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.
Data transmission rate: According to bus specification, 12 Mbit/s.
Termination type: Screw terminal
