PEPPERL & FUCHS 274121 - K-System Isolated Barrier / Repeater Power Supply
This K-System isolated barrier, identified as KFD2-CD-EX1.PN, functions as a repeater power supply for intrinsically safe applications. It provides power to 2-wire transmitters located in hazardous areas and transfers the analog 4-20mA signal to the safe area, ensuring galvanic isolation between circuits. The unit is engineered for reliable signal conditioning and interface in process automation systems operating in classified hazardous environments.
