ОПИСАНИЕ ПРОДУКТА
PEPPERL & FUCHS 70124762 - KFD2-CD-EX1.LP Single-Channel NAMUR Switch Amplifier
This single-channel intrinsically safe switch amplifier from the PEPPERL & FUCHS K-System series is engineered for precise signal conditioning of NAMUR sensors in hazardous area applications. It provides galvanic isolation between the hazardous and safe areas, converting sensor signals into a potential-free relay output for control systems, and incorporates line fault detection for operational integrity.
