Potential-free switching

With the Web-IO 4.0 up to four relay outputs can be controlled via TCP/IP Ethernet. Three of the outputs can operate as potential-free normally open (NO). An additional output works as a potential-free changeover contact (CO). Numerous web and network services are available to control the switching outputs and to report or log changes - also directly in the browser. Using protocols such as OPC UA, MQTT and REST the Web-IO is an ideal fit in the world of Industry 4.0 and the Internet of Things.

Switching signals:

• 4 switching outputs
  • 3x potential-free contacts as normally open (NO)
  • 1x potential-free contacts as changeover contact (CO)
  • Switching voltage up to 48V
         (110V, 230V via coupling relay )
  • Switching current max. 2A at 24V, 0.5A at 48V

Connectivity:

• Intuitive web interface for easier operation
  • German or English switchable
  • Switching outputs directly from the web interface
  • Adapted display for smartphones
  • HTTP and HTTPS
• Current Industry 4.0 protocols:
  • OPC UA , REST and MQTT support
  • AMQP on request
• Box-to-Box
  • Forward switching signals 1:1 over the network
• Alarm and reporting functions:
  • Email for alarm or status report
  • SNMP queries/alarm traps V1 V2 V3
  • Switching your own outputs in case of alarm
  • Switching the outputs of another Web-IO
  • HTTP requests to control third-party devices
  • Up to 30 actions can be configured
• Dynamic integration into other websites:
  • Direct access to current IO states via HTTP requests , AJAX and JavaScript
• Additional software interfaces for integration into your systems/databases:
