ALLEN BRADLEY 1734-AENTR Used Working Ethernet Adapter

Product Overview

The Allen-Bradley 1734-AENTR (Series B) is a high-performance POINT I/O EtherNet/IP Adapter featuring an integrated 2-port switch. This module serves as the communication interface for a distributed POINT I/O station, allowing for seamless connectivity to a ControlLogix or CompactLogix controller over an Ethernet network. As a Series B unit, it includes enhanced hardware stability and updated firmware capabilities over the original series. This Used Working adapter is a critical component for high-availability systems requiring "Device Level Ring" (DLR) topology to ensure network resilience.

Key Features

• Dual-Port EtherNet/IP: Features two RJ45 ports with an integrated switch, supporting Linear, Star, and Device Level Ring (DLR) network topologies.
• High Scalability: Capable of supporting up to 63 expansion POINT I/O modules on a single network node, providing a dense and flexible I/O solution.
• 10/100 Mbps Communication: Automatically negotiates network speed and duplex settings for optimized data throughput.
• DLR Compatibility: Provides hardware-level support for ring topologies, allowing the network to continue operating even if a single cable fault occurs.
• Simplified Configuration: Easily configured via RSLogix 5000 / Studio 5000 using standard Add-On Profiles (AOP).
• Diagnostic Indicators: Front-panel LEDs provide real-time status for Module Health, Network Status, Link Activity, and System Power.

Item Condition (Used Working)

• Functional Status: Used Working. The adapter has been professionally tested. Both Ethernet ports have been verified for link/activity, and the module successfully communicates with a Logix controller.
• Physical State: Clean industrial condition. The internal bus connectors are straight, and the locking mechanisms for DIN rail mounting are fully functional.
• Technical Integrity: Series B hardware. The firmware is in a stable, field-ready state. The rotary switches for IP address setting (or DHCP mode) are intact and move firmly.
• Note: Professional installation is recommended. This unit requires a 24V DC power source to provide the 5V DC fieldbus power for the connected I/O modules.
