Becker Mining System smartcom® Intrinsically Safe Isolation Barrier is used to provide an isolated interface between two separately powered “Radiating Leaky Cable Systems”. The IS Barrier is located in the nonhazardous area and provides an RF link and dc power to the hazardous area equipment. Each side of the barrier provides a connection facility for a power supply located in its 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.
