PRODUCT DESCRIPTION
PEPPERL & FUCHS 087119 - KFD2-SR2-EX1.W.SM Safety Relay / Switch Amplifier
This K-System series intrinsic safety barrier functions as a 2-channel switch amplifier, designed for reliable signal conditioning and safety interlocking in hazardous area applications. It provides galvanic isolation between the safe and hazardous areas, converting signals from NAMUR sensors or mechanical contacts into safe relay outputs for process control and emergency shutdown systems.
