Hochiki KFD0-CS-EX2.51P Isolated Barrier
The Hochiki KFD0-CS-EX2.51P is an isolated barrier that is used for intrinsic safety applications. It transfers DC signals from fire alarms, smoke alarms, and temperature sensors in hazardous areas. It can also be used to control I/P converters, power solenoids, LEDs, and audible alarms.
Reverse polarity protection prevents damage to the isolator caused by faulty wiring.
Since this isolator is loop-powered, use the technical data to verify that proper voltage is available to the field devices.
