Easily set a delay timer onto your system with this timer relay module. The delay time is adjustable by simply adjusting the potentiometer, (0?10 seconds).
Increasing the resistance (R) and capacitance (C) can increase the delay time
Delay time formula: T = 1xRxC. where R is resistance, C is capacitance. For example: capacitance 100uf resistance 100K,
Then T = 1x100000x0.0001 = 10s
Can control AC 220V/10A equipment. (Maximum control equipment 2000W)
Working voltage: 12 VDC
Main Chip: NE555
With relay continuous current protection.
Dimensions: 6.8 cm x 2.1 cm
