Cranford Controls KFD0-CS-EX2.51P Two Channel Barrier for Conventional Detectors

The KFDO-CS-EX2.51P isolated barrier is used for intrinsic safety applications.

The device transfers DC signals of fire alarms and smoke alarms from the hazardous area to the non-hazardous area. The device can also be used to control I/P converters, valves, indicators, and audible alarms.

A reverse polarity protection prevents damage to the device caused by faulty wiring. The device is loop powered. From the control side no additional power supply has to be connected.

Intrinsic safety barriers from Cranford Control’s limit the energy that is supplied to a circuit and protect hazardous areas from excess energy. By limiting energy to a safe level, intrinsically safe circuits prevent the ignition of potentially explosive atmospheres. This simplifies maintenance and repair of Ex i circuits.
