Product Overview

The 1756-EN2TXT is an Allen-Bradley ControlLogix-XT chassis-mount EtherNet/IP communication module designed for extended temperature environments. It provides dual Ethernet RJ45 ports (10/100 Mbps), enabling up to 128 TCP and 256 CIP connections to the backplane and Ethernet. It installs in any slot of a ControlLogix-XT chassis and integrates into EtherNet/IP-based control systems, typically used in applications requiring industrial-grade communication under broader temperature ranges.

Best Suited For

  • ControlLogix-XT systems operating in harsh or extended-temperature environments
  • Dual-port EtherNet/IP network connectivity with redundancy or segmentation
  • Applications requiring high TCP and CIP connection counts (128 TCP, 256 CIP)
  • Deployment within chassis-based control systems requiring open-style communications modules
