The ELM9410 power supply terminal is used to increase the E-bus current. The exchange of data between EtherCAT Couplers and the connected EtherCAT Terminals takes place over the E-bus. Each EtherCAT Terminal requires a certain amount of current from the E-bus (see technical data at the respective terminal: “Current consumption E-bus“). This current is fed into the E-bus by the power supply unit of the respective EtherCAT Coupler. In configurations with a large number of EtherCAT Terminals, the ELM9410 can be used to increase the current supply to the E-bus by 2 A.
On account of three significant properties, the ELM9410 and the functionally identical EKM1101 EtherCAT Coupler are designed to meet the needs of high-precision analog measurement technology, e.g. with ELM3xxx terminals:
- To reduce interference in the connected terminal, both the E-bus supply US and the 24 V power contact supply UP are electrically isolated and filtered in the coupler. The power contact supply can carry a maximum load of 2 A.
- The extensive voltage and temperature monitoring provides assistance with commissioning and operation; results are displayed by LED and in the process image.
- The built-in three-axis position and vibration sensor allows a constant view of the mechanical situation in the control cabinet.
As a result, the ELM9410 can be used in special measuring situations instead of the conventional EL9410 supply. Mixed operation with EK1100/EL9410 is possible, however, not ensuring electrical isolation in this configuration.
