WAGO 750-370

WAGO 750-370 – Fieldbus Coupler PROFINET IO (2nd Gen)

Overview

The WAGO 750-370 is a 2nd-generation PROFINET IO fieldbus coupler for WAGO’s I/O System 750. It connects via two RJ-45 Ethernet ports with an integrated 2-port switch. It supports mixed digital, analog, and specialty I/O modules. The coupler automatically configures, includes diagnostics and LEDs for status, and handles substantial process images for both inputs and outputs.

Key Features

• PROFINET IO protocol, Ethernet 100Base-TX (100 Mbit/s)

• Two-port RJ-45 switch built in

• Supports up to 64 I/O modules per node

• Large process image: up to 320 bytes input / 320 bytes output

• Device name assignment via LLDP or DIP-switch fallback

• Power supplied via 24 VDC field-side and system supply contacts

• Status LEDs for Link / Activity, Bus Fault, Diagnostic, I/O, and supply voltage

• 10 A field-power jumper capacity

• Isolation 500 V between system/supply sides
