Pepperl Fuchs KFD0-CS-Ex1.54-Y2 SMART Fire Alarm Repeater (241590)
P&F KFD0-CS-Ex1.54-Y2 is a loop-powered 1-channel isolated barrier designed for SMART-compatible fire and smoke alarm systems in hazardous areas. It supports current signals from 1 mA to 20 mA and enables reliable communication between a fire detector loop and control panels—typically via System Sensor® translator devices like the IST200. The unit transfers analog and digital signals bidirectionally and is optimized for fast signal transmission with intrinsic safety up to Zone 0.
