EL3112-0011 – Introduction
Fig.18: EL3112-0011EtherCAT Terminal, 2-channel analog input, current, ±20 mA, 16-bit, differential
The EL3112-0011 analog input terminal processes signals in the range -20 … +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 EL3112-0011 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.
