The IZAR RDC PREMIUM is the most powerful Radio Data Concentrator of the Diehl Metering RDC product family. It enables wide area fixed networks for mass data transmission and network monitoring. With a maximum of 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 therefore to a more efficient process. A high interoperability is achieved by the conformity to Open Metering System Specifications (OMS-S).

  • Principle of operation

    The IZAR RDC PREMIUM receives radio telegrams according to EN13757 and the Open Metering System Specification (OMS-S) independent 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 and secure in flexibly settable intervals or time points to an (S)FTP server, where IZAR@NET or other systems can load the files for further processing. This happens automatically without the need to address each IZAR RDC PREMIUM individually.
