WAGO 750-377

WAGO 750-377 – Fieldbus Coupler PROFINET IO (3rd Generation ECO Advanced)

Overview

The WAGO 750-377 is a 3rd-generation fieldbus coupler in the ECO Advanced line. It links PROFINET IO real-time Ethernet networks to the WAGO I/O System 750. It has dual RJ-45 ports with integrated Ethernet switching, supports mixed analog and digital modules, and can handle up to 64 I/O modules per node. Designed for reliable I/O process image exchange, industrial robustness, and efficient operation.

Key Features

• PROFINET IO communication protocol

• Dual Ethernet (RJ-45) ports with built-in switch for line topology

• Mixed arrangement support (analog modules + digital modules)

• Device name configurable via DIP switch or PROFINET DCP

• Support for PROFIsafe V2 and PROFIenergy profile V1.0

• Good efficiency and isolation performance

• Diagnostics and standard status LEDs
