EL3058 - Introduction
Analog Input Terminal; 8 channels, 12 bits, 4 ... 20 mA, single-ended inputs
The EL3058 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 electronics is independent of the supply voltage of the power contacts. The power contacts are connected through; the reference ground of the inputs is the 0 V power contact.
The error LEDs signal overload and wire break.
