Power Supply
WAGO-I/O-SYSTEM 750
ETHERNET TCP/IP
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.
