Module features: Length x width = 52 mm x 16 mm. The working voltage of the module is 12 V. The module can control: 10 A 250 VAC (AC), 10 A 30 VDC (DC) or less load. The time can be set via the potentiometer. The default setting is 0-25 seconds. If it takes longer, you can replace the larger capacitor or potentiometer yourself. Delay time formula: T=1.1RC For example: Capacity 47uf resistance 500K T=1.1*50000*0.000047=25.85 seconds. The power supply of the module is equipped with a diode to prevent reverse polarity of the power supply, so that friends can connect safely. The signal end of the M. oduls is with Optocoupler insulation, which has a strong anti-interference ability and can adapt to the application of high and low level control signals and is suitable for industrial control.
