Introduction

Introduction 1:
KL3404 and KL3464

The KL3404/KS3404 and KL3464/KS3464 analog input terminals process signals in the ranges -10 V to +10 V or 0 V to 10 V. The voltage is digitized to a resolution of 12 bits, and is transmitted, electrically isolated, to the higher-level automation device. In these Bus Terminals, the four inputs are 2-wire versions and have a common ground potential. This reference ground of the inputs is electrically isolated from the 0 V power contact. The power contacts are connected through. The LEDs indicate the data exchange with the Bus Coupler.
