Description
The Allen-Bradley 1756-EN2T is a high-performance EtherNet/IP communication module designed for the ControlLogix (CLX) family of programmable controllers. This module serves as a bridge between the ControlLogix backplane and an industrial Ethernet network, providing real-time I/O control and messaging capabilities. It supports 10/100 Mbps auto-negotiation, offers enhanced performance over legacy models like the 1756-ENBT, and is designed for demanding applications requiring high-speed data exchange. The 1756-EN2T features a single RJ45 port and is a standard choice for most ControlLogix systems. The listing also includes the 1756-EN2TR (dual-port with embedded switch for Device Level Ring networks), the 1756-ENBT (legacy 10/100M module), and the 1756-EWEB (web server module for remote monitoring), providing a comprehensive range of communication solutions.
