Switching, monitoring and counting...

The Web-IO 4.0 Digital allows for the control, acquisition, and monitoring of switching signals via TCP/IP Ethernet. Its four switching channels can be configured as either inputs or outputs . Numerous web and network services are available for reporting changes to the inputs and outputs – even directly within a web browser. With protocols such as OPC UA , MQTT , and REST , the Web-IO is ideally suited for Industry 4.0 and the Internet of Things.

Switching signals:

• 4 channels:
  • Can be used as either input or output
  • 24V technology
  • Switching currents up to 500mA
  • 32-bit pulse counter
