PRODUCT DESCRIPTION
PEPPERL & FUCHS 097972 - KFD2-SR2-EX1.W Intrinsic Safety Barrier
The PEPPERL & FUCHS KFD2-SR2-EX1.W, identified by part number 097972, is a K-System intrinsic safety barrier engineered for signal conditioning and galvanic isolation of discrete inputs originating from hazardous areas. It functions as a two-channel switch amplifier, providing intrinsically safe power to NAMUR proximity sensors or mechanical contacts and converting their status into isolated relay outputs for safe area control systems, ensuring compliance with explosion protection directives.
