Intrinsic safety certifications

What information do I need to obtain Intrinsic safety certifications?

Digi radio modems have been integrated by a number customers into products that are used in hazardous environments. For electronic equipment to be used in environments with combustible gases present it is often necessary for the final product to receive a UL certification for Hazardous locations.

 
These locations are rated by how hazardous they are. Class 1 Division 1A (C1D1A) is the most dangerous location. An example of a C1D1A location would be a location in direct contact with acetylene gas. The area close to an unleaded gasoline pump is usually considered a C1D2 location.
 
All electronic equipment to be used in these locations must be tested by an independent lab and certified to be safe for use. They generally look at the schematics of the equipment to verify that even in a failure condition the equipment will not create a spark that could ignite the hazardous atmosphere.
 
If an OEM needs to obtain this certification for a product containing one of the following modules, they can provide the following information to the independent test lab instead of a schematic:
