![EL3072 | EtherCAT Terminal, 2-channel analog input, multi-function, ±10 V, ±20 mA, 12 bit](https://multimedia.beckhoff.com/media/el3072__web_preview.png)
The EL3072 and EL3074 analog input terminals are the 10 V/20 mA universal inputs of the 12-bit class. The EL3072 has two single parameterizable inputs. Signals either in the range -10/0…+10 V or in the range -20/0/+4…+20 mA can be processed by each channel. Physically, the voltage and current signals should be connected to different terminal points. Each channel should then be set by the controller/TwinCAT to U or I mode via CoE. The voltage and current inputs are single-ended, which means that one connection point of each channel is connected in the terminal to +24 V or GND. All inputs are digitized with a resolution of 12 bits and transmitted electrically isolated to the higher-level automation device. With a technical measuring range of ±107% of the nominal range, the terminal also supports commissioning with sensor values in the limit range and the evaluation according to NAMUR NE43.
