Remote Terminal Units (RTU)

The RTUs (Remote Terminal Units) TAURO Series, are essentially intelligent electronic devices, specifically designed for data acquisition, data and alarm transmission and control functions, to be installed at remote locations, serving as efficient front-end for SCADA applications in a variety of industries.

For years, municipalities, manufacturing organizations and others, have used RTUs technology to facilitate the alarm notification, continuous monitoring, data logging and maintenance functions of unattended equipment in all types of industrial plants and applications.

Currently, the preferred method of communicating with RTU technology, is the use of a physical connection (Ethernet, fiber-optic, telephonic lines, etc.) but wireless and cellular GSM/GPRS/CDMA are also viable and recommended options , specially in the case of very remote sites, where it is not possible to count on physical connections.

Continuous monitoring provides personnel with the ability to contact, interrogate and interact with unattended equipment at all times, without having to visit the site.

When combined with alarm notification technology, TAURO RTU scan, detect and report preprogrammed alarm conditions, such as system or equipment failures, out-of-range performance levels, maintenance alerts or security breaches. When an alarm condition occurs, the TAURO automatically contacts predetermined destinations (e-mails to computers or SMS messages to cellular phones) to notify personnel of the location and nature of the alarm.


TAURO series of RTUs include two specific designs:

Model TAURO-2000 has a total of 8 differential analog input channels and a number of digital inputs/outputs and serial ports.

Model TAURO-3000 Series is available with 8 or 16 differential analog input channels and a higher number of digital I/O and serial ports.

TAURO are State-of-the Art data loggers , process control units and data transmitters, all-in-one, supported also in a single printed circuit board, of a high degree of integration. It has been specially designed for covering a large number of applications, in which historical data, process control, real-time data and still images transmission be, totally or partially, needed.

In many industrial applications it is mandatory not only to control a certain process, but also to store and transmit historical data or alarms, in order to be able to obtain statistical conclusions, to analyze the accumulated information or to carry out specific studies about the quality performance of an industrial process.

Key features:

  • Ultra low power consumption of 10 mA @ 12VDC in full operation, and less than 1 mA in stand by.
  • High capacity internal memory of 64 or 128 Mbytes, for data storage.
  • Time-stamped data and alarms recording.
  • Very high resolution by means of a 24 bit A/D converter.
  • Up to 16 or 8 totally differential analog input channels.
  • Up to six serial ports (RS232/422/485, Ethernet, SDI- 12, CMOS).
  • Optional built-in GSM/GPRS/CDMA modem.
  • Full surge protection for all Input/Outputs.
  • Built-in battery-charger for direct connection to 110/220 VAC or Solar Panel (12 V-9 Ah external battery recommended).
  • WEBCAMS compatible for still images transmission.
  • Single board design with integrated strip terminal.
