PEPPERL & FUCHS 301018 - K-System Intrinsic Safety Barrier, Switch Repeater
PEPPERL & FUCHS 301018 is a K-System intrinsic safety barrier designed for galvanic isolation and signal conditioning of digital inputs from hazardous areas. This 2-channel switch repeater module facilitates the safe interface of NAMUR sensors or mechanical contacts located in Zone 0, 1, or 2 with control systems in the safe area, ensuring compliance with explosion protection directives. It integrates line fault detection and provides reliable relay outputs for critical process control applications.
