PRODUCT DESCRIPTION
PEPPERL & FUCHS 267075-100377 - KFD2-SR2-EX1.W Intrinsic Safety Barrier Switch Amplifier
This PEPPERL & FUCHS K-System intrinsic safety barrier, identified as the KFD2-SR2-EX1.W, is a dual-channel switch amplifier engineered for galvanic isolation and signal conditioning between hazardous and safe areas. It enables the secure connection of NAMUR proximity sensors or mechanical contacts from Zone 0/1/2 hazardous locations to control systems in the safe area, ensuring compliance with intrinsic safety standards. The module provides reliable potential-free relay switching outputs for critical process control and safety instrumented system applications.
