1756-EN3TR

Operating Temperature Range: 0 °C to +60 °C for continuous operation; storage temperature ranges from -40 °C to +85 °C, relative humidity 5 %-95 % non-condensing, open-style enclosure with IP20 rating.
Power Supply: Powered entirely by ControlLogix chassis backplane, draws 1 A at 5.1 VDC and 3 mA at 24 VDC, maximum power consumption 5.1 W. Basic insulation isolation between Ethernet interface and system backplane, test voltage reaches 980 V AC for 60 secondsRockwell A….
Input Specification: Two RJ45 10/100 Mbps twisted-pair Ethernet ports accept incoming EtherNet/IP network signals; one USB 2.0 mini-B port serves as local configuration input for parameter upload and diagnostic access. It receives backplane data packets from ControlLogix CPU over chassis internal bus. No hard-wired digital or analog field input terminals are equipped on this module.
Output Specification: Two RJ45 Ethernet ports output EtherNet/IP protocol messages to remote I/O, servo drives and upper-level host systems. It transmits controller logic data, motion commands and alarm information from local chassis to network nodes, and forwards field device feedback data back to ControlLogix CPU via backplane bus. Front-panel LED lamps output visual status indication for module health, link activity and network fault conditions.
Main Characteristics & Function: It supports up to 128 TCP connections, 256 Logix CIP connections and maximum 128 CIP motion axes for high-density multi-axis motion control scenarios. Embedded switch hardware realizes DLR ring network function to reduce network downtime caused by single cable failure. It handles implicit real-time I/O messages for field devices and explicit message communication for configuration and data acquisition. Hot-swap capability allows module replacement during system running. Built-in self-diagnosis detects communication failures and hardware abnormalities, and reports fault status to ControlLogix controller. This single-slot module can be inserted into any vacant slot of 1756 series chassis, cooperating with ControlLogix CPU to accomplish industrial network interconnection, real-time I/O exchange and synchronized multi-axis motion control tasks.
