The EL3174-0002 analog input terminal has four individually parameterizable inputs. Signals in the range from -10/0 to +10 V or -20/0/+4 to +20 mA can be processed via each channel. Each channel should be set by the controller to U or I mode via CoE. The input voltage or current is digitized with a resolution of 16 bits, and is 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 diagnostics according to NAMUR NE43. The four differential inputs are electrically isolated against each other and against the fieldbus (2,500 V DC).
