EL9400, EL9410 - Introduction and Technical Data
Power supply terminals
The EL9400 and EL9410 power supply terminals are 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 many terminals, it is possible to use the EL9400/EL9410 in order to supply an extra 2 A to the E-bus. 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/EL9410 can establish another potential group by an external 24 V feed-in via the power contacts on the right side.

Process data (only EL9410)
The EL 9410 has a bit width of 2 bits (diagnosis bits for the power contacts voltage [Up] and for the E-Bus voltage [Us], 'Undervoltage') and is displayed in the TwinCAT tree as follows:
If the Up or Us voltage is below 17 V, the corresponding diagnosis bit 'Undervoltage' has TRUE (1) status.
