PRODUCT DESCRIPTION
PEPPERL & FUCHS 203351 - K-System Isolated Barrier, Frequency Converter
This intrinsically safe isolated barrier from the K-System series is engineered to convert frequency signals originating from NAMUR proximity sensors or mechanical contacts into proportional analog current and two relay outputs. It provides galvanic isolation between hazardous and safe areas, ensuring robust signal conditioning for process control and safety instrumented systems in industrial applications.
