4-channel analog input, parameterisable, -10/0…+10 V, -20/0/+4…+20 mA, 16 bit
| Information | |
| About product | The EL3174 analog input terminal has four individually parameterisable inputs. Signals in the range from -10/0 to +10 V or -20/0/+4 to +20 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 digitised with a resolution of 16 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 diagnostics according to NAMUR NE43 |
