Overview

The KL3021 analog input terminal handles signals in the range from 4 to 20 mA. The current is digitized to a resolution of 12 bits and is transmitted, in an electrically isolated form, to the higher-level automation device. The input channels of the Bus Terminal have differential inputs and possess a common, internal ground potential. The KL3021 is characterized by its fine granularity and electrical isolation. An op...
