PEPPERL & FUCHS 072175 - KFD2-SR2-EX1.W.SM Intrinsic Safety Barrier / Switch Amplifier
The PEPPERL & FUCHS KFD2-SR2-EX1.W.SM is a 2-channel intrinsic safety barrier and switch amplifier from the K-System series, engineered for reliable signal conditioning between hazardous and safe areas. It provides intrinsically safe circuits for NAMUR proximity switches or dry contacts, converting these inputs into isolated relay outputs for integration into control systems and safety instrumented functions.
