ОПИСАНИЕ ПРОДУКТА
PEPPERL & FUCHS 231221 - KFD2-SR2-EX1.W Intrinsically Safe Isolated Barrier
The PEPPERL & FUCHS KFD2-SR2-EX1.W is a single-channel intrinsically safe isolated barrier from the K-System, engineered for the reliable processing of switching signals originating from hazardous areas. It provides galvanic isolation between the hazardous and safe areas, driving a relay output to interface with control systems while maintaining intrinsic safety for applications in process control and safety instrumented systems.
