The 1734-AENTR is a premier POINT I/O Dual Port Network Adapter designed to provide reliable and efficient EtherNet/IP connectivity for distributed I/O systems. Featuring a built-in dual-port switch, this module seamlessly supports Device Level Ring (DLR) topologies to ensure uninterrupted data transmission and maximum network uptime for critical industrial automation processes.
Built-in power supply powers the I/O modules through the backplane
Up to 63 I/O modules per assembly, for up to 504 points on a single network node
Provide the interface between the POINT I/O modules and backplane, and the desired network
To ensure maximum system availability and network uptime for critical industrial processes, the 1734-AENTR features an integrated dual-port Ethernet switch that fully supports high-speed 10/100 Mbits/s communication rates in both half and full-duplex modes, enabling native deployment within fault-tolerant Device Level Ring (DLR) as well as linear and star network topologies.
The module incorporates a built-in power supply that delivers system-side power to all connected I/O modules directly through the backplane, eliminating the need for redundant power wiring. A single 1734-AENTR network node delivers high-density scalability and cost-efficiency with remarkable extension capabilities, supporting up to 63 POINT I/O modules per assembly to accommodate up to 504 discrete or analog channels on a single IP address. Housed in a compact, open-enclosure rating architecture that conserves control cabinet space, the device features a ruggedized mechanical structure that snaps directly onto standard 35 mm DIN rails for rapid, tool-free installation and commissioning, functioning as an ideal distributed I/O solution for complex, high-velocity automation environments.

Automotive Manufacturing
Aggregates real-time sensor feedback and actuator commands from proximity switches and pneumatic valves on robotic cells, routing data over Device Level Ring (DLR) to ensure continuous operation.
Food and Beverage Processing
Connects digital inputs from bottle-presence photoelectric sensors and digital outputs to high-speed filling valves, maximizing space within washdown-rated terminal boxes.
Pharmaceutical and Life Sciences
Collects critical ambient temperature, humidity, and pressure data via high-density analog input modules on a single network node to assist in regulatory compliance.
Semiconductor and Electronics Assembly
Fits into compact, space-constrained control cabinets on the machine chassis to manage micro-sensors and precision vacuum actuators with minimal wiring.
Oil and Gas
Gathers operational status data from pressure transmitters and valve positioners inside remote control rooms, utilizing EtherNet/IP for reliable upstream telemetry.
Pulp and Paper Mills
Handles decentralized analog I/O for moisture, tension, and steam pressure control loops while tolerating high humidity and ambient temperatures within distributed cabinets.
When operating the 1734-AENTR module, ensure that the external 24V DC input power supply has the correct polarity and sufficient capacity to prevent system overload, avoiding connections that exceed 63 modules or the 1.0A backplane current limit. Given its open enclosure rating, this device must reside inside a dust-free, moisture-proof industrial control cabinet and latch securely onto a properly grounded 35 mm DIN rail.
For network configuration, assign a unique IP address via the hardware rotary switches or network software, and route Ethernet cables away from high-voltage lines to eliminate electromagnetic interference. During Device Level Ring (DLR) cabling, verify that the master controller actively runs the ring supervisor feature to ensure network redundancy operates correctly.
The Allen Bradley 1734-AENTR is a high-performance POINT I/O EtherNet/IP adapter module designed to seamlessly bridge I/O data over industrial networks. Operating on a 24V DC input voltage, this open-enclosure module features a built-in dual-port switch supporting 10/100 Mbps communication rates in both half and full-duplex modes. It provides reliable, high-speed connectivity and flexible network topologies for compact, distributed automation systems.
It is a dual-port EtherNet/IP adapter module from the POINT I/O series, used to connect distributed I/O modules to an industrial Ethernet network.
What is the primary function of the 1734-AENTR?
It acts as a communication bridge between the control system (such as ControlLogix or CompactLogix controllers) and local POINT I/O modules, enabling high-speed data transmission.
What ethernet communication rates does the 1734-AENTR support?
It supports 10/100 Mbits/s communication rates with auto-negotiation for half-duplex or full-duplex modes.
What is the enclosure rating of the 1734-AENTR?
It has an Open Enclosure rating, which means it must be installed inside a dust-free and moisture-proof industrial control cabinet.
How do you set the IP address of the 1734-AENTR?
It can be set using the three hardware rotary switches on top of the module (to define the last octet between 001 and 254) or through BOOTP/DHCP software over the network.
