PEPPERL & FUCHS 450065 - K-System Isolated Barrier, Frequency Converter
This K-System isolated barrier, identified as KFD2-CD-EX1.32, functions as a frequency converter and signal conditioner for intrinsically safe applications. It processes digital input signals from NAMUR sensors or mechanical contacts in hazardous areas, converting them into isolated analog, relay, and passive transistor outputs for safe area control systems. The module is engineered for reliable signal transmission and frequency monitoring in process automation and safety instrumented systems (SIS).
