Irrometer WS-DC Watermark Water Switch AC & DC | Watermark Soil Moisture Sensors by Irrometer
The Water Switch works with existing valves or controller to improve irrigation efficiency based on plant demand. The module will prevent irrigation cycles by signaling the controller’s sensor circuit or interrupting the solenoid power, when the soil moisture status is wetter than the adjustable set point.
The kit includes one moisture sensor. Nine moisture set points allow for a wide range of variations in plant and soil type. An indicator light flashes to indicate status.
Features:
• WS-DC Works with any battery powered controllers equipped with a sensor circuit
• WS-AC works with AC powered controllers with a sensor circuit or as a common interrupt of the valve wiring
• Suspends irrigation cycles based on soil moisture status
• Nine position switch for variations in plant demand and soil type
• Requires no seasonal adjustments
WaterSwitch AC/DC Specifications
COMPATIBILITY: The WaterSwitch is compatible with AC and battery powered (DC) irrigation valve/controllers. For AC, it can be a sensor input or a common interrupt. For DC, it requires a “sensor” port or wire connection on the irrigation controller.
It will work with normally open or normally closed switch requirements. The WaterSwitch can be used in combination with other climatic sensors (rain, freeze, etc.).
Note: The WaterSwitch provides a dry contact switch closure at a reference moisture level for other control applications such as alarms, signaling, etc. Please contact IRROMETER for more details.
