EL3011 - Introduction
Fig.12: EL3011EtherCAT Terminal, 1-channel analog input, current, 0 … 20 mA, 12-bit, differential
The EL3011 analog input terminal processes signals in the range 0 … 20 mA. The current is digitized to a resolution of 12 bits and transmitted, electrically isolated, to the higher-level automation device. The input channel of the EL3011 EtherCAT Terminal is a differential input and has an internal ground potential that is not connected to the power contacts.
Overcurrent is displayed not only in the process image, but also by an error-LED.
The EL3011 is the 1-channel version and is characterized by its fine granularity and electrical isolation.
