This programmable timer with 4 modes and a display showing this count down is very handy and it is very easy to use. You can set the timer for hours, minutes, seconds, and microseconds.
We also have the 12V version
If you require a timer that you can set physical times, we have the DC 5V Real-time Delay Timer Relay Module.
The 4 Modes:
- P-1: When triggered the relay will activate and the countdown will start, once it reaches 0 the relay will deactivate.
- P-2: When triggered the countdown will start, once it reaches 0 the relay will activate and a second countdown will start, once it reaches 0 again the relay will deactivate.
- P-3: This mode is a loop, a countdown will start, once it finishes the relay will activate and a second countdown will start. When it reaches 0 the relay will deactivate and the process starts over.
- P-4: While triggered the relay is deactivated, when the trigger is removed the countdown starts as soon as it reaches zero the relay is activated.
- After powering up the module, hold the button K1. This will show the modes.
- To cycle through the modes, press button K1.
- Press K2 to enter the desired mode, to cycle through the digits press K2 again(some modes have 2 sets of digits 1 for on 1 for off times).
- Press K3 to cycle through the numbers. 0-9
- After the time is set you can move the decimal space by pressing K3, doing this will allow you to set microseconds, seconds, minutes, and hours.
