8 Engineering of a JX3 Station Equipped With a Bus Node JX3-BN-ETH
Engineering Steps
Example
152
When engineering a JX3 Station, proceed as follows:
Step
1
Gather the following information from the Technical Data contained in the
manual of your JX3 module:

Current consumption from the logic voltage of the JX3 system bus:
I
5V

Current consumption from the additional voltage of the JX3 system
bus: I
24V
2
Calculate the power consumption of the JX3 modules:
3 Add the power consumption of JX3 modules included in the JX3 station.
Start with the first JX3 module connected to the JC-3xx controller, or
JX3-BN-xxx bus node.
4
Check whether the allowed power consumption has been exceeded.
5
the allowed power consumption P
has been reached,
the allowed power consumption
P has been reached,
24V
8 JX3 modules have been
connected,
16 JX3 modules have been
connected,
16 JX3-AO4 modules with HW revision 1.xx are connected to a JC-3xx
controller. The limitations to be taken into account when engineering a
JX3 Station apply to these JX3-AO4 modules.
Step
1 Determine the current consumption of JX3-AO4 modules given in the
Technical Data:

Current consumption from the logic voltage of the JX3 system bus:
220 mA

Current consumption from the additional voltage of the JX3 system
bus: 20 mA
2 Calculate the power consumption of a JX3-AO4 module:
3 Add the power consumption of n JX3-AO4 modules:
