K-SYSTEM THE MOST TRUSTED NAME
With its convincing advantages from the planning to the service of your asset our K-System
guarantees a reliable and economical signal transmission between your field devices and the control
system. The flexible, demand-oriented possibilities of installation from the single module to the
system solution for the building of a large scale plant characterise the K-System. For intrinsic safety
applications, the control and field circuits are galvanically isolated from one another.
For Non-IS applications, the K-System provides cost optimised versions without Ex-Protection.
THE SYSTEM MECHANICS
User-friendly:
Modular housing with removable screw terminals
Handles thick and thin:
Appropriate to conductor profiles up to 2.5 mm/14 AWGSaves time and costs:
Voltage supply and collective fault message via Power Rail
Secure:
Flame resistant according to UL94 V-0
Compact:
Width of standard housing from 12.5 mm up to 40 mm
Adaptive:
Location independent vertical or horizontal mounting,
since no ventilation slots are necessary
From cold to hot:The K-System can be operated from -20 C to +60 C

Pepperl+Fuchs is the leading supplier of intrinsic safety barriers in the world and our K-System line of isolators
supports this fact. K-System is easy to specify, integrate and expand and has become synonymous with safety
and reliability. Our extensive line of isolators contains over 150 different models, each containing industry leadingfeatures and benefits.
The 12.5 mm KC-Modules as the well-proven 20 mm barriers of the KF-Modules contain the characteristics of the
K-System. This collection provides you a wide range of interface barriers, which you can combine individually on
the Power Rail.
