The Calsense 2-wire technology provides easy and cost-effective installation and expansion of any landscape project using the CS3000 irrigation controller with the 2-wire decoder system. 2-wire designs operate irrigation station solenoids by transmitting signal and power down the same path, avoiding the need for separate wiring for each valve. The 2-wire board allows a single controller to manage up to 128-independent valves, anywhere along a 7,000' cable run.
