Description

The KL3002 analog input terminal handles signals in the range from -10 to +10 V. The voltage is digitised to a resolution of 12 bits and is transmitted, electrically isolated, to the higher-level automation device. The input channels of the Bus Terminal have differential inputs and possess a common, internal ground potential. The light emitting diodes give an indication of the data exchange with the Bus Coupler.
