WAGO 750-333

WAGO 750-333 – Fieldbus Coupler PROFIBUS DP (2nd Generation)

Overview

The WAGO 750-333 is a 2nd generation fieldbus coupler enabling PROFIBUS DP communication at up to 12 MBaud. It links the modular WAGO I/O System 750 to a PROFIBUS master, automatically detecting attached modules to build the process image. Designed for flexible, reliable industrial signal processing in PROFIBUS DP setups, it supports digital and analog I/O modules with strong power and isolation specs.

Key Features

• PROFIBUS DP / DP-V1 communication at 12 MBaud

• Automatically identifies and maps connected I/O modules to build input/output process image

• Support for up to 63 I/O modules per node

• Large process image size: 244-byte inputs + 244-byte outputs

• Rotary switches for station (node) address configuration

• LED indicators for status (RUN, BF, I/O, power, fault)

• Robust power jumper contacts supplying field power

• Isolation between system and fieldbus supply

• Rugged design with IP20 protection
