Allen-Bradley 1756-EN2T EtherNet/IP Interface Module

The Allen-Bradley 1756-EN2T EtherNet/IP Interface Module is a two-port ControlLogix Ethernet/IP communications card that serves as the network interface between a Rockwell Automation controller and plant Ethernet devices. Designed as a one-slot, open-style module, it occupies a single backplane slot in a ControlLogix chassis and provides two RJ-45 copper Ethernet ports that support 10/100 Mbps EtherNet/IP communication. The EN2T supports up to 128 TCP connections over EtherNet/IP, enabling simultaneous data exchange with HMI systems, PLCs, and other CIP devices, while offering a continuous isolation rating of 30 V and an operating temperature range of 0 to 60 C (32–140 F). This module is used to connect and integrate Ethernet-based devices within a ControlLogix network, providing a standard path for data acquisition, monitoring, and remote I/O, and is part of Rockwell Automation's 1756 EtherNet/IP family. Configuration is performed throughRockwell Automation software in RSLogix 5000 or Studio 5000 environments, aligning with standard 1756 EtherNet/IP module setup.
