Allen-Bradley 1756-EN2TR EtherNet IP Communications Module

The Allen-Bradley 1756-EN2TR EtherNet/IP Communications Module is a dual-port Ethernet/IP interface for ControlLogix systems, delivering two 10/100 Mbps RJ-45 ports to connect EtherNet/IP devices across a backplane rack. Designed for chassis mounting in any slot, it draws 1.2 A from the 5 V backplane and 3 mA from the 24 V backplane, with a measured power consumption of 5.1 W and a continuous insulation voltage of 30 V. The module supports up to 128 TCP connections and operates in ambient temperatures from 0 to 60 C (32 to 140 F). As part of the 1756 ControlLogix family, it enables Ethernet/IP communications between the controller and remote I/O, HMIs, and other Ethernet/IP-capable devices.
