WAGO 750-343

WAGO 750-343 – Fieldbus Coupler PROFIBUS DP ECO

Overview

The WAGO 750-343 is an ECO class PROFIBUS DP fieldbus coupler, designed to connect PROFIBUS DP networks to WAGO’s modular I/O System 750. This coupler automatically detects attached I/O modules and builds the process image. It supports baud rates from 9.6 kBaud up through 12 MBaud. Ideal for mixed analog and digital I/O deployments in industrial automation systems.

Key Features

• PROFIBUS DP communication, 9.6 kBaud up to 12 MBaud

• Automatic recognition of module structure on the internal bus

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

• Handles large I/O point counts (approx. 6000 I/O points with repeaters)

• Uses D-Sub 9-pin connector for the PROFIBUS interface

• Rotary DIP switches for setting node address

• LEDs for status indication: RUN, BF (Bus Fault), BUS, I/O, diagnostics

• System supply via 24 VDC; fieldbus and internal electronics isolated from load side
