Pwr Out Switching Input/Output; Bus In - Leuze electronic MA 204i Technical Description

Electrical connection
7.2.2

PWR OUT switching input/output

PWR OUT
SWIO_2
VOUT 1
SWIO_1
M 12 socket
(A-coded)
Table 7.2:
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.
