EL3144 | 4-channel analog input terminal 0…20 mA, single-ended, 16 bit

The EL3144 analog input terminal processes signals in the range between 0 and 20 mA. The current is digitised to a resolution of 16 bits and is transmitted (electrically isolated) to the higher-level automation device. The EL3144 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.
