The Irritrol Wired Rain Sensor RS500 is a wired rain sensor for standard 24VAC irrigation controllers. It helps prevent unnecessary watering by interrupting the controller schedule when sufficient rainfall has been detected.
The RS500 is suitable for most 24VAC irrigation controllers and includes a 25ft UV-resistant cable for installation flexibility. It uses industry-standard hygroscopic discs to sense accumulated rainfall, with adjustable shutoff points from 1/8" to 3/4" so the sensor can be set to suit the site and watering requirements.
Once the sensor has dried out, the irrigation controller can resume normal scheduled watering. The dry-out rate can also be adjusted, allowing the reset delay to be shortened or extended depending on how quickly the system should return to operation after rain.
The RS500 is a simple wired option for residential and light commercial irrigation systems where rain shutoff is required without adding wireless receiver components. It can be converted to normally open operation if required, making it suitable for a wide range of controller installations.
