ОПИСАНИЕ ПРОДУКТА
PEPPERL & FUCHS 309730 - KFD2-CD-EX1.CN Intrinsic Safety Barrier, Frequency Converter/Splitter
This K-System intrinsic safety barrier, model KFD2-CD-EX1.CN, provides galvanic isolation and signal conditioning for digital inputs originating from hazardous areas. It converts frequency signals from NAMUR sensors or dry contacts into two proportional analog current outputs and two relay outputs for safe area control systems. Engineered for robust performance in process automation, it ensures reliable signal transmission and certified explosion protection for critical instrumentation.
