Allen-Bradley 1756-EN2TXT ControlLogix XT EtherNet/IP Module
Product Overview
The Allen-Bradley 1756-EN2TXT is a high-performance EtherNet/IP communication interface belonging to the ControlLogix® XT (Extended Environment) series. This module is specifically engineered to bridge the gap between industrial control systems and enterprise-level Ethernet networks in extreme conditions where standard hardware would fail.
The "TXT" designation signifies that the 1756-EN2TXT is built with conformal coating and ruggedized internal components, enabling it to operate in temperatures as low as -40 °C and as high as +70 °C. It supports up to 128 TCP/IP connections and 256 Logix connections, facilitating high-speed messaging, distributed I/O control, and interlocking between multiple ControlLogix chassis. With its ability to handle deterministic data exchange via the Common Industrial Protocol (CIP), it remains a critical component for mission-critical infrastructure in harsh environments.
