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.

The supply voltage for the field side is automatically passed to the next module
via the power jumper contacts when assembling the I/O modules.
The current load of the power contacts must not exceed 10 A on a continual basis.
