This listing is for a Pepperl+fuchs KFD0-CS-Ex1.54 Isolated Repeater Barrier, a crucial component of the K-System designed for Intrinsic Safety applications. This single-channel isolated barrier is specifically engineered to provide control and signal transfer for SMART compatible fire and smoke alarm transmitters located within hazardous areas. It operates by transferring an analog current input (1 mA to 20 mA) from the hazardous area to the safe area as an isolated value. The unit is loop-powered and capable of bi-directional transfer of digital signals superimposed on the analog values (such as HART communication). It is rated up to sil 3 (Safety Integrity Level 3) according to IEC/EN 61508, making it a reliable choice for high-integrity safety systems in industrial environments. The un.
