The Allen-Bradley 1738-AENTR ArmorPoint I/O EtherNet/IP Adapter is a two-port ArmorPoint I/O Ethernet/IP gateway that provides two M12 EtherNet/IP connectors for pass-through, enabling daisy-chain or ring topology to ArmorPoint I/O devices on the EtherNet/IP network. As a Series A ArmorPoint adapter, it is powered from a field-side 10–28 V DC supply (nominally 24 V DC), drawing about 30 mA and consuming roughly 4.5 W at 24 V, with an inrush current up to 6 A for 10 ms and a maximum dissipation of 2.8 W at 28.8 V. It connects ArmorPoint I/O modules to the EtherNet/IP network, serving as the remote communication interface for ArmorPoint I/O within automated control systems.
