7.2.2 PWR OUT switching input/output
Notice!
The maximum admissible current of the PWR OUT and IN connectors is maximum 3 A. 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 255 i provides a DeviceNet interface as a HOST interface.
Table 7.3: Pin assignments for DeviceNet BUS IN

For the host connection of the MA 255 i , the ready-made KB DN/CAN-xxxxx-Bx cables
are preferred, table 14.5 "Bus connection cable for the MA 255i" on page 80.
