BASIC INFO
Pepperl+Fuchs Switch Amplifier KFA5-SR2-Ex2.W K System Modules Isolated Barriers
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.
