EL3044, EL3048, EL3144 | 4-, 8-channel analog input terminals 0…20 mA, single-ended, 12/16 bits
The EL3044, EL3048 and EL3144 analog input terminals process signals in the range between 0 and 20 mA. The current is digitised to a resolution of 12 bits (EL3044, EL3048) or 16 bits (EL3144) and is transmitted (electrically isolated) to the higher-level automation device. The EL3044/EL3144 EtherCAT Terminals feature 2-wire conductors for the four single-ended inputs with a common internal ground potential. The EL3048 version combines eight channels in one housing. The power contacts are connected through. The 0 V power contact is used as reference ground connection for the inputs. The signal state of the EtherCAT Terminals is indicated by light emitting diodes.
