EL3044 - Introduction
Analog Input Terminal; 4 channels, 12 bits, 0 ... 20 mA, single-ended inputs
The EL3044 analog input terminal processes signals in the range from 0 to 20 mA. The current is digitized to a resolution of 12 bits and transported, electrically isolated, to the higher-level automation device.
The power contacts are connected through. The EtherCAT Terminals indicate overload via error LEDs.
In the EL3044 EtherCAT Terminal the four single-ended inputs are configured as 2-wire versions and have a common internal ground potential, which is not connected to the power contacts.
