Barrier circuit with an intrinsically safe barrier a simple analogy is a restriction in a water pipe with an overpressure shutoff valve. Web this isolated barrier is used for intrinsic safety applications. Web our intrinsic safety modules connect intrinsically safe rated equipment, such as transmitters, solenoids, proximity sensors and encapsulated assemblies, with control.
