Process control and automation networks requiring precise analog current loop signals utilize the Beckhoff KS4012 analog output terminal to interface with industrial actuators. This 2-channel analog output module delivers accurate signals in the range of 0 to 20 mA with a high-accuracy conversion resolution of 12 bits. The KS-series configuration features a pluggable wiring level, enabling rapid block installation, simplified maintenance, and field-pre-wiring without disconnecting individual signal lines. The module processes electrical analog current signals dynamically by converting digital values from the K-bus backplane with galvanic isolation, ensuring signal integrity in electrically noisy industrial environments.
