UNILINER

When connected back to back with any existing controller the UNILINER bus-system can receive 32 output command lines and send back 16 input signaling lines. The output commands generated by the controller will be transmitted to the remote valves and signals of remote sensors will arrive back to the controller through the RTU units distributed in the field.

To communicate the RTUs, the uniliner can use either 2 wired cable or radio communication. The Uniliner is a DC powered unit and it activates pulse latching solenoids, therefore it can be powered by solar energy and used where no electric power exists.

  • The UNILINER has been designed to work in conjunction with irrigation controllers of any type for the purpose of improving the deployment ability and increasing the radius of operation of the controller. The UNILINER connects to the input/ output terminals of the controller and serves as a bridge to remote valves and sensors that may be located far beyond the range originally covered by the controller. Utilizing efficient radio or cable operated infrastructure The UNILINER offers a reliable and energy saving solution when remote accessories need to be controlled.
  • The UNILINER is attached to the I/O terminals of the irrigation controller in place of the solenoids, water meters, fertilizer injectors or any other controlled accessory. The open/ close commands initiated by the controller are transmitted to the remote valves, and signals originated at the remote sensors are brought back to the controller's inputs.
  • Using a 2 wired cable with a cross section of 1.5 mm2 a distance of 10 km can be reached. Alternatively radio operated RTUs offer a cable free connection to remote accessories. The radio system does not need any licensing because of the frequency used and the low transmission power. Under good conditions, in an open field with no obstacles, a distance of 2 km can be reached. The distance can be doubled by making some RTUs act as repeaters.
  • The RTUs installed in the vicinity of the remote valves and sensors, are of a modular structure- 2,4,6,8 outputs and 4 or 8 inputs (8 inputs exist only when using the 2 wired system). In one case the RTUs are connected through the 2 wired cable, receiving both the energy and the communication through the same 2 wires. In the second case the RTUs are equipped with radio receivers/ transmitters and they are powered locally by dry batteries or rechargeable batteries with solar panels. It is important to notice that the radio RTUs are communicating bidirectionally, receiving commands from the center and returning the sensors status back to the center.
  • Up to 60 RTUs can be connected through the 2 wired or the radio channels. There is also an option to use the SAPIR type Edge Units with a 4 wired cable and then the limit is 30 Edge Units.
  • The RTUs will operate 12v DC 2 wired pulse latching solenoids.
  • The UNILINER is equipped with a control panel for making definitions and for testing the system's operation.
  • The UNILINER detects and reports malfunctioning RTUs.
  • The software enables grouping valves together to be irrigated in the same shift. The controller activates a single output but really the whole group will open.
  • The UNILINER is a DC system that can be fully powered by solar energy.
