Hello Hike; If you are willing to put a little effort in it, this introduction to explosion protection and standards should be a good place to start: SIMATIC Principles of Explosion Protection You will find there descriptions of explosive area nomenclature, protection levels and standards. For example: Then you could continue by having a look at some Siemens EX IO modules, in this case for the ET 200M Platform: SIMATIC Automation Systems S7-300, ET 200M Ex I/O Modules Hope this helps, Daniel Chartier |
