Allen-Bradley 1738-AENTR ArmorPoint Dual Port Adapter

The Allen-Bradley 1738-AENTR ArmorPoint Dual Port Adapter is a two-port EtherNet/IP ArmorPoint I/O adapter designed for on‑machine deployment, mounting on a DIN rail, and delivering two EtherNet/IP ports that can operate as an embedded switch to simplify daisy‑chain networking within ArmorPoint configurations. Power is supplied on the field side from 10 to 28 V DC, with a field‑side power requirement listed as 24 V DC (±4% ≈ 25 V DC) at 30 mA, and a reported power consumption of 4.5 W at 24 V, along with an inrush current rating of up to 6 A for 10 ms and a maximum power dissipation of 2.8 W at 28.8 V. The dual ports are implemented via M12 Quick‑Disconnect connectors and are configured as an embedded switch to ease expansion of EtherNet/IP networks without separate external switching hardware.
