1756-EN2T ControlLogix EtherNet/IP Communication Module 100M | Allen-Bradley

The Original New Allen-Bradley 1756-EN2T ControlLogix EtherNet/IP Communication Module is a high-performance EtherNet/IP bridge module designed for demanding industrial automation applications. It provides high-speed data transfer between Logix 5000 controllers and remote I/O modules over EtherNet/IP networks. Operating similarly to the 1756-ENBT but with twice the processing capacity, the EN2T is engineered for applications requiring higher performance, increased connection capacity, and advanced network features.

Core Engineering Highlights:
10/100 Mbps EtherNet/IP communication | 256 Logix connections + 128 TCP/IP connections | 8-axis integrated motion over EtherNet/IP | 1A @ 5.1V DC / 3mA @ 24V DC | 5.1W power dissipation / 17.4 BTU/hr | Copper media with 1 Ethernet RJ45 + 1 USB port | Device Level Ring (DLR) & Parallel Redundancy Protocol (PRP) support | Web server for diagnostics | 0-60°C operating temperature (Series C chassis)
