EL9400, EL9410 - Introduction and Technical Data
Power supply terminals
Fig.39: EL9400, EL9410The EL9400 and EL9410 power supply terminals are used to refresh the E-bus via which the data exchange between EtherCAT Couplers and Terminals takes place. Each EtherCAT Terminal requires a certain current from the E-bus (see technical data: "Current consumption via E-bus"). This current is fed into the E-bus by the power supply unit of the respective EtherCAT Coupler. For configurations with a large number of EtherCAT Terminals, the EL9400/EL9410 can be used to increase the power supply to the E-bus by 2 A.
Unlike the EL9400, the EL9410 has diagnostics displayed by LED and in the process image. At the same time, the EL9400/EL9410 can establish a further potential group on the right-hand side by means of an external 24 V supply via the power contacts.

Process data (EL9410 only)
The EL9410 has a bit width of 2 bits (diagnostic bits for voltage Us [supply voltage for E-bus] and Up [voltage at the power contacts], "undervoltage") in the process image and is represented in the TwinCAT tree as follows:
Fig.41: EL9410 in the TwinCAT treeIf the Up or Us voltage drops below 17 V, the corresponding "Undervoltage" diagnostic bit is set to TRUE (1).
