Data sheet:

Web-IO 2x Digital Input, 2x Digital Output

  • Web-IO 2x Digital Input, 2x Digital Output

Switch, monitor and count ...

With the Web-IO Digital you can control, acquire and monitor switching signals via TCP/IP Ethernet. Numerous Web and network services are available for reporting changes on the inputs and outputs. Remote control over the internet requires in the simplest case just a browser or smartphone.

Properties

Switching signals:

  • 2 switching inputs:
    • Digital 24V inputs
    • 32-bit pulse counter
  • 2 switching outputs:
    • Digital 24V outputs
      (12V, 48V, 110V, 230V via coupling relays)
    • Drive up to 500 mA
    • Short-circuit-protected

Connectivity:

  • Intuitive Web interface for simpler operation
    • Select between German or English
    • Switching the outputs directly from the Web interface
    • Adaptation for smartphone
  • Time-controlled switching
    • Switching times configured via online calendar
    • Switching times transferred as an iCal file (*.ics)
  • Box-to-Box
    • Pass switching signals over the network 1:1
  • Alarm and reporting functions:
    • Email for alarm sending or as status report
    • SNMP polling / alarm traps
    • Up to 4 alarm messages can be configured
  • Dynamic integration into other Web sites:
    • Direct access to current measurement values via AJAX, JavaScript and Java applet
  • Additional software interfaces for incorporating into your systems/databases:
    • OPC
    • Modbus TCP
    • Syslog
    • TCP and UDP sockets, client and server
    • FTP (data logging)
  • Internal clock
    • Time synchronization via time server calibration
    • Battery-backed device clock
  • Possible applications:
    • Remote monitoring and fault messaging
    • Cross-location switching
    • House and building automation
    • Process monitoring and visualization
    • Light, gate and cabinet control
    • Machine Data Collection (MDC)
    • More uses can be found here.

Power supply:

  • External
    • Screw terminal
    • 24 - 48V DC
  • Power-over-Ethernet (PoE)
    • Phantom power using data pairs
    • Power over unused wire pairs

Standards & more

  • Conforms to standards both in office and industrial environments:
    • High noise resistance for industrial environments
    • Low noise emission for residential and business areas
  • 5 year guarantee
