Intrinsic safety barriers are the core of Pepperl+Fuchs' product portfolio. We offer the widest selection of products for protection of electrical signals located in hazardous areas. These intrinsic safety modules combine the energy limiting features of a zener barrier with galvanic isolation. Pepperl+Fuchs offers systems for different applications and mountings.
Our most popular intrinsic safety isolated barriers are the flexible DIN rail mounted K-System modules. The K-System intrinsic safety barriers connect easily with our Power Rail assembled in the DIN rail. The use of the Power Rail reduces the wiring by energizing the modules mounted on the DIN rail.
The intrinsic safety isolated barriers of the H-System are mounted on termination boards. This innovative product is ideal for applications requiring tight DCS or system integration.
For rack mounted isolated barriers, Pepperl+Fuchs offers a wide range of Eurocards in the E-System. You can choose between 3 variations of Eurocards.
The WE-System isolated switch amplifiers provide power to NAMUR proximity sensors or dry contacts located in hazardous environments. The units can be installed onto a DIN-Rail or by mounting them with screws through holes in the base. For new installations we recommend to use our K-System isolated barriers.
