EL3064, EL3068, EL3164 | 4-, 8-channel analog input terminals 0…10 V, single-ended, 12/16 bits
The EL3064, EL3068 and EL3164 analog input terminals process signals in the range between 0 and 10 V. The voltage is digitised with a resolution of 12 bits (EL3064, EL3068) or 16 bits (EL3164) and is transmitted (electrically isolated) to the higher-level automation device. The EL3064/EL3164 EtherCAT Terminals feature 2-wire conductors for the four single-ended inputs with a common internal ground potential. The EL3068 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.
