The EL9400 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 EL9400 in order to supply an extra 2 A to the E-bus.
