ОПИСАНИЕ ПРОДУКТА
PEPPERL & FUCHS 419648 - K-System Isolated Barrier, Current Repeater Power Supply
PEPPERL & FUCHS 419648, identified as the KFD2-CD-EX1.CN, is a single-channel K-System isolated barrier engineered for intrinsic safety applications in process automation. It functions as a repeater power supply and input for 2-wire and 3-wire transmitters or current sources situated in hazardous areas, delivering a galvanically isolated 0/4-20 mA current output to the safe area. This module ensures robust signal integrity and compliance with intrinsic safety standards for critical industrial control systems.
