General Description of 24V DC Cyclic Timer Relay
The module offers advanced functions of start delay, stop delay, and repetitive cyclic operation, and is easy to set using the digital display and intuitive menu.
The relay operates at 24V DC supply voltage and allows timing from 0 to 999 seconds, minutes, or hours. It is the perfect choice for simple automation, DIY projects, or periodic control of electrical loads.

Menu Functions (Codes P0 – P5)
| Code | Value | Meaning | Default |
|---|---|---|---|
| P0 | 0 = seconds 1 = minutes 2 = hours |
Time unit for the ON period | 0 |
| P1 | 0 = seconds 1 = minutes 2 = hours |
Time unit for the OFF period | 0 |
| P2 | ON / OFF | Priority for start or stop in the timing cycle | ON |
| P3 | OFF = infinite N (1–999) = number of cycles |
Number of ON/OFF cycles | OFF |
| P4 | ON / OFF | ON = automatic trigger OFF = manual trigger |
ON |
| P5 | ON / OFF | Lock / unlock buttons | OFF |
Step-by-Step Setup Guide
- Press and hold the “S” button for 6 seconds to enter the programming menu.
- Short press “S” to navigate between codes P0–P5.
- Use “▲” and “▼” to adjust the values of each parameter.
- Double-click “S” to set the ON time and then the OFF time.
- If no button is pressed for 6 seconds, the settings are saved automatically.
- In automatic mode (P4=ON), the cycle starts at power-on.
- In manual mode (P4=OFF), press the “R” button to start the cycle.
Usage Examples
- Repetitive cycle: ON = 10 seconds, OFF = 5 seconds → repeats continuously (P3=OFF).
- Start delay: ON = 0, OFF = 10 seconds → device activates after 10 seconds.
- Stop delay: ON = 10 seconds, OFF = 0 → output remains active 10 seconds after turning off.
Connecting the External Port
For external triggering, you can solder an XH-2.45-2P connector or connect wires directly to the designated pads on the board.
Buttons, sensors, or other trigger devices can be added for additional control.
