Industrial processing systems utilize the BECKHOFF KS3444 analog input bus terminal to interface standard 0 to 20 mA signals directly from the field level to the higher-level automation controller. This four-channel module features single-ended inputs and provides a highly space-efficient design with a pluggable wiring level, enabling fast, tool-free installation and maintenance. By operating directly through the standard K-bus, the unit transmits digitized process values back to the coupler or controller with a 12-bit resolution. Integrated electrical isolation of 500 V between the K-bus and the signal channels guarantees high noise immunity and signal integrity in demanding electrical environments.
