7.2.2 PWR OUT switching input/output
Notice!
The maximum admissible current of the PWR OUT and IN connectors is maximum 3A. To
be subtracted from this is the current consumption of both the MA and of the connected
end device.
The function of the switching inputs and outputs is dependent on the connected Leuze device.
Detailed information on this topic can be found in the respective operating instructions.
On delivery, the SWIO 1/2 are connected in parallel on PWR IN/OUT. This connection can
be separated with a jumper.
7.3 BUS IN
The MA 248 i makes a PROFINET-IO interface available as host interface.


For the host connection of the MA 248 i , the "KB ET - … - SA-RJ45" ready-made cables
are preferred, see table 14.4 Bus connection cable for the MA 248i on page 84.
