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 diagnostic capability are available for the
power supply of other field potentials (e.g. 24 VDC, 0 VAC/DC ... 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.

The field-side power supply is automatically derived from the power jumper
contacts when snapping an I/O module.
The current load of the power contacts must not exceed 10 A on a continual basis.
