Specifications
Following are specifications for the 1738 ArmorPoint DeviceNet
adapters.
ArmorPoint DeviceNet Adapters - 1738-ADN12, -ADN18, -ADN18P, and -ADNX
Expansion I/O Capacity
• DeviceNet adapter backplane current output = 1.0 A maximum. See the following list for
backplane current consumption for each ArmorPoint I/O catalog number and the current
consumption for each of the ArmorPoint modules connected to the ArmorPoint
DeviceNet adapter. Verify that it is below 1.0 A.
• 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.
• Multiple 1738-EP24DC modules can be used to reach the maximum of 63 modules.
