Allen-Bradley 1768-ENBT Ethernet Interface Module

The Allen-Bradley 1768-ENBT is a single-port EtherNet/IP communication module designed for CompactLogix 1768 controllers, delivering a copper Ethernet interface for real-time industrial networking. It provides one RJ45 Ethernet port supporting 10/100 Mbps, enabling EtherNet/IP data exchange between the PLC backplane and external devices such as HMIs, SCADA systems, and other Ethernet/IP-enabled controllers. This module is mountable on a DIN rail or panel, and is intended for use with CompactLogix L4x controllers, connecting to the backplane to integrate control and networking in small-to-medium automation architectures. Cabling follows IEC 60603-7 for the RJ45 connector and requires Category 5e (or better) twisted-pair cable, with 2- or 4-pair configurations per the appropriate standard (TIA-568-B.1 or ISO/IEC 24702). Catalog Number 1768-ENBT and the part number PN-43849 identify this specific Ethernet interface module, which is commonly deployed to provide reliable Ethernet/IP communications for remote I/O access, PLC programming, status monitoring, and data exchange across an industrial network. In practice, the 1768-ENBT helps bridge a CompactLogix 1768 system to Ethernet networks, supporting standard EtherNet/IP communications without additional network adapters.
