Web-IO 12x Digital Input, 6x Digital Relay

  • Web-IO 12x Digital Input, 6x Digital Relay

Switch, monitor and count ...

With the Web-IO Digital you can control potential-free contacts via TCP/IP Ethernet and monitor switching signals. 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:

  • 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
    • 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
    • Configure up to 12 alarm messages
  • 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.
