ОПИСАНИЕ ПРОДУКТА
PEPPERL & FUCHS 295670100269 - 2-Channel Switch Repeater Intrinsic Safety Barrier
This K-System intrinsic safety barrier, corresponding to manufacturer part number KFD2-SR2-EX1.W.LB, provides galvanic isolation and signal conditioning for two independent digital inputs originating from hazardous areas. It converts signals from NAMUR sensors or mechanical contacts into safe-area relay outputs, incorporating comprehensive line fault detection for enhanced system integrity. Engineered for DIN rail mounting within control cabinets, it facilitates reliable process control in environments requiring explosion protection.
