1PCS DC 6V-30V OFF/ON timing switch period 1-channel 5V relay module Time delay relay module triggers 999 minutes Arduino relay board

Relay Module, Off Delay, Off, Trigger Delay, Cycle Time Switching
Continuously adjustable from 0.1 seconds (minutes) to 999 minutes (maximum).

emphasize:
1. Wide voltage power supply (6~30V), support MicroUSB 5.0V power supply, easy to use;
2. The interface is clear and concise, powerful and easy to understand, almost meeting all your needs;
3. Emergency stop function ("stop" key); with reverse polarity protection, reverse polarity will not burn out the product.
4. Increase the sleep mode, if this mode is turned on, if there is no operation within 5 minutes, the screen will be automatically turned off, and any key will wake up;
5. Different OP, CL, lop parameters can be set independently and automatically saved;
6. After the module is powered off, all parameter settings will not be lost.

Operation Mode:
P1: Trigger signal, the relay is turned on for the "OP" time, and then disconnected; during the "OP" period, as follows:
P1.1: Signal reactivated, invalid
P1.2: The signal is activated again, the clock is reset
P1.3: The signal is reactivated, the relay is disconnected, and the clock is stopped;
P-2: Trigger signal, the relay is disconnected for "CL" time, the relay is turned on for "OP" time, and then the relay is disconnected;
P3.1: Trigger signal, the relay is turned on after the "OP" time, the relay is turned off at the "CL" time, and then the operation cycle, if the trigger signal time, the relay is turned off, and the clock is stopped; the number of cycles ("lop") can be set.
P3.2: There is no trigger signal, the relay is turned on for the "OP" time, and the relay is turned off for the "CL" time, and it keeps looping; the frequency period ("lop") can be set;
P-4: Signal hold function. If the trigger signal is cleared for a period of time, the relay remains on; when the signal disappears, after the "OP" time, the relay pulls in; if the signal is different within the timing period, the time is cleared;

scope:
1: Working voltage: 6-30V, support MicroUSB 5.0V. power supply
Once, and then back to the main interface, set the parameters successfully!
Main interface: The relay inactive state displays "000" (no decimal point), and the relay state has a decimal point.
Mode selection interface: long press the "Settings" button to enter, after the setting is completed, long press the "Settings" button to return to the main interface.

"Stop" button extension:
Relay On Mode:
1. On: Relay enable to guide "OP" on time;
2. Off: The lead-out relay is normally closed;
In the main interface, short press the "stop" button to switch between power on and off, the current status will flash, and then return to the main screen. (This function is an emergency stop function, click to turn off the relay)

Sleep Mode:
1. "C-L" sleep mode: no operation for five minutes, the digital display is automatically turned off, and the program runs as usual;
2. "o-d" normal mode: the digital display is always on;
Press and hold the Stop button for two seconds, then release
Toggle the "C-L" and "o-d" states, here is the current state of the flash, and return to the main screen.
