EL3112 BECKHOFF EtherCAT Terminal, 2-channel analog input, current, 0…20 mA, 16 bit, differential

The EL3112 analog input terminal processes signals in the range between 0 and 20 mA. The current is digitized to a resolution of 16 bits and is transmitted, electrically isolated, to the higher-level automation device. The input channels of the EtherCAT Terminal have 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 EtherCAT Terminal indicates its signal state by means of light emitting diodes. The error LEDs indicate an overload condition.
