Allen-Bradley 1756-EN2TRXT ControlLogix XT Dual-Port EtherNet/IP Module
Product Overview
The Allen-Bradley 1756-EN2TRXT is a high-performance communication interface designed for the ControlLogix® XT (Extended Environment) platform. Engineered to thrive in the most demanding industrial settings, this module bridges the gap between complex control logic and high-speed Ethernet networks.
Unlike standard communication cards, the 1756-EN2TRXT features a dual-port design with embedded switch technology. This allows for flexible network topologies, including star, linear, and—most critically—Device Level Ring (DLR) for enhanced network redundancy. With its "XT" designation, the module is equipped with conformal coating and ruggedized hardware to withstand corrosive atmospheres and extreme temperature fluctuations from -25 °C to +70 °C, ensuring continuous uptime in mission-critical applications.

Dual-Port Redundancy: The embedded switch technology enables Device Level Ring (DLR) functionality, providing a resilient network that can recover from a single point of failure within milliseconds.
-
XT-Ruggedized Performance: Specifically designed for "Extreme" environments, featuring conformal coating that shields sensitive electronics from humidity, dust, and sulfurous gases.
-
Integrated Motion on EtherNet/IP: Optimized for high-speed motion control, capable of managing up to 8 axes with deterministic precision.
-
Controller Redundancy: Fully compatible with ControlLogix redundancy systems, acting as the primary communication link for synchronized processor pairs.
-
High Connection Density: Efficiently manages 128 TCP/IP and 256 Logix connections, making it ideal for large-scale distributed I/O and SCADA integration.
