PRODUCT DESCRIPTION
PEPPERL & FUCHS 025998 - K-System 1-Channel Isolated Barrier
The PEPPERL & FUCHS KFD2-CD-EX1.PN is a 1-channel isolated barrier from the K-System series, engineered for intrinsic safety applications. It provides galvanic isolation and signal conditioning for NAMUR proximity sensors or mechanical contacts located in hazardous areas, transmitting their status to safe area control systems via relay and passive transistor outputs. This device facilitates reliable signal transfer in process automation environments requiring compliance with intrinsic safety standards.
