Allen-Bradley 1756-EN4TR EtherNet/IP Communication Module

High-capacity ControlLogix communication with dual gigabit Ethernet ports, resilient network topology support and CIP Security capability.

Product Overview

The Allen-Bradley 1756-EN4TR is a ControlLogix EtherNet/IP communication module for high-capacity industrial network integration. Rockwell Automation specifies two RJ45 ports supporting 10/100 Mbps and 1 Gbps operation, 512 TCP connections, 1000 I/O connections and 528 messaging connections. The module supports Device Level Ring, linear and qualified Parallel Redundancy Protocol topologies, redundant adapter applications, CIP Security and up to 256 integrated motion axes. It occupies one ControlLogix chassis slot and can be installed in any slot. Before replacement, verify the complete catalog number, Series, firmware, chassis, controller project, network topology, security policy and redundancy requirements.
