System Supply; Connection - WAGO I/O System 750 Series Manual

2.7.2 System Supply

2.7.2.1 Connection

The WAGO-I/O-SYSTEM 750 requires a 24 V direct current system supply
(-15% or +20 %). The power supply is provided via the ECO coupler and, if
necessary, in addition via the internal system supply modules (750-613). The
voltage supply is reverse voltage protected.
Attention
The use of an incorrect supply voltage or frequency can cause severe damage
to the component.
Fig. 2-11: System Supply
The direct current supplies all internal system components, e.g. ECO coupler
electronics, fieldbus interface and bus modules via the internal bus (5 V sys-
tem voltage). The 5 V system voltage is electrically connected to the 24 V sys-
tem supply.
