The EL3702 analog input terminal handles signals in the range between -10 and +10 V. The voltage is digitized to a resolution of 16 bits, and is transmitted, electrically isolated, to the controller.
TwinCAT 3.1 offers an option to manage TwinCAT software licenses via the EtherCAT Terminal EL6070. The EL6070 embodies the hardware license key in the modular EtherCAT I/O system. Data transfer takes place via EtherCAT.
Note that the EL6070 and EL6070-0033 are two different devices in terms of EtherCAT and are therefore not interchangeable in the EtherCAT I/O configuration.
