Isolated Barriers (K-System)

K-System interface technology

Solving a wide range of applications in one system, our K-System guarantees a reliable and economical signal transmission between your field device and the control system. Whether your plans include a single isolating module or a large scale system integration, application-oriented solutions characterize the entire K-System product range.


Product portfolio

K-System offers an extensive range of intrinsic safety interface modules for many signals and applications - from simple isolators to highly functional modules.


Power Rail

The Power Rail is an insert in the standard 35mm DIN rail. When mounting on the DIN rail, the units are simply snapped in place. The Power Rail supplies the modules with power and provides a path for the collective error message from individual isolators. Power Rail reduces wiring and maintenance costs because it eliminates the need to daisy chain the wires. It also simplifies expansion. Just snap in a new module when you're ready to add to your system.
