The Pepperl+Fuchs KFD2-CRG2-1.D is a high-performance, single-channel isolated barrier from the K-System series, designed for intrinsic safety applications. This current repeater provides galvanic isolation to power 2-wire and 3-wire SMART transmitters or current sources located in hazardous areas, and it accurately transfers the 4-20 mA signal to the safe area. It features line fault detection (LFD) for both open and short circuits in the field circuit, ensuring system integrity. Its compact, DIN rail mountable housing and removable terminals make for easy installation and maintenance in process control and automation systems.
