Pump Pour Water Automatic Controller Liquid Level Sensor Switch Relay Module

Feature:1: Widely used2: Simple and easy to understand3: Easy to use4: Standby current 9MA5: Working current 40MASpecifications:1 Working voltage: DC 12V (DC 10-15V)2 Standby current: 9MA3 Working current: 40MA4 Dimensions: 44mm X 29mm X 19mm5 Weight: 19 grams6 Maximum 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 automatic water injection tower at the COM NC portThe water pump is connected to the COM NO port and automatically pumps water from the water towerApplication:Automatic water supply system for household water towerAquarium fish tank water changing systemAutomatic filling of water towerAutomatic pumping of water towerConductive liquid automatic controlAutomatic feeding system for poultry and livestockFarm automatic water supply systemAnd other occasions that require automatic water supply and water change.Solenoid valve water pump motor automatic controlInterface Description:HIGH: Upper limit probeOUT: output probeLOW: Lower limit probeDC+: positive power supplyDC-: Negative power supplyNC: Relay normally closed contactCOM: Relay common contactNO: Relay normally open contactWorking principle (automatic water injection tower):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 water supply.The water level drops: When the water level is lower than the "high level", the water pump does not work and the water level continues to drop. 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 of water tower):Contrary to "automatic filling of water tower"Package Included:1*controller moduleNotes:The probe (wire) is not included in the package. No need to use special probes, use household wires to make probesFor safety, please use a well-isolated DC power supply
