EL3012 - Introduction
Analog Input Terminals; 1 and 2 channel, 12 bit, 0 ... 20 mA, differential inputs
The EL3011 and EL3012 analog input terminals process signals in the range between 0 and 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 EL3011/EL3012 EtherCAT Terminals are differential inputs and have a common internal ground potential, which is not connected to the power contacts.
Overcurrent is displayed not only in the process image, but also by an error LED for each channel.
The EL3011 is the single-channel version and is characterized by its fine granularity and electrical isolation. The EL3012 combines two channels in one housing
