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 a supply module 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 at a safe extra low voltage!
When using the F I/O module, only use SELV/PELV power supplies per
EN 50178 or IEC 60950-1 for the 24 VDC supply.
Only operate analog inputs at a safe extra low voltage!
Only connect sensors whose output current is generated from a SELV/PELV
power supply to F I/O module inputs.
Only supply PROFIsafe modules with filtered voltages!
F I/O modules must only be supplied with power that does not have any surge
voltages (burst and surge per IEC 61326-3-1 or IEC 61000-7). Install an external
filter or filter module (750-624 or 750-626) to filter out surge voltages. Be sure to
keep the cable length from the filter to the fieldbus node as short as possible.
