Power supply: AC 9-12V or DC 12-15V

The output is the switch of the relay.

Relay contact capacity: AC 250V 10A or DC30V 10A

Circuit board dimensions: length 6.3CM* width 3.9CM* height 2.5CM

Function: When the water level is low, the relay is closed (the external water pump works) and the red indicator light on the board lights up to start pumping. When the water level rises to a high level, the relay is turned off (the water pump stops working) and the indicator light goes out. When the water level drops to a low level again, the relay is closed again, and the above process cycles. This function is used in automatic water adding equipment to keep the water level between low water level and high water level.

The circuit board is made of FR-4 military grade A material. The tolerance of the material and the stability of some parameters are very strong, which is beneficial to the high price of other materials. The PCB is directly printed with the parameters of components, so it can be directly soldered without referring to the circuit diagram, which is convenient.

1. Double-sided wiring, soldering pads sprayed with tin, and soldering pads treated with increased tin technology can withstand repeated soldering, and are not easy to fall off;

2. Self-deformation bending is not easy to occur (it refers to bending caused by non-human forces), and poor plates will bend with the change of time and environment.

3. The impedance is more stable and reliable;
