Motors12V 2 in 1 Pump Pour Water Automatic Controller Switch Liquid Level Sensor Switch Relay Module for Motor Fish Tank IrrigationSpecifications:Working voltage: 12V( 10-15V)Standby current: 9MAWorking current: 40MASize: 44mmX29mmX19mmMaximum load: 10A/250VAC, 10A/125VAC, 10A/30VDC, 10A/28VDC, 10A/12VDCThere are two purposes for connecting the NO and NC ports of the relay: The water pump is connected to the COM NC port to automatically fill the water towerThe water pump is connected to the COM NO port to automatically pump water from the water tower Interface description:HIGH : Upper limit probeOUT : Output probeLOW : Lower limit probe+ : Power of positiveDC- : Power of negativeNC : Relay normally closed contactCOM : Relay common contactNO : Relay normally open contactApplication:Home water tower automatic water supply systemAquarium Fish tank Water Changer SystemFill the water tower automatically Automatic pumping from water tower Conductive liquid automatic controlAutomatic feeding system for poultry and livestockFarm automatic water supply systemAnd other occasions that require automatic water supply and water exchange.Solenoid valve water pump motor automatic controlWorking principle(Fill the water tower automatically): The water level rises: When the water level is lower than the ''Low level'', the water pump starts to supply water to the water tower; when the water level is higher than the ''High level'', the water pump stops supplying water.Water level reduction: When the water level is lower than the ''High level'', the water pump does not work and the water level continues to decrease. When the water level is lower than the ''Low water level'', the water pump starts to supply water to the water tower.Working principle(Automatic pumping from water tower): Contrary to ''Fill the water tower automatically''Note:1. Due to the light and screen difference, the item's color may be slightly different from the pictures.2. Please allow 1-3cm differences due to manual measurement.3. Package does not contain probe (wire).No need to use a dedicated probe, the probe can be made using household wires.4.
