Power Supply
WAGO-I/O-SYSTEM 750
Linux Fieldbus Coupler
Example:
A node with a PROFIBUS Coupler 750-333 consists of 20 relay
modules (750-517) and 10 digital input modules (750-405).
Current consumption:
20* 90 mA = 1800 mA
10* 2 mA = 20 mA
Sum 1820 mA
The coupler can provide 1650 mA for the bus modules. Consequently,
an internal system supply module (750-613), e.g. in the middle of the
node, should be added.
Recommendation
With the WAGO ProServe® Software smartDESIGNER, the assembly of a
field bus node can be configured. The configuration can be tested via the
integrated accuracy check.
The maximum input current of the 24 V system supply is 500 mA. The exact
electrical consumption (I
(24 V)
) can be determined with the following formulas:
Coupler/Controller
I
(5 V) total
= Sum of all the internal current consumption of the connected
bus modules
+ internal current consumption coupler/controller
750-613
I
(5 V) total
= Sum of all the internal current consumption of the connected
bus modules
Input current I
(24 V)
=
5 V / 24 V * I
(5 V) total
/ η
η = 0.87 (at nominal load)
Note
If the electrical consumption of the power supply point for the 24 V-system
supply exceeds 500 mA, then the cause may be an improperly aligned node
or a defect.
During the test, all outputs, in particular those of the relay modules, must be
active.
