Information About 1756-EN2TR

The 1756-EN2TR is part of the ControlLogix communication module series, designed to provide high-speed Ethernet/IP connectivity with redundancy for enhanced network reliability. It supports real-time I/O messaging, controller-to-controller communication, safety data transfer, and integrated motion with up to 8 axes on Ethernet/IP. This module operates at 10/100 Mbps with auto-negotiation and supports up to 256 Logix connections and 128 TCP/IP connections, enabling scalable integration in complex automation systems. It consumes 1 A at 5 VDC from the chassis backplane with a power dissipation of 5.1 W and thermal dissipation of 21.28 BTU/hr. Featuring Device Level Ring (DLR) and Parallel Redundancy Protocol (PRP) support, the 1756-EN2TR improves network resiliency while maintaining seamless communication. Its open-style design, single-slot width, and compatibility with any slot in the ControlLogix chassis provide flexible installation in industrial environments.
