Test & measurement Control engineering in the mining industry, chemical industry and refineries --Supply voltage control- Applications EXPLOSIVE ATMOSPHERES PART APPROVAL Often times electronic equipment is required to carry out certain functions in potentially explosive atmospheres. To prevent potential igniting via a spark or arc in these environments, all components must be selected very carefully. Components meeting these requirement are generally referred to as intrinsically safe. These components must be tested such that they will not become an ignition point when subjected to short circuits or adjacent component failures. They must also switch to a defined state when subjected to overload conditions.Our 522-03-i, 525-03-i, 535-04-i, and 567-70-1-1 Opto-coupler series are all ideal for this environment.
