DIP Switch Configuration

Now approved for use in Class I Div 2 Group A, B, C, D areas!
Users can now have significant labor savings over traditional protection methods because there is no need for explosion proof enclosures and conduits.

A Class I hazardous location is one in which flammable gases or vapors may be present in the air to be ignitable or explosive. (Typical applications include petroleum refineries, spray finishing areas, utility gas plants and fuel servicing areas.)

A Division 2 area is one where the flammable gases or vapors are normally not present in an explosive concentration, but could accidentally exist.

Group A is Acetylene, Group B includes Hydrogen, Group C includes Ether and Group D includes Hydrocarbons, fuels and solvents.
