The 1734-AENT adapters have the following general specifications.
General Specifications
Attributes Description
Expansion I/O capacity, max •63 modules
•Up to 5 rack-optimization (for digital modules only) and/or
enhanced rack-optimization (for digital, analog, and specialty
modules) connections
•31 direct connections
(1)
•Backplane current output = 1.0 A.
•Actual number of modules can vary.
•Add together the current requirements for the modules you want
to use to make sure they do not exceed the amperage limit of 1.0 A
for the adapter.
•Backplane current can be extended beyond 1.0 A by 1734-EP24DC
or 1734-EPAC backplane extension power supplies.
•Add multiple 1734-EP24DC or 1734-EPAC modules to reach the 63
module max.
(1) Maximum 31 direct connections for standard I/O or maximum 20 direct connections if any safety I/O module
resides in the backplane.
