Intrinsically safe voltage
In normal use, electrical equipment often creates tiny electric arcs (internal sparks) in switches, motor brushes, connectors, and in other places. Compact electrical equipment generates heat as well, which under some circumstances can become an ignition source. There are multiple ways to make equipment safe for use in explosive-hazardous areas. Intrinsic safety (denoted by "i" in the ATEX and IECEx Explosion Classifications) is one of several availa… WebA Control Drawing plays an important role in the safe installation, operation, and maintenance of an intrinsically safe system. Intrinsic safety (IS) is a system concept: each IS assembly includes three main, interconnected components: a) An intrinsically safe Field Device (known as the IS device. b) A Safety Barrier (also known as the associated …
