Product Overview
The Allen-Bradley 1761-NET-ENI is an Ethernet Interface Module designed to enable Ethernet communication for MicroLogix and other Allen-Bradley controllers that do not have built-in Ethernet capability. It acts as a bridge between serial-based PLCs and modern Ethernet networks, allowing remote access, monitoring, and data exchange over industrial Ethernet systems.
It is widely used to upgrade legacy MicroLogix systems so they can integrate into Ethernet/IP-based industrial automation networks.
