5: Working current 40MA
describe:

1 Working voltage: DC 12V (DC 10-15V)
2 Standby current 9MA
3 Working current 40MA
4 Dimensions: 44mm X 29mm X 19mm
5 Weight: 19 grams
6 Maximum load: 10A/250VAC, 10A/125VAC, 10A/30VDC, 10A/28VDC, 10A/12VDC

There 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 port
The water pump is connected to the COM NO port and automatically pumps water from the water tower

notes:
The probe (wire) is not included in the package. No need to use special probes, use household wires to make probes
For safety, please use a well-isolated DC power supply


application

Automatic water supply system for household water tower
Aquarium fish tank water changing system
Automatic filling of water tower
Automatic pumping of water tower
Conductive liquid automatic control
Automatic feeding system for poultry and livestock
Farm automatic water supply system
And other occasions that require automatic water supply and water change.
Solenoid valve water pump motor automatic control

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):
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.
