Product Description
The Pepperl+Fuchs KFD2-SCD2-EX1.LK is a 1-channel SMART current driver and isolated barrier, engineered for intrinsically safe analog output applications in hazardous areas. It delivers a precise 4–20 mA current output to drive SMART I/P converters, electrical valves, and positioners, ensuring reliable operation in critical process automation environments.
This module supports HART-IP communication, allowing bi-directional digital signals to be superimposed on the analog output. Moreover, it features line fault detection (LFD), test sockets on terminals, and galvanic isolation to guarantee both safety and accuracy. Its compact DIN rail design simplifies integration into control panels, while SIL 2 (SC 3) certification confirms compliance with IEC/EN 61508 standards.
