Cranford Controls KFD0-SD2-EX1.1045 Solenoid Driver

The range of isolated barriers that Cranford Controls offer are available to suit most applications for interfacing fire detectors onto conventional and addressable systems as well as driving IS sounders/beacons. Each barrier has been tested and certified so that over voltage on the primary (safe) side of the transformer cannot release energy across the winding to the secondary (hazardous) winding of the transformer.

The use of transformer isolated barriers combined with sounders means that installers may wire both detectors and sounders/beacons with no requirement for an intrinsically safe earth, making for a more simplified and cost-effective approach to hazardous areas. Din rail enclosures are available to suit the requirements of each barrier interface.

This isolated barrier is used for intrinsic safety applications. It supplies power to solenoids, LEDs, and audible alarms located in a hazardous area. 

It is loop powered, so the available energy at the output is received from the input signal. The output signal has a resistive characteristic. As a result the output voltage and current are dependent on the load and the input voltage.

At full load, 10 V at 45 mA is available for the hazardous area application.
