Introduction 1:
KL3001, KL3002

The KL3001 and KL3002 analog input terminals process signals in the range between -10 V and +10 V. The voltage is digitized to a resolution of 12 bits, and is transmitted, electrically isolated, to the higher-level automation device. The input channels of the Bus Terminals have differential inputs and possess a common, internal ground potential. The LEDs indicate the data exchange with the Bus Coupler.
