12V NE555 Adjustable Time Delay Relay Module

The delay-vehicle device is turned on, to prevent excessive current when the car ignition burn-vehicle device.

You need to have in order to start the occasion, to prevent multiple devices
simultaneously starting current is too large burning appliances.


  • Power relay delay pull. Specifically 12v power supply to the relay, the relay
  • will not immediately sucked and status relay outputs are normally open
  • disconnected public,normally closed and public conduction,wait until the delay
  • 1-10s (adjustable),the relay suction and, this time, the relay output status is
  • normally open and public conduction,normally closed and public disconnected;
  • as long as uninterruptible power module, this state will remain.
  • The delay time is adjustable(0 to 10 seconds)
  • Increasing the potential can increase the delay time
  • Increasing the capacitor C1 can increase the delay time
  • With input power indicator
  • With relay indicator
  • Can control AC 220V / 10A about equipment. (Maximum control equipment
  • 2000W)
  • With freewheeling protection relay.
  • The delay time formula: T = 1.1RC. For example: a resistor capacitor 100uf
  • 100K
  • T = 1.1 * 100000 * 0.0001 = 11 seconds


  • Size: 6.8CM *2.1CM
  • The main chip: NE555
  • The working voltage: 12V
  • Weight: 30g


  • 1 x NE555 Timer Switch Adjustable Controller Module
