IZAR RDC PREMIUM is the most powerful Radio Data Concentrator of the Diehl Metering product family. It makes wide area fixed networks ready for mass data transmission and network monitoring. With two high-performance radio receivers, state of the art embedded technology and an industrial design, made for harsh outdoor conditions, it contributes significantly to a reduction of concentrator locations and so to a more efficient process. A high interoperability is achieved by the conformity to Open Metering System specifications (OMS).

  • Principle of operation

    IZAR RDC PREMIUM receives radio telegrams according to EN13757 and the Open Metering System specification (OMS) regardless of the measured medium. These are saved on the basis of a filter function (e.g. according to medium or manufacturer). The collected and processed data are exported fully automatic at flexible setting intervals or time points to a (S)FTP server, where IZAR@NET 2 or other systems can load the files for further processing.
