EL3124 – Introduction
Fig.30: EL3124EtherCAT Terminal, 4-channel analog input, current, 4 … 20 mA, 16-bit, differential
The EL3124 analog input terminal processes signals in the range 4 … 20 mA. The current is digitized to a resolution of 16 bits and transmitted, electrically isolated, to the higher-level automation device.
The input channels of the EtherCAT Terminals have differential inputs and possess a common, internal ground potential. The EL3124 combines four channels in a single housing. A wire break or an overload condition are detected, and the terminal status is relayed to the controller via the E-bus.
The EtherCAT Terminal indicates its signal state by means of LEDs. The error LEDs indicate an overload condition and a wire break.
