Allen-Bradley 1756-EN2TR ControlLogix Ethernet Bridge Module

Allen-Bradley 1756-EN2TR ControlLogix Ethernet Bridge Module is a dual-port EtherNet/IP communication module for Rockwell Automation’s ControlLogix backplanes, designed to bridge two Ethernet networks within a ControlLogix system. It provides two 10/100 Mbps Ethernet ports for EtherNet/IP traffic and supports up to 128 TCP connections, enabling robust data exchange between controllers and remote devices or I/O racks. The module is installed in any slot of a 1756 chassis, draws about 1 A from the 5 V backplane, and typically consumes around 5.1 W, with an operating temperature range of 0 to 60 C. Identified by 1756-EN2TR and Rockwell Catalog PN 73555 N19, this unit is used to extend Ethernet connectivity and bridge network segments in ControlLogix configurations, compatible with both ring and linear topologies and designed for reliable industrial performance.
