EL3014 - Introduction
Analog Input Terminals; 4 channel, 12 bits, 0 ... 20 mA, differential inputs
The EL3014 analog input terminal handles signals in the range from 0 to 20 mA. The current is digitized to a resolution of 12 bits, and is transmitted, in an electrically isolated form, to the higher-level automation device. The input channels of the EtherCAT Terminal are differential inputs and have a common reference ground, which is connected to the 0 V power contact.
Overcurrent is displayed not only in the process image, but also by an error LED for each channel.
