Intrinsically Safe Barrier Relays
Intrinsically safe control circuits provide a safe and cost-effective method for interfacing electrical control devices that span across hazardous and non-hazardous locations. Safety is ensured at these interfaces using intrinsically safe barrier devices.
When designing Intrinsically Safe Circuits, it is imperative to understand the entity parameters of the devices in your circuit. The entity parameters describe characteristics of the device, as well as what can safely be connected to it.
When electrical equipment is used in, around, or near an atmosphere that has flammable gases or vapors, flammable liquids, combustible dusts, ignitable fibers or flyings, there is a possibility or risk that a fire or explosion might occur.
