Parameter setting instructions:
Press and hold the K1 key, and after 2 seconds, the display screen will show P-x. Press K2 and K3 to change the working mode. After selecting the working mode, press the K1 key briefly to enter the A time setting, and the screen will display Axx. At this time, press the K2 and K3 keys to modify the A time parameter. Short press the K2 and K3 keys to add or subtract 1, long press to quickly add or subtract 10, and press the K4 key to set the position of the decimal point. After setting the A time, press the K1 key to set the B time, and the screen will display bxx. At this time, press the K2 and K3 keys to modify the B time parameter. Short press the K2 and K3 keys to add or subtract 1, long press to quickly add or subtract 10, and press the K4 key to set the position of the decimal point. After setting the B time, (mode) If there is a parameter for the number of C cycles, press the K1 key again to set the number of C cycles. The screen will display Cxxx. At this time, press the K2 and K3 keys to modify the number of C cycles parameter. Short press the K2 and K3 keys to add or subtract 1, and long press to quickly add or subtract 10. After setting, press the K1 key once to exit the setting state and save all parameters.

EC Buying 2Pcs 5V Time Delay Relay ModuleYou can use this to time USB devices, it will require some additional engineering on your end. However, for standard 5V lines it is plug and play. It works well and is easy to set a time on.

I like gizmos and these little time delay modules suit that category to a "T." So, I couldn't resist ordering them.The boards were delivered in 2 days which was just as expected given the estimated delivery date. Everything was in good condition.The boards are small at approximately 1.6" by 2.6".They require 5 volts DC at a few milliamps for operation. The timer, modes and other parameters can be set using the 4 pushbutton switches: K1 through K4.Be advised that these boards come with no printed documentation. The user is advised to retain the operational information from the product page. Additionally, a bit more depth might (might!) be had here:https://www.amazon.com/dp/B07CYMTM5R and on the pages for similar items.Using these devices will likely require a bit of trial and error. However, with a little patience, I have found them to be useful.
