Product introduction:
5V/12V time delay relay module, using high quality relays, maximum current up to 10A, the module uses double-sided FR-4 PCB board, the whole module layout is reasonable and beautiful.
Using original high performance time delay chip, better performance.
With a delay time adjustment potentiometer, the shortest 0.1S, the longest up to 1 hour, with anti-power reverse protection diode, can effectively protect the product.
Module can be used in car recorder, GPS start protection, household appliances, electronic equipment protection, PLC control, industrial control, electronic experiments, arduino robot and other types of control occasions.

Interface description:
when the module on the S6 jumper cap inserted, S7 is not inserted, the block as soon as the power supply is turned on, then immediately start timing (time range is adjustable), while the relay is immediately absorbed, the common terminal of the relay and the normally open end connected, the end of the time delay, the relay is released, the common terminal and the normally closed end connected.

Special Reminder.
Relay control AC 220V or other DC power supply voltage greater than the VCC terminal, can not plug the jumper cap S5.
If S5 is plugged in at this time, the high voltage will flow back into the module and will burn the module.
