Fig. 34: EL9400
Fig. 35: EL9410
The EL9400 and EL9410 power supply terminals are used to refresh the E­bus.
Data is exchanged between the coupler and the EtherCAT Terminal over the E­bus. Each terminal draws a
certain amount of current from the E­bus (see “current consumption E­bus” in the technical data). This
current is fed into the E­bus by the relevant coupler’s power supply unit. In configurations with a large
number of terminals it is possible to use the EL9400/EL9410 in order to supply an extra 2 A to the E­bus. As
opposed to the EL9400, the EL9410 has a diagnostic function which is displayed by LED and on the process
image. At the same time the EL9400 can be positioned for establishing a further potential group or for
supplying the terminals following on the right (via power contacts).
