Becker Mining Systems smartcom® Intrinsically Safe Isolation Barrier is used to provide an isolated interface between the base station; a ‘Radiating Leaky Feeder Cable Systems located in the non-hazardous area, and a “Radiating Leaky Cable System” located in the hazardous area. The Barrier provides an ac link but no dc power passes between the
two sides of the interface. Each side of the barrier provides a connection facility for a power supply located in the respective location. The safe area terminals are for connection to a non-intrinsically safe power supply and the hazardous area terminals are for connection to an intrinsically safe power supply.

The primary purpose of the IS Isolation Barrier is to isolates the hazardous area equipment from the safe-area equipment. The safe area terminals are for connection to non-intrinsically safe Leaky Feeder equipment and the hazardous area terminals are for connection to intrinsically safe Leaky Feeder equipment. This leaky feeder unit is NOT to be used in hazardous areas for example to replace a Cell Coupler.

The equipment is comprised of a single PCB which is encapsulated inside a certified glass fiber reinforced polyester enclosure. The IS Barrier has two RF connections for simple
installation of coaxial radiating cables.
