The EK18xx coupler series combines the functionalities of the EK1100 EtherCAT coupler with standard digital I/Os in a single housing. This results in a compact design with dimensions of just 44x100x68 mm that is especially suitable for applications with a small number of I/Os. Like the standard EK1100 coupler, the EK18xx couplers can be extended by all EtherCAT terminals. The digital I/Os are implemented with a single-wire technique, wiring can be implemented without tools using direct plug-in with single-wire conductors or wire end sleeves.
The following I/O variants are available:
* EK1814: four digital inputs/four digital outputs.
* EK1818: eight digital inputs/four digital outputs.
* EK1828: four digital inputs/eight digital outputs.
* EK1828-0010: eight digital outputs.
Beckhoff is consistently continuing the path towards miniaturisation of designs and cost optimisation with the EK18xx EtherCAT Coupler series. Tailored to applications with a small number of I/O points and cramped space conditions, the EK18xx coupler offers the user a precisely dimensioned solution.
The EtherCAT terminal system is a modular I/O system consisting of electronic terminal blocks. EtherCAT’s technological features are supported to the optimum, since the EtherCAT protocol is retained right down to the individual terminal. Suitable EtherCAT terminals are available for all common digital and analogue signal types encountered in the world of automation. Lower-level bus systems are integrated via local master/slave terminals.
Why secure industrial communication depends on deployment as well
Fieldbus & Industrial Networking
The Industrial Security Harmonisation Group has released a joint industry perspective highlighting a critical truth in industrial cybersecurity: secure communication is not determined by protocols alone, but by how they are deployed and managed in real-world environments.
