Connection
The WAGO-I/O-SYSTEM 750 requires a 24 V direct current system supply.
The power supply is provided via the fieldbus coupler/controller and, if necessary,
in addition via internal system supply modules 750-613. The power supply is
reverse voltage protected.
Do not use an incorrect voltage/frequency!
The use of an incorrect supply voltage or frequency can cause severe damage to
the components.

System supply DC 24 V (-25 % … +30 %)
2
System supply 0 V
The fed DC 24 V supplies all internal system components, e.g. fieldbus
coupler/controller electronics, fieldbus interface and I/O modules via the internal
bus (5 V system voltage). The 5 V system voltage is galvanically connected to the
24 V system supply.
