Designed for industrial automation, this module supports 10\/100 Mbps transmission rates, 128 TCP\/IP connections, and up to 8 axes for integrated motion. The 1756-EN2TR eliminates single points of failure by enabling ring and star topologies, boosting overall system availability and reducing costly downtime.\u003c\/p\u003e\u003ch2\u003eKey Specifications\u003c\/h2\u003e\u003cp\u003eBased on available data, the Allen-Bradley 1756-EN2TR features dual RJ45 ports for redundant Ethernet networks and a USB 1.1 port. It draws 1 amp at 5 volts backplane current and 3 milliamps at 24 volts. Power consumption is 5.1 watts, with thermal dissipation of 21.28 BTU per hour. The module operates in temperatures from 0 to 60 degrees Celsius and fits in any ControlLogix chassis slot. For exact parameters, please contact UBEST Automation for the complete datasheet.\u003c\/p\u003e\u003ch2\u003eIndustry Applications\u003c\/h2\u003e\u003cp\u003eThe Allen-Bradley 1756-EN2TR excels in manufacturing plants requiring high-availability control networks. For example, in a packaging line, the dual-port module ensures continuous I\/O communication even if one network path fails. In material handling systems, the 1756-EN2TR supports real-time messaging and distributed I\/O, reducing latency and improving throughput. Its support for CIP Safety allows simultaneous transfer of safety and control data, making it ideal for robotic workcells.\u003c\/p\u003e\u003ch2\u003eInstallation \u0026amp; Setup Guidance\u003c\/h2\u003e\u003cp\u003eInstalling the Allen-Bradley 1756-EN2TR is straightforward. Insert the module into any available slot in a ControlLogix chassis. Use Category 5 or 6 twisted-pair cables for the RJ45 connections. Configure the IP address via the BOOTP-DHCP tool from Rockwell Automation. Ensure the subnet mask and gateway are set correctly for network communication. No additional routing tables are required—the 1756-EN2TR manages messaging encapsulated in TCP\/IP automatically.\u003c\/p\u003e\u003ch2\u003eCompatibility \u0026amp; Integration\u003c\/h2\u003e\u003cp\u003eThe 1756-EN2TR integrates seamlessly with other Allen-Bradley controllers such as CompactLogix, SLC 500, PLC-5, and MicroLogix. It also communicates with HMI and SCADA systems, including third-party devices through qualified partners. The module supports Device Level Ring (DLR) and parallel redundancy protocol (PRP) for enhanced network resilience. It works with Flex I\/O and POINT I\/O redundant Ethernet adapters, expanding your system's capabilities without requiring expensive communication adapters.\u003c\/p\u003e\u003ch2\u003eSelection Guide \u0026amp; Purchasing Advice\u003c\/h2\u003e\u003cp\u003eBefore purchasing the Allen-Bradley 1756-EN2TR, verify your ControlLogix chassis model and backplane power capacity. The module requires 1 amp at 5V and 3 mA at 24V. Ensure your network infrastructure supports 10\/100 Mbps auto-negotiation. For new installations, consider ordering spare modules to minimize downtime.
