Attention
Resetting the system by switching on and off the system supply, must take
place simultaneously for all supply modules (coupler/controller and
750-613).
2.7.2.2 Alignment
Recommendation
A stable network supply cannot be taken for granted always and everywhere.
Therefore, regulated power supply units should be used in order to guarantee
the quality of the supply voltage.
The supply capacity of the coupler/controller or the internal system supply
module (750-613) can be taken from the technical data of the components.
Internal current consumption
*)
Current consumption via system voltage:
5 V for electronics of the bus modules and
coupler/controller
Residual current for bus
terminals
*)
Available current for the bus modules. Provided by
the bus power supply unit. See coupler/controller
and internal system supply module (750-613)
*)
cf. catalogue W4 Volume 3, manuals or internet
Example Coupler 750-301:
internal current consumption:350 mA at 5V
residual current for
bus modules : 1650 mA at 5V
sum I
(5V) total
: 2000 mA at 5V
The internal current consumption is indicated in the technical data for each bus
terminal. In order to determine the overall requirement, add together the
values of all bus modules in the node.
Attention
If the sum of the internal current consumption exceeds the residual current
f
or bus modules, then an internal system supply module (750-613) must be
placed before the module where the permissible residual current was
exceeded.
