Track SA Power Bus Current Draw
We recommend that you track the SA power bus current draw, max, per
module, and collectively for the adapter and I/O modules installed with it.
Consider the following with this example:
• The values in this example represent a worst-case calculation. That is, all
modules that draw SA power bus current, draw the maximum available
on the module.
• Not all modules that are shown in Figure 4
use SA power bus current.
For example, the 5069-ARM and 5069-OW4I modules only pass SA
power bus current to the next module. Some other Compact 5000 I/O
modules do not use SA power bus current, but are not shown in the
graphic, for example, the 5069-OB16 module.
• System SA power bus current, max, is calculated as each module draws
SA power bus current.
In the example in Figure 4
, after the 5069-IB16 module in slot 1 draws
SA power bus current, the system SA power bus current, max, is
138 mA. After the 5069-IB16 module in slot 2 draws SA power bus
current, the system SA power bus current draw is 266 mA.
This process continues until the system SA power bus current, max,
is 1.222 A.
