ADU500 - echipament autonom telemetrie

New product

ADU500 este un controller wireless (GSM) cu capabilitati de memorare si transmitere alerte prin SMS, avand un consum extrem de redus.

Este alimentat de o baterie Lithium Thionyl battery care ii permite functionarea autonoma pana la 10 ani .

Arhitectura cu dublu procesor; comunicatia este gestionata de un procesor separat, permitand reducerea sensibila a consumului in perioadele de standby.

  • 3 x intrari digitale;
  • 2 x intrari analogice;
  • 1 x intrare tip counter;
  • diverse variante de alimentare a senzorilor;
  • permite achizitia de pe max. 48 canale prin protocolul SDI-12
  • Compatibil MODBUS ASCII/485

Bateria se comanda separat.
