Product Description:
The EJ1100 EtherCAT Coupler allows for direct communication between an EtherCAT plug-in module and the EtherCAT protocol at the fieldbus level. In order to facilitate the integration of process image-detected and -mapped plug-in modules, the coupler converts Ethernet 100BASE-TX telegrams to E-bus signals.
The EJ1100 EtherCAT coupler features two RJ45 sockets that support connection lengths up to 100 meters, allowing flexible network expansion. The upper Ethernet interface connects the coupler to the main network, while the lower socket enables the addition of further EtherCAT devices within the same segment. Reliable power distribution and communication are ensured by the coupler, which supplies the connected plug-in modules with up to 2.2 A at 3.3 V. The 60 mA plus the sum of the E-bus currents divided by 7.2 is the current usage from the supply voltage. To protect the EtherCAT interface from electrical interference, 500 V of isolation is provided. The coupler meets the requirements of EN 60068-2-6 and EN 60068-2-27 for vibration and shock resistance, and it can withstand humidity levels of up to 95% without condensation. The coupler is approved by CE and UL, has an IP20 certification, and complies with EMC immunity and emission standards EN 61000-6-2 and EN 61000-6-4.
The EJ1100 EtherCAT Coupler is ideal for use in industrial automation applications due to its polycarbonate enclosure and its design for installation on a signal distribution board. In addition to functioning from -25°C to +60°C, the coupler has a storage range of -40°C to +85°C. A proper and safe installation is guaranteed by the mechanical coding and latching lug. Optimizing system diagnostics and configuration is a vital aspect that involves automatically detecting and displaying plug-in modules in the process image.
