EL3044 – BECKHOFF

EL3044 | EtherCAT Terminal, 4-channel analog input, current, 0…20 mA, 12 bit, single-ended
The EL3044 analog input terminal processes signals in the range between 0 and 20 mA. The current is digitized to a resolution of 12 bits and is transmitted (electrically isolated) to the higher-level automation device. The EL3044 EtherCAT Terminal features 2-wire conductors for the four single-ended inputs with a common internal ground potential. The power contacts are connected through. The signal state of the EtherCAT Terminal is indicated by light emitting diodes.
