The Allen-Bradley 1756-EN2TXT is an extended temperature EtherNet/IP communication module used in the ControlLogix-XT system from Rockwell Automation. It provides high-speed industrial Ethernet connectivity for ControlLogix controllers and is designed for harsh environmental conditions where wider operating temperature ranges are required.
This module is part of the XT (Extreme Environment) series, making it suitable for oil & gas, offshore, chemical plants, and other demanding industrial applications.
It supports standard EtherNet/IP communication for integration with PLCs, HMIs, SCADA systems, drives, and remote I/O.
