EL3602 | 2-channel analog input terminal ±10 V, ±5 V, ±2.5 V, ±1.25 V, differential input, 24 bit

The EL3602 analog input terminal handles signals in the ranges ±10 V, ±5 V, ±2.5 V and ±1.25 V. The voltage is digitised to a resolution of 24 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 signal state of the EtherCAT Terminal is indicated by light emitting diodes.
