The EK1300 EtherCAT P coupler integrates the EtherCAT Terminals into the EtherCAT P network. The coupler converts the passing telegrams from Ethernet 100BASE-TX to E-bus signal representation. A station consists of a coupler and any number of EtherCAT Terminals that are automatically detected and individually displayed in the process image.The EK1300 has two P-coded M8 connections. The upper EtherCAT P interface is used to connect the coupler to the network, the lower P-coded M8 socket is used for optional continuation of the EtherCAT P topology. In addition, the EK1322 EtherCAT P junction or the EK1310 EtherCAT P extension can be used for extending or creating a line or star topology.Since EtherCAT P integrates the power supply and the communication on a single line, an additional power supply for the coupler via the terminal points is no longer required. Depending on the application, the system and sensor supply US or the peripheral voltage for actuators UP can be bridged to the power contacts.
