6-20V 1-Channel Power Relay Module with Adjustable Timing Cycle

This is a 6-20V 1-Channel Power Relay Module with Adjustable Timing Cycle and a Digital LED display, commonly used in Home Automation Delay Timer Control Switch Modules and Timer Controllers.

Operation Modes:

– P1: Trigger signal activates the relay for the “OP” time period and then disconnects. Additional triggers during the “OP” time can either be invalid, reset the clock, or terminate the timing.

– P2: Trigger signal activates the relay after the “CL” time off period, and the relay stays on for the “OP” time period. Once timing is complete, the relay disconnects.

– P3.1: Trigger signal activates the relay for the “OP” time period, followed by the “CL” time off period, and cycles these actions. The number of cycles (“LOP”) can be set. Another trigger signal within the loop stops the relay and timing.

– P3.2: Similar to P3.1, but no trigger signal is needed after powering up.

– P4: Signal holding function. If the signal is triggered, timing is cleared, and the relay remains on until the “OP” time is over. Another trigger during timing resets the clock.

Setting Time Intervals:

Parameters include OP power-on time, CL power-off time, and LOP cycle times (1-999 times, “—” for unlimited cycles).

How to Set Parameters:

1. Choose relay operation mode.
2. Enter selection interface mode by long-pressing the SET key for two seconds.
3. Use the UP and DOWN keys to select the mode setting (P1.1 to P4).
4. Short press SET to set the corresponding parameter. The parameter will flash, indicating it’s ready for adjustment.
5. Use UP and DOWN to set the parameter value. Long press for quick adjustment.
6. Press STOP to choose the decimal place for the time interval (0.1 s – 999 min).
7. Short press SET to set the current mode’s next parameter.
8. After setting all parameters, press and hold SET to save and exit.

Mode Select Interface:

Long-press SET to enter, and long-press again to return to the main interface after setting.

Activate Relay Mode:

– NO: Relay connects during the “OP” time.
– OFF: Relay is off.

Sleep Mode:

After 5 minutes of inactivity, the display turns off automatically.
