Allen-Bradley 1756-EN2TR ControlLogix EtherNet/IP Interface Module

Description

The Allen-Bradley 1756-EN2TR is a dual-port EtherNet/IP interface module belonging to the ControlLogix communication module series, designed for industrial automation network integration. It supports 10-100 Mbps EtherNet/IP communication rates, with connectivity for up to 256 Logix connections and 128 TCP/IP communication connections, enabling robust data exchange across multiple devices. The module offers integrated motion control capabilities, supporting up to 8 axes for EtherNet/IP network-based motion applications.

Equipped with two Ethernet RJ45 Category 5 ports and one USB 1.1 full-speed (12 Mbps) port, it supports both linear topology and Device Level Ring (DLR) topology for flexible network configuration. It can be installed in any slot of a ControlLogix chassis, and connects via unshielded or shielded RJ45, Category 5 twisted pair cables.

Key functional features include support for general messaging, real-time I/O messaging, real-time control, and time synchronization, while also enabling simultaneous transmission of safety, control, and diagnostic data in compliance with CIP safety standards. Its power specifications include a current draw of 1A at 1.5V DC, maximum power consumption of 5.1W, and heat dissipation of 17.4 BTU per hour, making it suitable for demanding industrial control environments.
