PRODUCT DESCRIPTION
PEPPERL & FUCHS 251800 (KFD2-SR2-EX1.W.SM) - K-System Intrinsic Safety Barrier
This K-System intrinsic safety barrier, identified as KFD2-SR2-EX1.W.SM, functions as a switch amplifier for the safe operation of field devices in hazardous areas. It provides galvanic isolation between intrinsically safe and non-intrinsically safe circuits, converting signals from NAMUR proximity sensors or mechanical contacts into potential-free relay outputs for control system integration. Engineered for process automation, it ensures compliance with intrinsic safety standards for critical applications.
