Allen-Bradley 1756-EN3TR Ethernet Motion Module

The Allen-Bradley 1756-EN3TR Ethernet/IP motion module is a dual-port EtherNet/IP interface for ControlLogix systems, enabling CIP Motion communication over Ethernet. It occupies a single slot in a standard 1756 chassis and is powered from the backplane, offering two copper 10/100 Mbps Ethernet ports to connect the controller to motion devices and networks. The EN3TR supports up to 128 TCP connections and up to 128 motion axes, enabling scalable, multi-axis coordination across EtherNet/IP networks for servo drives and other CIP-motion-capable devices within the Rockwell Automation ControlLogix ecosystem. Designed for industrial automation environments, it delivers high-throughput, deterministic motion data exchange between the ControlLogix controller and distributed motion resources, aligning with Rockwell’s CIP Motion standards.
