Switch remotely...

Using the Web-IO 4.0 230V Relay 4xNO, 4xCO you can control 230V switching signals via TCP/IP Ethernet. There are numerous Web and network services available for switching up to 6A with the eight integrated relays - even directly from the browser or from a smart phone. Using protocols such as MQTT and REST the Web-IO is an ideal fit in the world of Industry 4.0 and the Internet of Things.  

Switching signals:

• 8 switching outputs:
  • 4 x potential-free normally open contacts for 230V mains
  • 4 x potential-free changeover contacts for 230V mains
  • Switching currents up to max. 6A

Connectivity:

• Intuitive Web interface for simpler operation
  • Select between German or English
  • Switching the outputs directly from the Web interface
  • Adaptation for smartphone
  • HTTP and HTTPS
• Current Industry 4.0 protocols:
