GND The DC supply of the module is also the reference GND of the signal voltage.
IN signal voltage input, low level below 1V, high level above 1.5V, uncertain in the middle. Up to 30V
Normally open contact of the NO relay
Constant contact of NC relay
COM relay contact common
Instructions:
Time range setting:
– When the selector switch is placed in the 30 position, it means 0-30 adjustable
– When the selector switch is placed at position 300, it indicates that 0-300 is adjustable.
Adjustment of time value:
– Adjustable resistance rotates counterclockwise to the direction of the number to reduce the time, clockwise to the + direction increases the time
Time unit setting:
– When the selector switch is placed in the Sec position, the unit is: second
– When the selector switch is placed in the Min position, the unit is: minute
Example:
Request a delay of 50 minutes:
1. The range is placed at 300 position
2. The time unit is placed in the Min position.
3. Adjust the adjustable resistance to 50 position, adjust to 300, so adjust to 1/5 is 50.
Note: The potentiometer adjustment can also be quickly adjusted with the multimeter voltage file. For example, the range is 30, and it needs to be adjusted to 12, then the voltage can be adjusted to 2.
t=Ut/5*30=2.0V / 5.0V * 30 =12
Ut is the voltage measured by the multimeter, 30 is the range selected by the selector switch, and can also be selected to 300.
Applications:
Combined with the travel switch and the inductive switch:
I bought one for us. And to be honest I was VERY SCEPTICAL. But once installed the sky is the limit on what you can do. Our kids are grown with their own children and even the grandchildren know how to operate it and love the video options. So we decided to get them their own and not to brag but mom and dads gift were the bomb. Even the grandchildren were excited
After having it for a few days I love it! I tried it with different cups and mugs and you’ll want to use the a mug with a flat base to really spread the heat. I pre heat my mug while my coffee brews and it will stay hot as long as you’d like. I found the default high heat setting worked best for me. It’s not to expensive and makes a great gift. I got mine in black and it looks great on my desk at work.
This thing really works. If you are reading a review that says it doesn’t then they r either not using it correctly or using the wrong product. I did not get paid to use this product or my personal opinion like others. I didn’t want to spend all the extra money on a fancy brand name with the same results. My pics will speak for themselves.
Arrival a few days before the scheduled date, very satisfied. Well packaged, received intact and functional, perfect for sketches, simple design but good for the price. Comes with an anti-loss strap, and the pen easy to store.
