Boxed car timer switch time relay 0 - 40sec 12V 20A delay off universal

USER GUIDE - BOXED CAR TIMER SWITCH TIME RELAY 0 TO 40 SEC

Description: This universal time relay is designed for use in various automotive and electronic applications, offering a delay-off function with adjustable timing from 0 to 40 seconds. The device comes in a compact, boxed design and is capable of handling up to 20A at 12V DC for normally open (NO) contacts.

Specifications:

• Timing Accuracy: 0 to 40 seconds
• Dimensions (with Box):
  • Length: 40 mm
  • Width: 27 mm
  • Height: 21 mm
• Power Supply: 12V DC (with reverse voltage protection)
• Wiring (10 cm wires):
  • Black Wire: Negative 12V-
  • Red Wire: Positive 12V+
  • Two White Wires: Normally open (NO) contact of the relay
  • Normally Closed (NC) Contact: Available but not wired
• Relay Capacity:
  • NO Contact: 20A/12V DC
  • NC Contact: 10A/12V DC (available but not wired)
• Time Adjustment: By trimmer (rotate clockwise to increase time)

Working Principle: When power is applied, the relay is activated, closing the NO contact (and opening the NC contact if wired). The relay will maintain this position until the set time elapses. Restarting the power supply will reset the cycle, and the timer will start again.

Important Note: The relay output does not provide 12V; it only switches the connected circuit on or off.

Applications: This timer relay is ideal for automotive uses, such as delaying the turn-off of lights or other accessories, as well as in other electronics where precise timing control is needed.
