3、 介绍文档： 4、 The EL9410 power supply terminal is used to refresh the E-bus. Data is exchanged between the coupler and the EtherCAT Terminal over the E-bus. Each terminal draws a certain amount of current from the E-bus (see “current consumption E-bus” in the technical data). This current is fed into the E-bus by the relevant coupler’s power supply unit. In configurations with a large number of terminals it is possible to use the EL9410 in order to supply an extra 2 A to the E-bus. The EL9410 has a diagnostic function which is displayed by LED and on the process image. 5、 EL9410电源终端用于刷新E总线。数据通过E总线在连接器和EtherCAT终端之间交换。每个终端从E-bus中吸取一定量的电流（见技术数据中的“电流消耗E-bus”）。该电
