Applying electronic controls in hazardous environments can be difficult. Fortunately, Littelfuse SymCom intrinsically safe relays and controllers are specifically designed to interface controls between hazardous and non-hazardous areas. Intrinsically safe relays limit the energy that is provided to the hazardous area, thus reducing the potential of a spark. SymCom provides several models of intrinsically safe relays and controllers offering distinct output relay configurations for a variety of systems.
