ArmorPOINT I/O DeviceNet Adapters 13
Publication 1738-IN014D-EN-E - December 2010
Specifications
Attributes Value
Expansion I/O capacity 63 modules max.
Actual number of modules can vary.
Add up current requirements of modules you want to use to make sure they
do not exceed the amperage limit of 1.0 A for the ArmorPOINT I/O
DeviceNet adapter.
Backplane current can be extended beyond 1.0 A with a 1738-EP24DC
Backplane Extension Power Supply. The 1738-EP24DC can supply up to an
additional 1.3 A of backplane current.
Add multiple 1738-EP24DC modules to reach the 63 module max.
