Talgil - DREAM2 - Professional Irrigation Controller

The Talgil DREAM is a professional, Cloud-enabled irrigation management system that combines various hardware, software and communication components together with analytical tools and an advanced user interface into one all-inclusive and powerful centralized crop management system.

The DREAM2 is designed to provide farmers with an expandable, modular, efficient and versatile crop management system that makes efficient use of water, energy, chemicals and manpower resources while increasing yields, produce quality, and profitability.

The DREAM2 can manage irrigation, fertilization and backflush control in the DREAM2 vicinity to irrigation heads connected to end units that are far away from the controller. In addition, the DREAM can read digital, analog and SDI-12 sensors and act according to what was received by them.

The DREAM2 can handle up to 999 outputs. An output can be defined as a Main valve, secondary valve, fertilizer valve, filter, pump or Satellite.

Moreover, the DREAM2 can read hundreds of digital, analog or SDI-12 sensors like water meters, fertilization meters, DP sensors, pressure sensors, humidity, temperature, and so forth.

The DREAM2 is an independent controller that enables it to be programmed by the user using an LCD and keyboard. When there is no reception, the DREAM2 will continue with the planned irrigation program.

The controller can be accessed via the 'Console' PC Software and the 'SPOT' Phone App.

This is our premium controller that has many capabilities and can suit most water/irrigation applications!

The Various I/O Options

Interface for local I/O AC or DC

• The local I/O interface may control 1 or 2 I/O boards of 16 outputs and 8 digital inputs. It is meant for reading digital inputs and activating outputs, which are close enough to be directly connected to the control unit.

I/O Expansion and Remote I/O

• External / Remote I/O is available with the same configuration of outputs and inputs inside an enclosure and is limited to 32 (2 x 16) outputs and 16 (2 x 8)digital inputs. Using multiple Remote I/Os at the same time is possible.

Radio - RF - Interface

• When remote I/O devices cannot be reached by cable, radio-communicated RTUs will be used. The RF INTERFACE will communicate with the RF RTUs through an RF MASTER receiver/ transmitter located on top of a high pole next to the RF INTERFACE. In the field, the RTUs will be placed next to the I/O devices to be controlled.
• The RF RTUs can read digital and analog inputs and activate DC latching outputs. We can have several channels of RF RTUs with up to 60 RTUs per channel. One RF Master can operate 999 RTUs at the same time.

Interfaces for Local Analog Inputs

• Analog inputs can be read through the RF RTU system. However, analog sensors located in the close vicinity of the DREAM 2 controller can be directly connected to the controller by using special interfaces for analog inputs. For that purpose, we may use two types of analog input interfaces; the compact one can handle 2 or 4 inputs, and the modular one can read up to 64 analog inputs, divided into batches of 8.

Interface pH/EC (Fertmaster)

• When the system is required to measure/control the pH (acidity) and the EC (Electro Conductivity) of the water, a special interface will be used. Apart from reading the analog values of the pH and EC electrodes, the pH/EC interface is capable of handling 6 injectors of fertilizers and a booster pump; it is equipped with a display and a keyboard which enable calibrations, parameters setting and monitoring to be done directly at the interface. During the injection process, it receives from the DREAM2 controller all the details and the requirements of the particular process, and it executes the injection accordingly. All along the injection process, the DREAM2 is updated continuously about the status and the results.

THD Interface

• The THD interface is meant to measure the ambient Temperature and Humidity, calculate the actual Dew point and report the three values back to the controller. The values can then be used for frost protection or conditioning of cooling programs. During the configuration process when defining the hardware in use, the THD interface will be defined as an analog interface of the type THD. Like any other interface, it has an address switch that has to be set according to what has been defined in the configuration process.

Weather Station Interface

• The Weather station interface enables the connection of a “Davis - Vantage pro2” weather station to the system.

And many more!
