The MOSFET model is 20N06, and each output channel is an independent control unit, which does not interfere with each other. If one MOSFET is burnt out and it does not affect the work of other channels, just replace the MOSFET with a new one.
The advantages and disadvantages relative to the relay board:
Advantages: 1 small working current, 8-10MA (12V); 2 no sound when switching states; 3 light weight
Disadvantages: 1 load current is small, within 5A; 2 can only control DC 3.5-30V voltage
V1(V2-V8): Load input positive
GO1 (GO2-GO8): load output negative
G1 (G2-G8): load input negative
Note: The output indicator(CH1/2...8 LEDs) is only valid when there is load power
