EL3022 - Introduction
Analog Input Terminal; 2 channels, 12 bits, 4 ... 20 mA, differential inputs
The EL3022 analog input terminal processes signals in the range from 4 to 20 mA. The current is digitized to a resolution of 12 bits and transported, electrically isolated, to the higher-level automation device. The input channels of the EtherCAT Terminal are differential inputs and have a common internal ground potential, which is not connected to the power contacts.
Overcurrent and wire break are displayed not only in the process image, but also by an error LED for each channel.
