  • 12V NE555 Oscillator Delay Adjustable Timer Relay Switch Module.
  • The working voltage: 12 volts DC
  • The main chip: NE555
  • The delay time is adjustable (0 to 10 seconds)
  • Can control AC 220V/10A systems.
  • Maximum Control Equipment power rating 2000W
  • With power indicator LED and switch trigger timing indication LEDs.


  • Tensile power delay relay.
  • 12V power supply for relay, relay not immediately absorbed and relay outputs status are: disconnected normally open, normally closed and public driving; Wait until the delay 1-10 s (adjustable), the suction relay and, this time, the output status relay is: normally open and public driving, normally closed and public disconnected; While uninterruptible power supply module, this state will be maintained.
  • The delay time is adjustable, (0 to 10 seconds)
  • to increase the potential can increase the delay time
  • Increasing the capacitor C1 can increase the delay time
  • With input power indicator
  • With relay indicator
  • The AC 220 V / 10A can be controlled on the equipment. (Maximum control of equipment 2000 W)
  • with free wheel protection relay

The time delay formula: T = 1.1RC.

  • For example: a capacitor resistance 100 uf 100 K T = 1.1 * 100000 * 0.0001 = 11 seconds
