Web-IO 4.0 Digital, 12xIn, 6xRelay Out

  • Web-IO 4.0 Digital, 12xInput, 6xRelay Output

Switch, monitor and count ...

With the Web-IO 4.0 Digital switching signals can be controlled, acquired and monitored over TCP/IP Ethernet. Numerous web and network services are available for reporting changes on the inputs and outputs - even directly in a browser. With 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.

Properties

Switching signals:

  • 12 switching inputs:
    • Digital 24V inputs
    • 32-bit pulse counter
  • 6 potential-free contacts
    • Switching voltage 12V, 24V, up to max. 48V
           (110V, 230V via coupling relays)
    • Switching current max. 5A

Connectivity:

  • Intuitive Web interface for simpler operation
    • Select between German or English
    • Switching the outputs directly from the Web interface
