Field Supply
3.5.4.1 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 (24 VDC,
0 … 230 VAC/DC, 120 VAC, 230 VAC). The power supply modules can also be
used to set up various potential groups. The connections are connected in pairs
to a power contact.
