Electrical connection

7.2 Electrical connection
The MA 235i
The voltage supply (PWR IN) as well as the switching inputs/outputs (PWR OUT or PWR IN)
are connected there. The number and function of the switching inputs/outputs is dependent
on the connected end device. Two additional M12 connectors/sockets are used for connec-
tion to the fieldbus. Both of these connections are A-coded.
An internal RS 232 interface is used for connecting the respective Leuze device. Another
internal RS 232 interface functions as a service interface for configuring the connected
device via a serial null modem cable.
