EL3068 – BECKHOFF

EL3068 | EtherCAT Terminal, 8-channel analog input, voltage, 0…10 V, 12 bit, single-ended
The EL3068 analog input terminal processes signals in the range between 0 and 10 V. The voltage is digitized with a resolution of 12 bits and is transmitted (electrically isolated) to the higher-level automation device. The EL3068 EtherCAT Terminal 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 Terminal is indicated by light emitting diodes.
