Intrinsically safe warning signaler (powered from nonintrinsically safe voltage source) ISO-*/N are used in control and signaling circuits of mining machinery. Device is used to generate optical and acoustical alarm, warning and informational signals. Signalers meet the requirements of the European Directive 2014/34/UE (ATEX) for equipment in group I, category M2, and can be used in methane and coal dust explosion hazardous areas of underground mines.
ISO-*/N signalers are produced in four different versions:
Choice of generated signal is made with a switch type “DipSwitch”, or using digital transmission
(versions: ISO-*/TR/N). Signaler generates acoustic signals. It also generates optical signals in colors red and yellow. For special order signalers might generate optical signal in colors green, red and yellow (in this case yellow color is combination of red and green glowing simultaneously). Signalis triggered by either contact input or through digital transmission. The signaler is equipped with two relay outputs, one intrinsically safe, one non-intrinsically safe allowing to control other equipment. Using digital transmission, you can control these outputs independently.
