Interface Products

Interface technology from Pepperl+Fuchs has always been an established name in the process industry. As a pioneer in the field of intrinsic safety barriers, we build on decades of experience and are the world's leading expert in the field of intrinsic safety. To provide the best possible protection for people, plants, and the environment, we offer an extensive range of modules and systems for a variety of applications—from simple isolator modules for safe signal transmission to highly functional components with numerous additional functions.

A wide range of functions, easy maintenance, and high flexibility: this is what the K-System stands for. Certified worldwide and unsurpassed in reliability, it guarantees maximum process reliability in a large number of industries. Its barrier function limits the energy fed into the intrinsically safe circuit: the galvanic isolation of the measuring and control circuits protects control systems and field devices from interference on the signal path, ensuring the efficiency and availability of the system. With the largest product portfolio of its kind, the K-System is suitable for a wide range of requirements in the process industry and is designed for mixed applications of Ex and non-Ex modules.

The K-System impresses with its high availability due to the low power loss of the modules, comprehensive global support, demand-oriented installation options, and unmatched performance. Reliable signals for optimum processes—always state-of-the-art with interface technology from Pepperl+Fuchs.
