EK1914 | EtherCAT Coupler with integrated digital standard and safety I/Os

The EK1914 EtherCAT Coupler combines the functionalities of the EK1100 EtherCAT Coupler with standard and safe digital I/Os. This results in a compact design that is especially suitable for applications with a low number of I/Os. Like the EK1100, the EK1914 can be extended by all EL/ES terminals.

The EK1914 has four digital inputs and four digital outputs as well as two fail-safe inputs and two fail-safe outputs. The EK1914 meets the requirements of DIN EN ISO 13849-1:2008 (Cat 4, PL e).
