I have AB 1734- Point I/O
In this particular case, I intend on using 1734-EPAC module to power adjacent modules (to the right). The manuals express a limit of 1.3A on the POINTBus. Is this 1.3 Amp the total power that can be supplied from the card? I am confused... I found another manual that identifies the PointBus current for each card, but shouldn't that value vary depending on how much load I have on the output modules?
Or maybe there are several buses on the back plane and each bus is rated for 1.3 Amps? If that is the case, how many buses are there?
For reference, power supplies:
