Allen Bradley 1794-AENTRXT Flex I/O Dual Port Ethernet/IP Adapter Module

Product Introduction

The Allen-Bradley 1794-AENTRXT FLEX I/O Dual Port EtherNet/IP Adapter Module is an extended temperature communication interface designed to connect FLEX I/O systems to EtherNet/IP networks in demanding industrial environments. It combines high-speed Ethernet communication with enhanced environmental tolerance, making it suitable for applications exposed to temperature extremes.

Featuring dual Ethernet ports, the module supports Device Level Ring (DLR) topology, enabling network redundancy and continuous communication even in the event of a network interruption. This ensures high system availability, which is critical for process continuity and operational reliability.

The 1794-AENTRXT operates on a 24V DC power supply and is designed with an open-style structure for easy integration into control cabinets. Its DIN rail mounting capability and compact size make it ideal for distributed I/O installations where flexibility, durability, and stable communication are required.
