3.6.3.1 Connection
Sensors and actuators can be directly connected to the relevant channel of the I/O
module in 1, 2, 3 or 4 conductor connection technology. The I/O module supplies
power to the sensors and actuators. The input and output drivers of some I/O
modules require the field side supply voltage.

The fieldbus coupler/controller provides field side power (DC 24 V). In this case
it is a passive power supply without protection equipment.

Power supply modules with or without fuse holder and diagnostic capability are
available for the power supply of other field potentials (DC 24 V, AC/DC 0 …
230 V, AC 120 V, AC 230 V). The power supply modules can also be used to set
up various potential groups. The connections are connected in pairs to a power
contact.
