ERbic Profibus Ex i
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.
With regard to the connector, the main factor is compliance
with EN 50020. For example, defined clearance and creepa-
ge distances and current carrying capacity must be taken into
account. These Ex i connectors have been developed in coo-
peration with ABB and approved for their S900 controller. The
individual connector alone does not require separate appro-
val. This must always be given in conjunction with the system
in accordance with the relevant directives and standards.

ERbic connectors are passive components and do not need
to be identified with the CE marking according to EU direc-
tives.
* Due to continuous advancement, it is possible that the UL approval of a new version may not have been completed at the time of going
to press.
