Item Description:
Time relay with accuracy from 1 to 90 seconds.
Dimensions(plate) - 33mm/16mm/13mm
Relay output: 20А/12V DC NO contact - wired
10A/12V DC NC contact - not wired
Wired with 10 cm wires:
Red - positive 12V+
Black - Negative 12V-
Two white - Normally open contact of the relay
Orange - activating 12V+ input - to contact switch
Blue - negative activating - 12V-
Power: + , - Have protection against reverse supply voltage.
Power supply - 12V DC
Time is adjusted by trimmer. You can use small screwdriver - rotate clockwise - decrease time, counterclockwise - increase time.
Timer don’t have power consumption when it is in standby mode – ( open relay)
Principle of work:
When power is on, the relay wait for filing a 12V+ pulse, or 12V - pulse at activating input. When it is received - timer is activated ( relay will close the contact between the two white wires) and keep that position, until end of set time.
By filing new pulse - cycle repeats.
Timer can be used for delay off car front lights:
- orange wire is wired to contact switch
- Feeding must be permanent +(red) and -(black) comes from car battery, trough 1A fuse
- One white wire - to Front light
- Second white wire - to 12V+
- Other wire from front light - to 12V -
When contact switch is on – it will send 12V+ to the timer and it will close the relay( the lights will come on). When contact switch is turn off – the timer will start countdown and lights will stay on for the set time ( up to 90s). Then it will go off.
Please note – if power consumption of the lights is more than 20A, must be placed separate powerful relay at the place of bulb at the schematic, to avoid damage of the timer.
