■
Fieldbus Power Supply: DC 12 V; 6 W
NOTE
The
BMF
does not require any additional power supplies as it is supplied over the cascade plug and
not from the fieldbus.
NOTE
FBS
modules always need to be supplied with external power as they require an AC 24 V power
supply (the power supply for the fieldbus is DC 12 V). Therefore, the fieldbus length is not limited for
FBS modules.
