Overview

The EL3172 analog input terminal supplements the EL3174, thus 2-channel and 4-channel universal input terminals are now available in the EL31xx family. The EL3172 has two single parameterizable inputs. Signals in the range ±10 V or ±25 mA can be processed by each channel, therefore of course also unipolar 0…10 V or 0/4…20 mA. Each channel should be set by the controller to U or I mode via CoE. The input voltage or cu...
