists of a Bus Coupler, any number (between 1 and 64) of terminals (255 with K-bus extension) and one end terminal.

BK1250 | “Compact” Coupler between E-bus and K-bus Terminals
The BK1250 is a “Bus Coupler in terminal housing” for mixed application of EtherCAT Terminals (ELxxxx) and standard Bus Terminals (KLxxxx) in a bus station.
