Remote Monitoring Unit

The Remote Monitoring Unit (RMU) is a GSM/3G-based data acquisition and control unit capable of reading voltage/current values, discrete digital inputs and controlling discrete digital input & outputs.

With the integration of the Remote Monitoring Unit into the electrical line feeds, the user should be able to remotely take accurate readings of the Voltage and Current parameters as and when required. Additionally, the RMU have the provision for defining upper and/or lower voltage/current thresholds for SMS Alerts. The unit shall be scalable in terms of the number of inputs & outputs. Additionally, the unit has a 230V AC switching Relay to control other devices. The unit will have a power supply of its own and should consume no more than 50Watts.
