Separating instruments For power supply and separation in Ex applications Functional principle Separating instruments separate intrinsically safe circuits from non-intrinsically safe circuits. Differences are the kind of voltage supply as well as the size of Ex-technical characteristics values. Applications These instruments are used in all applications where Ex-regulations have to be met. Apart from the power supply in the field, they provide a galvanic separation to the connected PLC or control system. 4 … 20 mA Overvoltage arresters Protection against overvoltages Functional principle...
