Pepperl amp Fuchs KFD0-CS-EX2.54 Repeater
Pepperl Fuchs KFD0-CS-EX2.54 RepeaterThis isolated barrier is used for intrinsic safety applications. It provides control and signal transfer for SMART compatible fire and smoke alarm transmitters inside hazardous areas. Digital signals may be superimposed on the analog values in the hazardous or safe area and are transferred bidirectionally. The fall time of the digital signal must be less than 50 s the current in the hazardous area must be bigger than 1 mA. Since this isolator is loop-powered use the technical data to verify that proper voltage is available to the field devices.Details2-channel isolated barrier24 V DC supply loop poweredSMART fire alarm inputCurrent input 1 mA ... 20 mAUp to SIL 3 acc. to IECEN 61508
