BECKHOFF EL3121 analog input terminal module
The EL3121 analog input terminal processes signals in the range between 4 and 20 mA. The current is digitized to a resolution of 16 bits and is transmitted, electrically isolated, to the higher-level automation device. The input channels of the EtherCAT Terminal have differential inputs and possess a common, internal ground potential. The EL3121 is the single-channel version and is characterized by its fine granularity and electrical isolation.
