PRODUCT DESCRIPTION
PEPPERL & FUCHS 911271 - Intrinsic Safety Barrier - Switch Amplifier
This K-System series intrinsic safety barrier, identified as KFD2-SR2-EX1.W.SM, is a two-channel switch amplifier engineered for interfacing hazardous area sensors with safe area control systems. It provides galvanic isolation and intrinsically safe power to NAMUR proximity sensors or mechanical contacts, converting their status into isolated relay outputs for robust process control applications.
