Calculation
The following tables show how to calculate the current conĆ
sumption of the system supply and the additional supplies.
Please refer to the relevant technical specifications for the
current consumption of the valves and modules.
System supply type CPX−(M−)GE−EV−S...
Current consumption of the operating voltage supply for the electronics and sensors
CPX bus node current consumption (rounded)
approx. 200mA
Maximum current consumption of the CPX modules supĆ
plied via the system supply (internal electronics)
1)
+ _____ A
Current consumption of the sensors supplied via the sysĆ
tem supply (see manufacturer’s specifications)
+ _____ A
Current consumption of the technology modules supĆ
plied
2)
+ _____ A
Sum of the current consumption of the operating voltage
= _____ A
______ A
Current consumption of the load voltage supply for valves and outputs
Current consumption of all simultaneously activated
electric outputs that are supplied via the system supply
(internal consumption at logic 1)
3)
_____ x _____A
Load current of simultaneously activated outputs supĆ
plied via the system supply
+ _____ A
Current consumption of all simultaneously energised
valve coilsĂ
4)
+ _____ A
Current consumption of the technology modules supĆ
plied
2)
+ _____ A
Sum of the current consumption of the load voltage
= _____ A
+ ______ A
Total current consumption of the system supply
= ______ A
1)
See technical specifications of the I/O modules, pneumatic modules and MPA modules
2)
Including further modules and components supplied via the technology module
3)
Internal consumption at logical 1 see technical specifications for the output module
4)
Current consumption depends on valve type (see technical specifications of the valves)
