PRODUCT DESCRIPTION
PEPPERL & FUCHS 3261610123 - KFD2-SR2-EX1.W Switch Amplifier Isolated Barrier
The PEPPERL & FUCHS KFD2-SR2-EX1.W is a 1-channel isolated barrier switch amplifier from the K-System series, designed for intrinsic safety applications. It conditions signals from NAMUR sensors or mechanical contacts located in hazardous areas, providing a galvanically isolated relay output to the safe area control system. This module ensures reliable signal transmission and functional safety in critical process automation environments.
