PRODUCT DESCRIPTION
PEPPERL & FUCHS 240780100008 - KFD2-SR2-EX1.W Intrinsic Safety Switch Repeater Barrier
The PEPPERL & FUCHS KFD2-SR2-EX1.W (Order No. 240780100008) is a K-System intrinsic safety barrier engineered for galvanic isolation and signal conditioning of digital inputs originating from hazardous areas. It functions as a two-channel switch repeater, providing potential-free relay outputs in the safe area based on signals from NAMUR proximity sensors or mechanical contacts located in Zone 0, 1, or 2 environments. This module ensures reliable signal transmission while maintaining intrinsic safety for critical process automation applications requiring explosion protection.
