Datalogger IO-Expander

The I/O Expander takes as a central component of Immission measuring station the calculation of averages, controlling function controls and saving data. The raw data are analog, serial or read in via Ethernet. Automatically when certain events occur, a message by SMS or e-mail will be sent. The transmission of measurement data in the control center is via a modem or network. For configuration and visualization software IOVIS Lite is included. Furthermore, the stored values can requested with the integrated Web interface from any browser.

  • Acquisition of raw values and control of analyzers (analogue, serial, Ethernet)
  • Automatic and manual controlled calibration of analyzers
  • Generation of two different average values
  • Save data storage of calibration-, average values and messages
  • Data communication with central location (modem, LAN)
  • Automatic sending of event message (failure of analyzer, exceeding of limited values…) as SMS, e-mail or to the central location
  • Integrated web interface enables access to values of station
  • Hardware without moving parts (passive cooling)
  • Configurations- and visualization software IOVIS lite saved on the integrated Samba server
