Time relay with accuracy from 0 to 50 seconds.
- length - 40 mm- width 27 mm- height 21 mm
Power supply 12V DC - Have protection against reverse supply voltage.
12V+ red wire
12V- black Wire
Normally open contact - NO - 20A/12V - wired with two white wiresNormally closed contact - NC -10A/12V - not soldered
- Red wire - to contact switch 12V+
- Black wire to - ground - 12V-
- Two white wires - in parallel wiring to front lights switch
Time is adjusted by trimmer
Principe of work:
When power is on, the delay time start, led diode lights. When set time end, the relay is activated and output NO contact is closed, NC contact is open, until cut off the power. By restart power supply - cycle repeat.Device have plastic box, as see on the picture.
It can be used for example for delay on of car lights. When ignition is start - the timer will wait (1-50s) and then will start the front lights, to save the car battery. When ignition is off - the lights will cut off immediately. The timer need to receive 12 from contact key and output to be wired to front lights switch.
