WAGO 750-352

WAGO 750-352/040-000 – Ethernet Coupler Extreme (3rd Generation)

Overview

The WAGO 750-352/040-000 is a rugged “Extreme” version of the Ethernet fieldbus coupler in the WAGO I/O System 750/753. It supports robust communication over Ethernet using Ethernet/IP and Modbus TCP/UDP protocols. It includes two RJ-45 ports with an integrated switch, supports standard Ethernet services (HTTP, DHCP, DNS, SNMP, etc.), and features a web server for configuration and status monitoring. Built for harsh environments, it delivers reliable performance under temperature extremes, vibrations, and electrical stresses. 

Key Features

• Supports Ethernet/IP and Modbus TCP/UDP protocols

• Dual RJ-45 Ethernet ports with built-in switch and Auto-MDI(X) / Auto-Negotiation

• Integrated web server for configuration & status feedback

• Network services support: HTTP, BootP, DHCP, DNS, SNMP, FTP

• IP-rated protection and Extreme-class robustness for tough ambient conditions

• LED indicators for network status, power, diagnostics

• Designed for DIN-rail mounting and modular I/O expansion
