Bermad RTU RF G5

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 about 20 years.

General features

The G5 radio RTU system of TALGIL offers a perfect solution for controlling distributed irrigation systems, when using cable is impossible or undesirable. 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 3-4 km, but the full coverage of the system is much bigger since the G5 RTUs can serve also as ROUTERs for other RTUs with up to 11 levels of repetition.

The G5 radio RTUs are energized by standard Alkaline batteries and those serving as 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 assure information integrity, each communication gets a confirmation signal and failure is followed by retries.The G5 radio RTU has a modular structure with a maximum capacity of 8 outputs and 4 digital/analog inputs. A G5 radio RTU system channel may handle up to 999 RTUs.

RTU RF G5 - Installation example
  • The point to point distance of 3-4km 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 most suitable routing option.
  • License exempt.
  • Asynchronous communication
  • I/O test mode
  • Automatic shutdown of outputs on communication loss and automatic recovery when communication 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.

It has several major advantages over previous generations:

  • Self-healing network – If an RTU loses communication to 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.


The system is built from three main parts:

  • Interface RF + Master antenna – Communicates with the controller / UNILINER unit on side and with the G5 RTUs on the other side.
  • RF RTU – The RF RTU (Remote terminal unit) is basically a small simple controller that performs whatever the INT RF tells it to.


Each RF RTU is capable of:

  • Controlling:
  • Pumps
  • Valves
  • Fertilizer injectors
  • Filters
  • Monitoring:
  • Water meters
  • Fertilizer meters
  • Water floats (Reservoirs and tanks)
  • Pressure sensor
  • Differential pressure sensor
  • Analog sensor – Temperature, humidity, tensiometers, radiation, CO2, water level and ect..


The maximum range between the controller and the furthest RTU is 2.5 km (with line of sight). The G5 is capable of 10 levels of repetition, which means a single RF INT can control & monitor elements in a 25km radius!

Each INT RF is capable of communicating with up to 600 RF RTUs. The communication with all the RTUs is done every couple of seconds (Depending on the number of RTUs)


Energy options:

  • 4 X “D” type alkaline batteries – Modular RTUs
  • 4 X “C” type alkaline batteries – ECO RTUs
  • 5W solar panel + 12V 3.3aH rechargeable battery
  • 5W solar panel + 12V 1.3aH rechargeable battery (For units with analog inputs)


The RF system uses the ISM bands (433 / 868 Mhz) and a 10mW transmission power and therefore it is a LICENSE FREE SYSTEM. The outputs can control 12V DC latch solenoids.


There are several RTU RF models:

  • RTU RF ECO – An economic non modular solution, to be used where devices in the field are far away one from another and future expansion in not likely.
  • 1 Output / 1 Input / 2 analog input (4-20mA / 0-5V)
  • 2 Outputs / 2 Inputs / 2 analog input (4-20mA / 0-5V)
  • RTU RF MODULAR – A modular solution, to be used where devices are grouped together or a future expansion is possible.
  • 2/4/6/8 outputs
  • 0/4/8 digital input
  • 0/2/4 analog inputs (4-20mA/ 0-5V, SDI–12)


Programing is done easily by using the mini rotary switches (Besides an RTU with analog inputs, which requires a connection to a PC / Laptop)
