You will able to change it later with soldering iron if you need.
You can choose a default range by writing a message with the order.
Delay start time relay from 25s to 31h and 17m that can be set by using ranges at the table.
- length - 50 mm
- width - 37 mm
- height - 20 mm
Have terminals for:
- 12V input , Have protection against reverse supply voltage.
- Normally open contact
- Normally closed contact
- Common terminal
Power supply - 12V DC
Relay: 10A 250V AC
Time is adjusted by a trimmer.
There is a green diode, which indicates the number of counting cycles anda a red diode, which indicates whether the relay is working.
- when the green diode is flashing - it indicates delay progress.
- when the red diode lights - it indicates that the relay works
Method of work:
When power is on, the delay time start, green led diode flashing. When set time end, the relay is activated - green diode lights and output NO contact is closed, NC contact open, until cut off the power.
By restarting power supply - cycle repeats.
Device doesn't have plastic box, as it is seen on the picture.
The delay ranges are changed with make a track between terminals bottom of the plate, with numbers from 1 to 10
regarding setup table. The timer will come with default delay range as you can choice from drop-down menu.
When you set delay range - then time is adjusted by a trimmer.
Using "Trial and Error" to set a long time period would be very tedious. A better solution is to use the Setup tables provided - and calculate the time required to light the red diode.
For example, if you want a period of 9 Hours - the Range table shows that you can use range number 9. You need relay to be activate after 9 x 60 x 60 = 32 400 seconds. The Setup table tells you to divide this by 512 - giving about 63 seconds. Adjust the trimmer so that the Red LED lights 63 seconds after power is applied. This will activate the relay at Range 9 after about 9 Hours.
