Intrinsically safe signal
Intrinsic safety (IS) is a protection technique for safe operation of electrical equipment in hazardous areas by limiting the energy, electrical and thermal, available for ignition. In signal and control circuits that can operate with low currents and voltages, the intrinsic safety approach simplifies … See more 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 … See more • ATEX directive See more Standards for intrinsic protection are mainly developed by IEC,International Electrotechnical Commission but different agencies also develop standards for intrinsic safety. Agencies may be run by governments or may be composed of members from … See more • Redding, R.J., Intrinsic Safety: Safe Use of Electronics in Hazardous Locations.
