Allen-Bradley 1734-AENTR EtherNet/IP Dual-Port Adapter – POINT I/O Series
Imagine a high-speed automotive assembly line grinding to a halt — not because of a mechanical failure, but because a single network adapter can no longer bridge the I/O subsystem to the control network. Without a reliable EtherNet/IP adapter at the heart of your POINT I/O rack, distributed I/O nodes go silent, PLCs lose real-time data, and production stops. The Allen-Bradley 1734-AENTR is engineered precisely to prevent this scenario, delivering deterministic, high-availability communication between your Logix controller and every I/O module on the rack.
Within the POINT I/O 1734 series — Rockwell Automation’s most widely deployed modular I/O platform — the 1734-AENTR occupies the premium tier. Its dual EtherNet/IP ports with integrated Device Level Ring (DLR) topology support set it apart from the single-port 1734-AENT, enabling sub-3 ms network recovery without a separate switch. Globally, the 1734 POINT I/O family is installed in tens of thousands of facilities across automotive, food & beverage, oil & gas, and semiconductor manufacturing, making the 1734-AENTR one of the most specified adapter modules in industrial automation procurement.

Industry & Equipment Applications
- Automotive Manufacturing: Body-in-white welding lines, paint shop conveyors, and end-of-line test stations requiring high-speed, fault-tolerant I/O.
- Food & Beverage: Hygienic packaging lines and CIP (Clean-in-Place) systems where wash-down environments demand robust, sealed panel designs.
- Oil & Gas / Petrochemical: ATEX Zone 2 certified installations in hazardous areas, including wellhead control panels and compressor skids.
- Semiconductor & Electronics: Precision process equipment requiring sub-millisecond I/O determinism and minimal network jitter.
- Water & Wastewater Treatment: Distributed pump station control with DLR ring topology for resilient remote I/O communication.
- Material Handling & Logistics: Sortation systems and automated storage/retrieval systems (AS/RS) with high I/O point counts.
System Integration & Compatible Parts
The 1734-AENTR is designed to work within the broader Allen-Bradley / Rockwell Automation ecosystem. Commonly paired components include:
- Controllers: ControlLogix (1756), CompactLogix (1769), GuardLogix — any Logix5000 platform with EtherNet/IP scanner capability.

Frequently Asked Questions
Q: What is the difference between the 1734-AENT and 1734-AENTR?
A: The 1734-AENTR features dual RJ-45 EtherNet/IP ports with an integrated DLR (Device Level Ring) switch, enabling ring topology without an external switch. The 1734-AENT has a single port and does not support DLR. For new installations requiring network redundancy, the 1734-AENTR is the recommended choice.
Q: How many I/O modules can one 1734-AENTR support?
A: A single 1734-AENTR adapter can support up to 63 POINT I/O modules on one rack/node, subject to the total power budget of the installed power supply.
Q: Is the 1734-AENTR compatible with ControlLogix and CompactLogix controllers?
A: Yes. The 1734-AENTR is compatible with any Logix5000-based controller (ControlLogix 1756, CompactLogix 1769, GuardLogix) that has an EtherNet/IP scanner port or EtherNet/IP communication module.
Q: What firmware version should I use?
A: Rockwell Automation periodically releases firmware updates for the 1734-AENTR. We recommend consulting the Rockwell Automation Product Compatibility and Download Center (PCDC) for the latest compatible firmware version relative to your controller’s Logix firmware revision.
Q: Do you supply new or refurbished units?
A: We supply both new OEM units and certified refurbished units. Please specify your preference when submitting your inquiry, and we will confirm availability and pricing for each option.
