This results in a compact solution with dimensions of just 44 mm x 100 mm x 68 mm (W x H x D) that is suitable for applications that require only a small number of I/Os. The coupler integrates an HD (High Density) terminal, which offers 16 I/O connection points in a compact format. Four channels are reserved for the supply voltage and the remaining, up to 12 are available for digital I/Os that previously would have required the purchase of a separate I/O terminal. The 12 available channels on the series can be configured in different I/O combinations to suit the respective application. They combines the functionalities of the company's EK1100 EtherCAT Coupler with standard digital EtherCAT I/Os in one compact housing. Like the existing coupler, the new couplers can be extended into a full industrial Ethernet I/O system using all EtherCAT Terminals. Available couplers include the EK1814, with four digital inputs/four digital outputs; the EK1818, with eight digital inputs/four digital outputs; the EK1828: four digital inputs/eight digital outputs and the EK1828-0010, with eight digital outputs.
