I/O Modules with IP20 protection from Bihl+Wiedemann pay for themselves with 3 I/O stations or more

You too can profit by using the decentralised I/O Modules in IP20 from Bihl+Wiedemann. With just 3 or more I/O stations you save hardware costs and control cabinet space versus comparable approaches (Fig. 1). The I/O Modules (e.g. BWU2721 and BWU2723) also provide great flexibility in control cabinet installation and thereby reduce wiring complexity and expense (Fig. 2). 

Advantages of the IP20 I/O Modules from Bihl+Wiedemann


  • Reduced hardware costs (incl. connector construction): neither bus couplers nor fieldbus plugs (always one per station) are necessary; instead you need just oneGateway for the entire system (Fig. 1).



  • Save valuable control cabinet space: Bihl+Wiedemann modules combine up to 8 inputs and 8 outputs in a 22.5 mm wide housing (Fig. 1).

  • Reduced wiring complexity and expense: Bihl+Wiedemann modules can also be installed in the control cabinet right where the signals are actually needed (Fig. 2)
