1734-AENT backplane current output = 1.0A.

The actual number of modules can vary. Add up the current 

requirements of the modules you want to use to make sure they do 

not exceed the amperage limit of 1.0A for the 1734-AENT. 

Backplane current can be extended beyond 1.0A by using 

1734-EP24DC backplane extension Power Supplies. Add multiple 

1734-EP24DC modules to reach the 63 module maximum).
