MX-3 GSM/GPRS Modbus Data Logger Data Communication

MX-3 data logger is dedicated for real time logging and analyzing of data. Using GPRS/GSM, logger sends data to re- moteusers/server.MX-3 can also communicate with other controllers and sensors.Device has wide range of optional interfaces and protocols and can read any kind of meters, controllers and sensors equipped with standard protocols. Perfect for telemetry/monitoring, control and smart metering.


  • Reading data from meters (heat, water, gas, electricity...),  sensors and controllers
  • Independent data log with real time stamp (Real Time Clock)
  • Supported interfaces: M-Bus, GSM/GPRS, RS232,RS485,Data/Req
  • Up to 3 analog inputs (current, voltage, PT100 orPT1000)
  • Up to 4 discrete inputs (contact, impulse counter, alarm)
  • Remote communication and updates through GSM/GPRS
  • Galvanically isolated interfaces and power supply
  • SMS sending for alarm events
  • Batteries management. The remote monitoring devices can charge the battery and use it to power supply in the event of blackout
  • Supported protocols: Modbus RTU, Modbus TCP/IP, FTP server/cli-ent, IEC60870-5-104:2000 and others

MX-3 data logger / gateway is suitable for data acquisition from any kind of meters using standard protocols. Our R&D department also can adjust our device to read meters via non-standard protocols.

MX-3 can read Kamstrup,  Sensus, Diehl, Danfoss,  Itron, Landis & Gyr,  Apator and other meters (like exotic meters, in- dustrial meters).

MX-3 can also work as controller/controll unit and even control /read other controllers, like Danfoss ECL 300.
