Talgil - RTU RF G5 - 4 ANA LIN Expansion

The LIN Expansion series extends the capabilities of the Talgil Modular RTU and DREAM2 controller, offering flexible I/O options to meet a wide range of field application needs.

Compatible with RTU RF G5 (in G5 FAST mode) and DREAM2 Controllers, LIN cards connect via the dedicated LIN Port and support both parallel connection and automatic detection by the Master unit.

Each LIN card must be assigned a unique address when multiple cards of the same type are used. The Modular RTU auto-detects the card type and address, seamlessly integrating the data into the system.

Power Requirements:

When using a LIN Expansion with the Modular RTU, a 12V DC power supply is required. Connect the rechargeable battery to the BATTERY input on the power supply plug. Charging is supported via an 18V DC source (solar panel or power supply) connected to the CHARGE input.

Available LIN Expansion Models

At this stage - the following LIN Expansion Models are available:

• 4 ANA LIN (4 ANALOG INPUTS)
• 840 LIN (8 OUTPUTS / 4 DIGITAL INPUTS / 0 ANALOG INPUTS)
• MODBUS LIN (
• SDI LIN (

In G5 Fast, there is an option to connect several LIN cards in parallel. When connecting several LIN cards of the same type to the RTU Modular, set up a unique address for every LIN card. The RTU Modular automatically detects the LIN card type, and LIN card address, and transmits the LIN card type, address, and the LIN card Data to the Master unit.

4 ANA LIN Expansion Module:

Designed for high-resolution analog input, this expansion card reads up to 4 standard analog sensors (either 4–20 mA or 0–5 V).

• Resolution: 16-bit
• Configurable Parameters: Sampling rate, powering time, averaging, hysteresis, and more.
• Programming Tool: Workbench PC software

4 ANA LIN Expansion - Installation & Wiring Instructions:

For installation & Wiring instructions - visit the page here

1. Use the two dip switches called ADDRESS to set the 4 ANA LIN card address.
2. Use the 4 dip switches to set up the Analog input types.
   - When the Dip switch is 'OFF', the Analog input type is Voltage.
   - When the Dip switch is ON, the Analog input type is Current.
   
   For example, if Analog input 1 is Voltage (0-5V), put the dip switch 1 on V (turn OFF dip switch 1). If Analog input 2 is Current (4-20mA), put the dip switch 2 on mA (turn ON dip switch 2).

1. Connect the Analog sensor wires to the Analog input terminal block. The Analog input terminal block has 3 screws. VS, AIN, and G where VS is the 12V DC power supply, AIN is an input for the Analog data (Analog Signal), and G is a Ground.
   - Types of Analog sensors: Read the Analog sensor specification document or Datasheet to identify the Analog sensor type, Powering time, wiring, and the range. A Passive Analog sensor should be powered before reading the Analog value. It is also called excitation time. On the other hand, an Active Analog sensor should not be powered. To read a Passive analog sensor, If the Analog sensor has 2 wires, connect the Positive wire to VS and the negative wire to AIN.
   - To read a Passive analog sensor, If the Analog sensor has 3 wires, connect the Powering wire to VS, the DATA (Signal) wire to AIN, and the Ground wire to G.
   - To read an Active analog sensor, connect the DATA (Signal) wire to AIN, and the Ground wire to G.
2. Connect the LIN communication cable to the LIN port on the 4 ANA LIN card where 12V is a 12V DC power supply (Red), GND is the Ground (Black), and DATA is the LIN communication (Green).
3. The maximum length of the LIN cable is 10 meters.
4. Connect the LIN cable to the LIN port on the RTU Modular.

About Talgil RF G5

The Generation 5 RADIO RTU system of TALGIL offers a perfect solution for controlling distributed irrigation systems, eliminating the need for costly and complex cabling and the potential for future cable integrity issues.

The G5 RADIO RTU system was launched in 2018; it is based on all the accumulated experience in TALGIL of thousands of wireless systems installed and supported during the past 20 years. The system utilizes low transmission energy, and therefore, no licensing is required.

Under good conditions, the distance between two units in the communication chain can reach a distance of 3 km, but the full coverage of the system is much larger since the G5 RTUs can serve as ROUTERs for other RTUs with up to 11 levels of repetition (total of 30km).

The G5 radio RTUs are energized by rechargeable batteries, ROUTERS are energized by solar cells with rechargeable batteries. For energy-saving purposes, the outputs activated by the system are pulse-latching. Therefore, they are suitable for use where no electric energy exists.

The bidirectional communication between the RTUs and the control unit enables not only activating remote outputs but also reading remote inputs, both digital and analog. To ensure information integrity, each communication gets a confirmation signal, and failure is followed by retries.

Features and Benefits

• The point-to-point distance of up to 3km can be multiplied up to 11 times by using the RTUs as routers for others.
• Bidirectional communication.
• Powered by battery or solar energy.
• Up to 999 RTUs per channel.
• Automatic selection of the suitable frequency out of 16 optional channels.
• Automatic selection of the most suitable routing option.
• License exempt.
• Asynchronous communication
• I/O test mode
• Automatic shutdown of outputs on communication loss and automatic recovery when communication is regained.
• Visual and sound signaling of statuses by LED and buzzer.
• Reporting RTU low battery
• Configurable wake-up signals.
• Existence of diagnostic RF sniffer tool.

Typical Applications

• Irrigation control and management of medium and large farms.
• Centralized irrigation control of multi-crop and multi-irrigation sections operation.
• Monitoring, analytical planning, and irrigation control tools.
• Climate and other environmental parameters monitoring and control
• Where sophisticated irrigation methods are required
• Central control of a large number of control valves grouped together and spread over separated and large geographical areas
• Farms in remote areas that require remote control over cellular communication
• Projects requiring control of multiple and various types of water sources
• Irrigation Schemes - Offtake/Turn-Out

Additional Features and Benefits

• Self-healing network – If an RTU loses communication with the master antenna, it will find an alternative route automatically.
• Automatic frequency selection – In case the frequency used by the system becomes too noisy due to interferences, the system will switch automatically to a different frequency.
• Communication retries – In case interference occurred exactly at a time an RTU was trying to communicate; the system will retry to send the message up to 3 times more.
