1794-AENTRXT | Allen-Bradley Flex I/O Dual Port Ethernet Adapter - Petro Auto Tech

Product Overview

The 1794-AENTRXT is a Flex I/O dual port Ethernet adapter from Allen-Bradley, part of the Rockwell Automation Flex I/O 1794 series. This adapter enables redundant Ethernet/IP control systems to communicate with Flex I/O devices. It mounts on a DIN Rail and requires no network scheduling or routing tables. Designed for extended temperature ranges, it supports up to 8 I/O modules.

Technical Specifications Analysis

The 1794-AENTRXT operates with an input voltage of 19.2 to 31.2 Volts DC. It features two Ethernet ports with a data rate of 10/100 Mbps. The unit weighs 0.56 lbs (0.26 kg) and has an open enclosure. Conformal coating protects against harsh environments. These specs ensure reliable performance in demanding industrial settings.

Application Scenarios & Usage Methods

Use the 1794-AENTRXT in redundant Ethernet/IP control systems for critical processes like oil and gas, water treatment, or manufacturing. Connect up to 8 I/O modules to monitor sensors and actuators. The dual port design allows for network redundancy, minimizing downtime. Mount the adapter on a DIN Rail and connect using Category 5 Ethernet cables.

Installation Guide & Packing List

Install the 1794-AENTRXT on a zinc-plated yellow-chromate steel DIN Rail for proper grounding. Power the module from a SELV or PELV-compliant supply. Do not replace or remove the module while power is applied to avoid unintentional machine motion. The package includes the 1794-AENTRXT adapter module only. Additional mounting hardware and cables are sold separately.

Purchasing Advice

When buying the 1794-AENTRXT, verify your system requires a dual port Ethernet adapter with conformal coating for extended temperature ranges. This model supports 8 I/O modules and redundant control. Petro Auto Tech stocks genuine Allen-Bradley parts with fast shipping. Confirm your input voltage matches 19.2 to 31.2 Volts DC.

Repair & Maintenance Tips

To maintain the 1794-AENTRXT, keep the enclosure clean and free of dust. Use static-safe procedures when handling the module. Check Ethernet cable connections periodically for secure fit. Store the adapter in static-safe packaging when not in use. Avoid touching connectors and components directly.
