Current requirements
The following table shows the calculation of the total current
consumption for one CP branch line; figures have been
rounded up. Take the current used by the valves and modules
from the relevant technical data in each case.
Current consumption at Pin 1 of the Powerbox
Maximum current consumption of electronics (in-
ternal electronics of all connected CP modules)
+ 560 mA
Current consumption of all connected sensors
(see manufaturer’s data)
+_______A
Total current consumption at Pin 1
=_______A
_______A
Current consumption at Pin 2 of the Powerbox
Current consumption of all solenoid valves
drawing current simultaneously
1)
_______A
Total current consumption at Pin 2
=_______A
+_______A
Current consumption at Pin 1 of the Output module
Current consumption of all simultaneously
activated electrical outputs
(internal consumption at logical 1)
2)
____ x ____A
Load current simultaneous with activated outputs
+_______A
Total current consumption of outputs
=_______A
+_______A
Overall current consumption of CP system
=_______A
1) Current consumption dependent on valve type (see valve technical data)
2) For internal consumption at logical 1 see output module technical data
