Remote Terminal Units (RTU)
These are small units with several inputs and outputs, installed in the field at a distance of a few km from the controller. The unit is connected locally to the elements (solenoids, meters, sensors etc.), it is constantly in communication with the controller receiving operational command and transferring data back to the controller.

There are 3 types of RTU:
The system consists of a CRTU adapter inserted into the controller, a 3 wire single cable that can be up to 6 km long along which the CRTU units are installed.
A combination of units with a total of up to 128 outputs can be installed along the cable. Two such cables can be installed on one controller.

There are two basic CRTU models
Cable RTU (CRTU)
The system consists of a CRTU adapter inserted into the controller, a 3 wire single cable that can be up to 6 km long along which the CRTU units are installed. A combination of units with a total of up to 128 outputs can be installed along the cable. Two such cables can be installed on one controller.

• CRTU-4: 4 Outputs - 12 VDC latching, 8 Inputs (On/Off),
4 Analogs - 4-20 mA or 0-10 V

Radio RTU AP (1 way RRTU)
This system transmits a radio signal from the controller to a distance of up to 5 km (depending on the field conditions), the signal is received by the radio RTU and can open or close outputs. (This unit does not include inputs).
The system consists of:
• Serial Transmitter (SRT): includes: 1W-RRTU adapter (located inside the controller), data cable, radio transceiver and an antenna.
• Field Units: includes:
• 2 or 4 12 VDC latching outputs

• Each unit is loaded with its own "private" code number using a portable terminal.

Radio-Gal (2 way RRTU)
The controller is connected via radio to units that consist of outputs, inputs and analogs. The controller scans the units in the field via radio, transmitting the command to open or close outputs and receiving the data from the inputs and analogs. During each scan cycle the controller receives the number of pulses entered and the time (in milliseconds) between the last two pulses thus assuring that pulses can't be lost in the air. The system consists of:
• Transmitting Unit: That includes an interface card inside the controller a radio transceiver and an antenna.
• Field Units: Each unit includes:

The console can be installed in 3 positions in the controller casing (on the front door or on the top or bottom of the casing).

Memory Backup
The RAM is backed up by a lithium battery, installed on the main board that lasts for at least 5 years thus assuring that data is not lost even in the event of power failure.
　

Communication Ports
• One RS-232 port output for communication with a remote PC.
• One RS-485 port for connection to an expansion unit or ECpH monitor.

Galileo - Central PC Computer
　

The advantages of connecting the controllers to a PC are:
• Remote Control: Instead of working out in the field it is possible to carry out the same tasks from the comforts of your air conditioned office.
• Central Command: Several Galileos can be connected to one computer, allowing the control of a very large area from a single location.
• Graphical Presentation: It is possible to see an on-line presentation of the field showing all active elements and the system status in an understandable, familiar way.
• Data Acquisition: The computer can collect a variety of types of data such as Valve Accumulations, Water Meters, Water Meter Flow Rates, Irrigation Information and more.
Many types of reports and graphs can be shown. The reports can be set for ranges varying from a single hour up to a full year. Some of the reports are highly specialized, for example a report of fertilizer elements (nitrogen, phosphorus, potassium etc.) per valve.
The data can be exported to an Excel data sheet for further analysis.

Communication with the central computer:
• Direct connection - by cable up to 20 meters.
• Long distance cable by a special cable modem (L485), up to 4 Km enabling controller networks.
• Cellular modem (including GPRS).
• Radio communication - range of up to 20 km. Extra range can be achieved via repeaters.

Galileo - Software Description
Several types of software (applications) can run on the same previously described hardware. The different application is selected according to the type of project.
The available applications are:
• Open Field irrigation
• Green Houses
• Irrigation
• Climate
• Nursery irrigation

The Open Field Irrigation Application
This unique application is designed to provide a solution for a wide variety of irrigation needs. It can be used in very small irrigation systems such as a home garden or for the largest systems such as irrigation communities. The system fully supports the use of cable and radio RTU. The Open Field PC Software is graphic and allows the user to draw a realistic picture of the field.

Setup Features
Pipe Lines & Main Valve (up to 70)
In this unique system each pipeline can be connected to another pipeline thus enabling defining the pipelines as a network.
The pipelines can be set in the same way as they appear in the field.
This enables:
• Hierarchy of main valves and head definition.
• Gradual opening and closing of irrigation to prevent high pressure buildup.
• Flow rate limit to a pipeline (in the case of bottle necks). Upon programming the limiting flow rate, the system does not allow the actual flow rate to exceed the limit by detaining irrigation programs when the flow rate is already too high.
• Protection of definition errors such as fertilizer pump not in route to the valve using it.

Green house Climate Control
The system includes a large diversified and flexible software package that can be fitted to the use of almost any farmer without any special modifications.

Climate System Sensors
• Internal Sensors in the greenhouse includes: temperature, humidity, CO2 and more.

• External Sensors includes: wind velocity and direction, radiation, rain meter, external temperature and humidity and more.
• The normal temperature, humidity and radiation are carried out by a central program of requirements according to the day segmentation. The day (24 hours) can be divided into up to 8 segments each having required temperature, humidity and radiation. The control is carried out (according to the element setup) to maintain the required condition throughout the day.
On the basis of the above sensors the system operates the greenhouse components.
Up to 4 greenhouses climate controlled systems can be setup each containing
Windows (Curtains) (up to 10 - including roof windows): Each of the windows can open up in 10 stages according to temperature, humidity, wind, rain, logic conditions and processes such as CO2 and spraying.
Fans (up to 4)
Refers to the fans installed on the side wall of the greenhouse and exhaust the air outside the green house letting fresh air into the green house from the opposite wall. Up to 4 groups of fans can be controlled per greenhouse. The fans can be programmed to work according to the conditions mentioned for the windows along with cyclic programs that can change the cycle automatically according to the temperature. The fans can be dependent on other process in the same way as the windows.
Thermal Screens (up to 4)
An element in the greenhouse that can be spread or rolled up according to the level of the radiation and/or the temperature.
Up to 4 opening stages can be setup.
Cooling System (up to 4)

Heating System (up to 4)
The methods of heating the greenhouse are either hot water heating or air heating. The heating system is normally programmed to maintain a certain air temperature by starting and stopping the heating output. When greater accuracy is required or in more severe conditions a special program of "Circulating Heating" is available, allowing PID control of the water temperature, according to the air temperature and the heating conductivity data of the greenhouse. Heating can be dependant on humidity and other conditions.
CO2 Enrichment (up to 4)
A program controlling the operation of the CO2 valve.
The process of CO2 may include some other elements such as windows, air circulating etc.

Air Circulating (up to 6)
Refers to fans installed inside the greenhouse that cause air circulation inside the greenhouse. The programs of these elements include cyclic operation according to temperature, humidity and processes such as spraying, CO2 and many others. This same element can be used also for lighting and others.
