Allen-Bradley 1756-EN3TR is a high-capacity ControlLogix EtherNet/IP communication module used to connect a ControlLogix chassis to industrial Ethernet networks. Its dual-port architecture supports linear and ring topologies while providing the connection capacity needed for large I/O systems, HMIs, peer controllers, drives, and integrated motion applications.
This page is for the exact manufacturer reference 1756-EN3TR. Corwin Solutions creates exact model-level listings because industrial hardware within the same family can look almost identical while differing in network protocol, electrical rating, firmware, memory, safety function, mechanical fit, accessories, or lifecycle status.
Key product details
Common applications Common applications include large ControlLogix remote-I/O networks, integrated motion systems, drive networks, production lines, process systems, redundant architectures, HMIs, data collection, and machine cells with substantial EtherNet/IP traffic.
Compatibility and ordering note: Confirm the exact 1756-EN3TR catalog number and series, controller and chassis firmware, EtherNet/IP topology, DLR or redundancy use, connection count, motion-axis requirements, IP addressing, produced/consumed tags, module firmware, AOP, and existing network configuration before replacement. Similar 1756 Ethernet modules can differ substantially in speed and connection capacity.
Why this part is commonly sourced: Buyers and maintenance teams may need the exact model to restore a failed production asset, preserve an installed OEM platform, build strategic spare inventory, support an obsolete machine, complete a BOM, or avoid unnecessary redesign and commissioning during a time-sensitive repair.
Need 1756-EN3TR? Send Corwin Solutions the required quantity, preferred condition, ship-to destination, and delivery deadline. For replacement requests, include a clear photo of the existing nameplate plus any known series, firmware, network, motor, HMI project, terminal, safety, or option information. Availability, condition, exact configuration, lifecycle context, and lead time are confirmed at quotation.
