Power Supply Concept

The F I/O module receives the field supply voltage via the power jumper contacts
listed as knife blade contacts from an upstream I/O module, the fieldbus
coupler/controller or an internal system power supply and makes this potential
available via the power jumper contacts listed as spring contacts for downstream
I/O modules.
Only operate F I/O modules with safe extra low voltage!
When using F I/O modules, only use power supplies with extra-low voltage
(PELV/SELV) for the 24 VDC power supply acc. EN 50178 or EN 60950-1.
In addition, note that only a maximum voltage of U
I/O modules even in the event of failure.
The following applies to all F I/O modules:

Only operate sensors and actuators with a safe extra low voltage!
All sensors and actuators with field supply connected to the F I/O modules also
have to be supplied from a safe extra low voltage (SELV/PELV). In the case of
error, only the maximum voltage U
a F I/O module.
The following applies to the maximum voltage U

Only supply F I/O modules with filtered voltages!
Only power a fieldbus node that contains F I/O modules with a voltage filtered
against surges (burst and surge) according to EN 61326-3-1. You may need to
install an external Field Supply Filter or Supply Filter (750-624 or 750-626). Note
that the cable length from the filter to the fieldbus node must be as short as
possible.
