USER DIAGRAM CAR POSITIVE & NEGATIVE ACTIVATING TIMER SWITCH RELAY 0-90s 20A Delay Off 12V

Description: This time relay is designed to control the delay-off function of car front lights, helping to prevent battery drain by ensuring that lights automatically turn off after a set period. It features adjustable timing from 0 to 90 seconds and is capable of handling up to 20A for normally open (NO) contacts.

Specifications:

• Timing Accuracy: 0 to 90 seconds
• Dimensions (Plate): 33mm x 16mm x 13mm
• Relay Output:
  • NO Contact: 20A/12V DC (wired)
  • NC Contact: 10A/12V DC (not wired)
• Wiring:
  • Red Wire: Positive 12V+
  • Black Wire: Negative 12V-
  • Two White Wires: Normally open contact of the relay
  • Orange Wire: Activating 12V+ input (to contact switch)
  • Blue Wire: Negative activating input - 12V-
• Power Supply: 12V DC with reverse voltage protection
• Trimmer Adjustment: Rotate clockwise to decrease time, counterclockwise to increase time

Working Principle: When power is supplied, the relay waits for a 12V+ or 12V- pulse at the activating input (orange or blue wire). Once a pulse is received, the timer activates, closing the contact between the two white wires, and holds that position for the set time. After the set time elapses, the relay opens, and the lights turn off. If a new pulse is received, the cycle repeats.

Example Application: Delay-Off for Car Front Lights

• Orange Wire: Connect to the contact switch.
• Red and Black Wires: Connect to the car battery (through a 1A fuse).
• One White Wire: Connect to the front light.
• Second White Wire: Connect to 12V+.
• Other Front Light Wire: Connect to 12V-.

Operation: When the contact switch is turned on, it sends a 12V+ signal to the timer, closing the relay and turning on the lights. When the contact switch is turned off, the timer begins counting down, keeping the lights on for the set duration (up to 90 seconds) before turning them off.

Important Note: If the power consumption of the lights exceeds 20A, a separate, more powerful relay must be used in place of the bulb in the schematic to avoid damaging the timer.

Wiring Diagram: The wiring diagram for this setup ensures proper connection and safe operation of the timer with your car’s electrical system. Follow the schematic carefully to ensure correct installation and functionality.
