PEPPERL & FUCHS 191243 - K-System Intrinsic Safety Barrier, Analog Input Converter
This K-System intrinsic safety barrier, model KFD2-CD-EX1.32, provides galvanic isolation and signal conditioning for analog inputs originating from hazardous areas. It is engineered to power 2-wire or 3-wire transmitters, current sources, or NAMUR sensors located in Zone 0, 1, or 2, converting their signals into a proportional 4-20mA current output for safe area control systems.
