Connection
EL3014, EL3114 | 4-channel analog input terminals 0…20 mA, differential input, 12/16 bits
The EL3014 and EL3114 analog input terminals process signals in the range between 0 and 20 mA. The current is digitised to a resolution of 12 bits (EL3014) or 16 bits (EL3114) and is transmitted, electrically isolated, to the higher-level automation device. The input channels of the EtherCAT Terminals have differential inputs and possess a common, internal ground potential. Overload condition is detected, and the terminal status is relayed to the controller via the E-bus. The EtherCAT Terminals indicate their signal state by means of light emitting diodes.
