EL3112 – Introduction
Fig.15: EL3112EtherCAT Terminal, 2-channel analog input, current, 0 … 20 mA, 16-bit, differential
The EL3112 analog input terminal processes signals in the range 0 … 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 Terminal are differential inputs and possess a common, internal ground potential. The EL3112 combines two channels in one housing. Overload condition is detected and the terminal status is relayed to the controller via the E-bus. The error-LEDs indicate an overload condition.
