Model AFIK - Irrigation Controllers

The initiative for the AFIK development came from the agricultural irrigation market, seeking for an optimal solution in controlling stand alone irrigation heads. The AFIK excels in its simplicity of use, low energy consumption, and a gallery of useful technical features.


  • Modular structure – existing in 2, 4, 8, 12 or 16 outputs and 4 dry contact inputs
  • Outputs may be configured as:
    • 0 or 1 main valve
    • 0 or 1 fertilizer injector
    • 1 up to 16 irrigation valves
    • 0 or 9 filter station
  • Inputs can be allocated for 1 water meter, 1 fertilizer meter, 1 pressure sensor, 1 differential pressure sensor. In place of one of these sensors a start by tensiometer contact can be allocated
  • Activating 2 wired pulse latching solenoids
  • Energized by standard alkaline batteries
  • Detecting low battery condition
  • Optional communication for remote programming through a PC (for 2, 4, 8 outputs models only)
  • Optionally utilizing the SMS system for sending alarm messages (for 2, 4, 8 outputs models only)


  • Water dosing by time units or volumetric units, specified per each valve individually
  • The days of irrigation can be set either as a constant cycle or as a RUN-LIST
  • Cycles within the irrigation day (pulse irrigation)
  • Fertilizer dosage by time or by volume
  • Injecting fertilizer continuously or proportionally
  • Fert/water proportion can be specified as: time/time; volume/volume; time/volume; volume/time
  • Three stage fertigation: pre- watering, injection, post watering
  • Main valve operation: delayed, advanced, or simultaneous with the irrigation valves
  • Filter flushing , by time and/ or pressure differential
  • Detecting endless looping problem in the flushing process and converting to flushing by time only
  • High/ low flow control and leakage detection
  • Low pressure wait
  • Optional STOP-TIME definition
  • Manual activation of programs and individual valves
