EL3174 | EtherCAT Terminal, 4-channel analog input, multi-function, В±10В V, В±20В mA, 16В bitPreferred type

The EL3174 analog input terminal has four individually parameterizable inputs. Signals in the range from -10/0 to +10В V or -20/0/+4 to +20В mA can be processed via 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 inputs operate differentially, the current inputs are single-ended. All inputs are digitized with a resolution of 16В bits and transmitted, electrically isolated, to the higher-level automation device. With a technical measuring range of В±107% of the nominal range, the terminal also supports commissioning with sensor values in the limit range and diagnostics according to NAMURВ NE43.
