PRODUCT DESCRIPTION
PEPPERL & FUCHS 240776100011 - KFD2-SR2-EX1.W Isolated Barrier
This K-System isolated barrier provides intrinsic safety for two-channel switching signals originating from hazardous areas. It conditions signals from NAMUR sensors or mechanical contacts, converting them into non-intrinsically safe relay outputs for safe area control systems. Engineered for process automation, it ensures reliable signal transmission while maintaining explosion protection in critical industrial environments.
