EL3174-0032 | 4-channel analog input terminal, -3…+3 V, -20/0/+4…+20 mA, electrically isolated, 16 bit
Description
The EL3174-0032 analog input terminal has four individually parameterisable inputs. Signals in the range from -3…+3 V or from -20/0/+4…+20 mA can be processed by each channel. Each channel should be set via the controller to U or I mode via CoE. The input voltage or current is digitised with a resolution of 16 bit, 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 an evaluation according to NAMUR NE43. The four differential inputs are electrically isolated against each other and against the fieldbus (2500 V DC).
