What is DH48S-S : Cycle Relay Timer

DH48S-S is a cycled on-off switching timer.Means external device connected to the timer will automatically turn ON and OFF after a specified interval. ON and OFF intervals are independently adjustable, i.e. 2 minutes ON and 5 minutes OFF in a loop.

Timer will consume a maximum of 2 watts for operation.Timer should work on AC110V, AC220V. Timer size is similar to the size of postage stamp.You can read all the specifications at the product buying page.

Where to Buy ?

Buy now for $5 From Aliexpress. If you live outside China then order placed on aliexpress can take upto 30 days to be delivered. If you can’t wait that much then buy from Amazon but for $17.

Some Applications of DH48S-S

Applications are limitless.Some of which that comes in my mind right now are as follow.

  • Turning your mining rig Off after every 10 hours for 10 minutes (automatic On-Off).
  • Exhaust fan On-Off in loop. I use this timer with exhaust fan, making fan off for 5 minutes then on for 1 minute in loop.
  • To turn a room air freshener on and off automatically.
