ProfiBUS Ex i -Intrinsically safe apps-
Data Sheets and Resources
- There is a special Profibus specification for safety-orientated intrinsically safe applications. Intrinsic safety is achieved by limiting the energy. At low voltage, this is reflected among other things, by a higher current density in the bus line, as the devices are also supplied with power via the bus line.
- The main factor of this connector is compliance with EN50020.
- The Ex i connectors have been developed in cooperation with ABB and approved for their S900 controller.
