The ZDUE-GPRS-PLUS-VI from Dr. Neuhaus Telekommunikation enables location-independent remote data readouts for energy, water or gas meters via the GPRS network.


This technology makes it inexpensive to read out meters at very short intervals, whereby the GPRS connection is set up in the same way as the previous AT connection via the GSM network. The data collected at short, regular intervals can be used to calculate trends and thus optimize load or network management.


Thanks to the integrated auxiliary voltage supply, the ZDUE-GPRS-PLUS-VI is also able to provide such battery-operated devices as quantity transformers with power.


Equipped with a compact enclosure according to DIN 43857-5, the ZDUE-GPRS-PLUS-VI is designed to be mounted on a meter board or on the meter terminal cover.
