The M-BUS RECEIVER is used for stationary reading of IZAR RADIO consumption meters. Remote reading and data logging of these meters will be done in combination with an IZAR CENTER M-Bus master.

  • Radio receiver for capturing IZAR RADIO data telegrams
  • Available in 868 MHz and 434 MHz version
  • No M-Bus cabling from consumption meter to M-Bus master necessary
  • Two-wire M-Bus interface for direct connection to an IZAR CENTER communication central
  • Powered through M-Bus interface, no external power supply necessary
  • IZAR RADIO meters and standard M-Bus meters may be used simultaneously in one system
  • Internal memory for buffering the last received radio telegram from up to 500 consumption meters

Principle of operation

The M-BUS RECEIVER receives radio telegrams from IZAR RADIO meters and is storing them into its internal memory. Each time a new radio telegram is received, the M-BUS RECEIVER is deleting the old one from that meter. The M-BUS RECEIVER can only be used in combination with an IZAR CENTER M-Bus master. Here it is possible to do an interval reading of the M-BUS RECEIVER like it is done with a normal M-Bus meter. The data stored in the IZAR CENTER memory can be transferred to the IZAR@NET software.
