Water pump connected to COM NC port automatic water injection tower
The water pump is connected to the COM NO port to automatically pump water from the water tower
notes:
Probes (wires) are not included in the package. No need to use special probes, use household wires to make probes
For safety, use a well-isolated DC power supply

Interface Description:
HIGH : upper limit probe
OUT : output probe
LOW : Lower limit probe
DC+ : positive power supply
DC- : Negative power supply
NC : Relay normally closed contact
COM : relay common contact
NO : Relay normally open contact
Working principle (automatic water injection tower):
Water level rise: 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.
Lower water level: 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 falls below the "low water level", the pump starts to supply water to the water tower.
Working principle (water tower automatic pumping):
Opposite of "autofill water tower"

Water level liquid level control panel automatic water pumping and drainage
product description:
This product is developed according to the actual needs of household, factories and mines for pumping water. It controls the high-current relay according to the detection of the water level of the pool (water tower), so as to realize the control. It has the characteristics of small size, simple wiring, low power consumption, large switching capacity, strong anti-interference, and high functional stability. It can stably realize the automatic start of the water pump to pump water when the pool (water tower) is short of water, and automatically stop the water pump when the pump is full.
Product Specifications:
Power supply voltage: 9V-12V (AC and DC can be used) (Note: For safety reasons, please do not use switching power supply)
Control output: current 0~10A (genuine relay)
Control power: 0~1KW/220V (theoretically can control 2KW)
Board size: 60*50*25mm
This product does not need to purchase additional probes, and the probes can be replaced by household wires.
Note: The so-called probe is a wire that is buckled with a plastic mesh shell, and can be directly sensed with a household wire. Strip the end of the wire about 3 cm to make it a bare wire for direct sensing. In order to be more durable, where the wire ends contact water, it is recommended that the contacts be made of stainless steel. !
Applications:
Automation equipment manufacturers as the choice of supporting products;
Practical teaching for DIY enthusiasts or vocational school students;
Product installation instructions:
In the upper s, the lower x probes, when two of them leave the water, the relays are closed;
When all the probes are soaked in water, the relay is disconnected.
