FN-VN Two-Wire Decoder
Cost-effective large-scale valve control with 80–95% cable reduction
The FN-VN two-wire decoder system controls up to 128 irrigation valves per encoder across up to 4 km of cable — replacing conventional multi-core wiring with a single two-wire communication loop and reducing field cabling by 80 to 95%.
our core strengths
Proven at Scale, Built for Performance
Farmnet manages the variables that determine crop consistency and operational efficiency. Systems are deployed across greenhouse, open-field, and indoor production environments, providing real-time control of temperature, humidity, CO₂, water delivery, and nutrient dosing.
Operating at national scale within the world's largest agricultural economy. Farmnet systems support dense networks of greenhouse and open-field operations across the highest-intensity production regions.
End-to-end production capability. Controllers, fertigation units, and system components are designed, produced, and validated within Farmnet's dedicated industrial facilities.
More than a decade of continuous development in agricultural control systems, refined through multiple technology generations and operational requirements.
Multidisciplinary engineering organisation focused on agricultural automation, control architecture, hardware design, and software systems.
Systems operating across diverse climates and production models—from arid environments to advanced controlled-environment agriculture.
Thousands of systems in continuous 24/7 operation, generating long-term performance data that informs system reliability and design.
