The IZAR Radio Data Concentrator STANDARD is a Smart Metering transceiver of the Diehl Metering RDC product family, based on the Open Metering System Specification (OMS-S). Interoperability, data logging and remote configuration makes it a core product for future full-coverage Smart Metering roll-outs with a multi-utility approach. IZAR RDC STANDARD is designed for implementing a radio fixed network with excellent cost-effectiveness and technical specification.

  • Principle of operation

    The IZAR RDC STANDARD receives radio telegrams according to EN13757 and the Open Metering System Specification (OMS-S) independent of the measured medium. These are saved at a set logging interval using an optional device list or 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 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 STANDARD individually. A subsequent individual or higher-level configuration or a firmware update is also controlled via the central FTP server.
