PRODUCT DESCRIPTION
PEPPERL & FUCHS 030348 - KFD2-SR2-EX1.W Intrinsic Safety Barrier / Switch Amplifier
This is a 2-channel intrinsic safety barrier from the K-System series, engineered to provide galvanic isolation and signal conditioning for NAMUR sensors or mechanical contacts located in hazardous areas. It converts digital input signals into isolated relay outputs for safe area control systems, incorporating line fault detection and high functional safety for critical process automation applications.
