Specification

SEODescription

The 1761-NET-ENI module is an Ethernet interface designed to enable seamless communication between Allen-Bradley PLCs and Ethernet-based networks. As a compact communication module, it bridges legacy serial devices (DF1 or DH-485 protocols) to Ethernet/IP, supporting real-time data exchange. The 1761-NET-ENI ethernet interface features a single RJ45 Ethernet port and a serial port, operating at 10/100 Mbps with 24V DC power input and an industrial temperature range of 0–60°C. Widely used in manufacturing, automation, and process control, it simplifies integration of older equipment into modern systems. Key advantages include plug-and-play setup and remote monitoring capabilities, though its dependency on specific PLC models and limited protocol flexibility may require additional configuration for complex networks. The 1761-NET-ENI communication module ensures reliable connectivity while maintaining backward compatibility.
