Rockwell Automation 1738-ACNR ArmorPoint ControlNet Adapter, Series A - Manual (Page 10)

Publication 1738-IN016B-EN-E - March 2005
10 ArmorPoint ControlNet Adapter, Series A
Specifications Following are specifications for the 1738 ArmorPoint ControlNet
adapter.
ArmorPoint Control Adapter - 1738-ACNR
Expansion I/O Capacity
• Maximum of 63 modules
• Maximum of 5 Rack Optimized connections (for digital modules
only)
• Maximum of 25 Direct connections
• 1738-ACNR backplane current output = 1.0A maximum. See
the list below for backplane current consumption for each
ArmorPoint I/O catalog number and the current consumption
for each of the ArmorPoint modules connected to the
1738-ACNR. Verify that it is below 1.0A.
• Backplane current can be extended beyond 1.0A with a
1738-EP24DC Backplane Extension Power Supply. The
1738-EP24DC can supply up to an additional 1.3A of backplane
current.
• Multiple 1738-EP24DC modules can be used to reach the
maximum of 63 modules.
