GSM remote monitoring and remote control refers to the measurement of disparate devices from a control room and the ability to change the operation of these devices from that central office.
Witura remote telemetry unit RTU monitors the field digital and analog parameters and transmits all the data to the Central Monitoring Station via Witura remote monitoring software. In some control applications, This GSM switch drive high current capacity relays to a digital output or DO board to switch power on and off to devices in the field. This GSM telemetry system also can monitor analog inputs of different types including 4 to 20 milliamperes 4-20 mA, 0 to 10 V., -2.5V to 2.5V, 1 to 5V etc.; the GSM GPRS controller then translates this raw data into the appropriate units such as gallons of water left or temperature and presenting the data to the user mobile phone via SMS test messages or to the remote management software via GPRS
