The BECKHOFF KS4428 is a high-density, 8-channel analog output Bus Terminal designed for space-sensitive automation architectures. Operating within the standard Beckhoff K-bus system, this terminal generates analog output signals in the 4 to 20 mA range with a 12-bit resolution. It is engineered to interface directly with actuators, current-loop indicators, valves, and other process control devices that require precise current signals.
A key distinguishing feature of the BECKHOFF KS4428 is its pluggable wiring level. Unlike standard KL-series terminals, the KS-series design allows the terminal connector block to be detached from the housing. This enables pre-wiring of the control cabinet and fast, tool-free replacement of the terminal electronics during maintenance, significantly reducing machine downtime.
With eight single-ended channels housed in a compact 12 mm width, this terminal maximizes packing density on the DIN rail. It leverages the internal K-bus for communication with the coupler or controller and utilizes the 24 V DC power contacts for field-side signal generation.
