Wiring diagram - DRL mini timer switch time relay 1 to 20 sec kit 12V / 20A Delay ON car daylight

Dimensions:

  • Length: 38 mm
  • Width: 24 mm
  • Height: 19 mm

Output:

  • Normally open contact (NO)
  • Normally closed contact (NC) – not soldered (see pictures)
  • Common terminal (COM)

Power Supply:

  • Voltage: 10 to 14 V DC

Relay Specifications:

  • 20A/12V DC NO contact
  • 10A/12V DC NC contact

Features:

  • Adjustable timing: 0 to 20 seconds (adjusted by trimmer)
  • LED indication for activated relay

Important Notes:

  • The timer will not function if the power supply is below 10V.
  • Setting the minimal time may cause the relay to click upon powering on (not recommended).
  • The output does not have voltage; a separate power supply is needed for the load (see diagram).
  • For loads exceeding 20A, use a separate powerful relay after the timer.

Principle of Operation:

  • When the power is on, the delay time starts, and the LED diode lights up.
  • Once the set time elapses, the relay activates, closing the output contact until the power is cut off.
  • Restarting the power supply resets the cycle.

Application Example:

  • The timer can be used for delaying the activation of car lights. When the ignition starts, the timer will wait (0-20 seconds) before turning on the front lights to conserve the car battery. When the ignition is turned off, the lights will immediately deactivate. The timer requires a 12V input from the contact key, with the output wired to the front light switch.

Important:

  • The output does not provide 12V power; it only opens and closes the circuit. You need to obtain power from the car battery.
