Allen-Bradley 1756-ENBT EtherNet/IP Network Interface Module

The Allen-Bradley 1756-ENBT EtherNet/IP Network Interface Module enables Ethernet connectivity between ControlLogix controllers and distributed devices in industrial automation systems. Mounted in a ControlLogix chassis, it serves as a bridge between the backplane and the Ethernet network, enabling communications with HMIs, remote I/O, drives, and other PLCs over EtherNet/IP. Key specifications include 1 × Ethernet (RJ-45) port at 10/100 Mbps, up to 64 TCP connections and 128 CIP connections, with power requirements of 700 mA at 5.1 V DC (and 3 mA at 24 V DC) and ~3.7 W dissipation, and an operating temperature range of 0 to 60°C. It is compatible with ControlLogix chassis and Logix controllers, with common replacements including 1756-EN2T, 1756-EN2TR, and 1756-EN3TR.
