Delay Timer Relay Self-Locking Delay On Off Time Switch Loop Module Super 555 Timer DC 5V/12V/24V(DC12V)

The media could not be loaded.  Here is how this works, hope this helps those struggling .To set modesPush button and hold until BLUE LED stops flashingLet go of button and momentarily push until desired mode lights solid and let go.Hold button until BLUE led starts flashingMode is set.F1 DELAY ON/ positive trigger follows delay on pot then relay on. Remove trigger and relay goes off immediatelyF2 DELAY OFF/ positive trigger on follows delay time on pot then turns off ( doesn’t matter if trigger is kept on like F4)F3 LATCHED/ positive trigger on = relay on. positive trigger on again = relay offF4 DELAYED OFF AFTER no positive trigger( relay will stay on as long as there is a positive trigger ), follows delay pot after trigger is removed.

I didn't know it work good.

This is a versatile relay. But the documentation is insufficient. I made the attached Function Diagram to better describe the four functions. The 12 volt model will operate down to 6.6V. I hope it continues to work over time as well as it is working now.(August 16, 2023) I discovered that I made a mistake on the F2 diagram. I have corrected the diagram.

The package was damaged, after opening the envelope like you see in the image. Once I tested it I was able to get the blue flashing light and after hitting the set button I was able to hear the click and see the green light so I assume the device works, it just did not work for what I attempted to do.The following info given just under the device discreption shown below did not fully help.Module InterfaceModule voltage/signal input terminal: With 3-wire interface, all interfaces have wiring terminals, making it convenient for users to use1. DC+: Positive pole of DC power supply2. DC -: Negative pole of DC power supply3. X1: Input signal detection interfaceRelay load output terminal: with 3-wire interface, all interfaces have wiring terminals1. COM: Relay Common Interface2. NO: Normally open interface of the relay, suspended before the relay is pulled in, and short circuited to COM after pulling in3. NC: Normally closed interface of the relay, short circuited to COM before relay engagement, suspended after engagement.It is hard to give a proper rating because I was not able to get it to work. Since I am not an electrician i tried to follow what little instruction that was given on the page and in some of the comments. The 3 ⭐ is for the lack of instruction and connect port is off centered, not sure if it is because of the shipment. The damage to the package and possibly the device is the delivery company fault. Since I am not able to confirm the device works it's a 3 ⭐. I will keep the device just to test.

Very nice

I used this to create a circuit that, when a switch is turned on, it sends power to a piezzo buzzer (beep more so) for a couple seconds. It works fine. I do wish I could have a half second beep, but 1-2 seconds is fine.

I can not figure it out,been at it for about 8 hrs,found nothing on the internet on how to wire this,have a friend that's an ee coming over to see if he can figure it out. Way above my garage mechanics abilities,I'm sure they are great if you can figure it out,came with no directions. Can not recommend unless you know electronics,and not sure how much you need to know.

You can wire underneath the board as shown for com, ground and signal when doing car applications.
