SKU MX-7.5366112.
About the product

The MX-7 data logger allows reading of Modbus and M-Bus devices, and send the data to remote users / server through Modbus GPRS modem or Ethernet. It also provides SMS sending services for alarm events. Data logger can read Kamstrup, Sensus, DIEHL, Danfoss, Itron, Landis & Gyr and other meters (like exotic meters / industrial meters). This universal Data logger MX-7 can be used not only for commercial metering, but also for industrial metering and for business center, shopping mals or public institution building management.

Device has analog inputs (current, voltage, R or PT100 temperatures sensors), digital inputs (logging of alarms and events, limit switches, push buttons...) and digital outputs (for remote management). The stored data can be consulted remotely using standard open Modbus TCP/IP protocol, making greatly easy the integration of several signals and systems into your management software.
