The module when power is turned on, the timer is started immediately (time range is adjustable), the relay immediately pull switched common terminal of the relay and often the beginning of the end of the time delay, the relay is released, the common and normally closed terminal is turned on.

  • Imported high quality delay chip design, the performance is far better than the 555 chip
  • Delay time range selection, the shortest 0.1 seconds, up to one hour, to meet most of the demand
  • Against power reversal protection diode, the effective protection of the product
  • Can be accessed by high current loads (AC 250V / 10A, DC 30V / 10A)
  • Time delay adjustment potentiometer clockwise adjustment will be more long


The tachograph GPS start protection, household appliances, electronic equipment protection, sound protection, industrial control, PLC control, electronic experiments, Arduino robot, the range of applications is very wide range.
