ALLEN-BRADLEY 1794-AENTRXT | FLEX XT EtherNet/IP Adapter

📌 Product Description

The ALLEN-BRADLEY 1794-AENTRXT is a FLEX I/O XT Dual-Port EtherNet/IP Adapter Module from Rockwell Automation. It provides the network interface between a FLEX I/O XT system and an EtherNet/IP control network, supporting communication with compatible industrial controllers and allowing distributed I/O modules to be integrated into the automation system.

The adapter supports up to 8 FLEX I/O modules and provides two RJ45 Ethernet ports for network connectivity. Communication operates at 10/100 Mbps, while the module uses a nominal 24 VDC supply with an operating range of 19.2–31.2 VDC.

As a FLEX I/O XT device, the 1794-AENTRXT is intended for applications requiring an extended operating temperature range. Published specifications identify an operating range of approximately -20°C to +70°C, making it suitable for industrial installations with wider ambient temperature requirements.
