EL3004 - Introduction
Analog Input Terminal; 4 channels, 12 bits, -10 V ... +10 V, single-ended inputs
The EL3004 analog input terminal processes signals in the range from -10 to +10 V. With a resolution of 12 bits, the voltage is digitized and transported, electrically isolated, to the higher-level automation device.
The power contacts are connected through.
In the EL3004 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.
