Time relay with accuracy from 1 to 750 seconds.
- length - 47 mm
- width 23 mm
- height 17 mm
Relay output: 15А/125V DC
12A/24V DC or AC
Have NO contact only
Power: + , - Have protection against reverse supply voltage.
Power supply - 12V DC
Time is adjusted by trimmer PR - 100K
Timer don’t have power consumption when it is in standby mode – ( open relay)
Principe of work:
When power is on, the relay wait for filing a 12V+ pulse at activating input. When it is received - timer is activated and keep that position, until end of set time.
By filing new pulse - cycle repeat.
Timer can be used for delay off car front lights:
- Red wire is wired to contact switch
-Feeding must be permanent + and - comes to car battery
-NO contact to Front light
-Other wire at front light – to 12V-
-Com - to 12V+
When contact switch is on – it will provide 12V+ to the timer and it will close the relay( the lights will cone on). When contact switch is turn off – the timer will start countdown and lights will stay on for the set time ( up to 750s). Then it will go off.
Please note – if power consumption of the lights is more than 7A ( 84w 12V) must be placed separate powerful relay at the place of bulb at the schematic, to avoid damage of the timer.
