The R Stahl 9001 Series Intrinsic Safety barriers are for protection and accuracy for intrinsically safe sensing and controlling devices in hazardous locations. The electronic design limits the amount of electrical energy that can be transmitted into the hazardous area to a level below the ignition energy of even the worst-case explosive mixture of fuel and air. This level of protection remains intact even in the event of simultaneous faults, thus providing the highest possible safety rating for this type of system.
