3. Setup and Wiring
The module features user-friendly screw terminal connections for quick and secure wiring. Ensure all connections are firm before applying power.
3.1 Terminal Connections
- VCC: Positive power supply input (5V-36V DC).
- GND: Negative power supply input.
- OUT+: Positive output to the controlled device.
- OUT-: Negative output to the controlled device.
Important: The output voltage matches the input voltage. Connect your load (e.g., motor, LED strip) between OUT+ and OUT-.

After wiring, apply power to the VCC and GND terminals. The LED display will illuminate, indicating the module is powered on.
4. Operating Instructions
The module features three control buttons: SET, UP, and DOWN. These buttons are used to configure the operating mode and time parameters.
4.1 Basic Button Functions
- SET Button:
- Short press: Enters parameter setting mode or cycles through parameters within a mode.
- Long press: Enters mode selection menu.
- UP Button: Increases the value of the currently selected parameter.
- DOWN Button: Decreases the value of the currently selected parameter.
4.2 Operating Modes (Example)
While specific modes may vary, common timer relay functions include:
- P1.1: Delay ON (Trigger activates relay after a set time).
- P1.2: Delay OFF (Trigger activates relay, then deactivates after a set time).
- P2.1: Cycle Timer (Relay ON for T1, OFF for T2, repeats N times).
- P3.1: Infinite Cycle (Relay ON for T1, OFF for T2, repeats indefinitely).
4.3 Setting Parameters
- Enter Mode Selection: Long press the SET button until the display shows a mode code (e.g., "P1.1").
- Select Mode: Use UP and DOWN buttons to navigate through available operating modes.
- Confirm Mode: Short press SET to select the desired mode. The display will then show the first parameter (e.g., "OP" for ON time).
- Adjust Parameters: Use UP and DOWN to change the value of the current parameter. Short press SET to move to the next parameter (e.g., "CL" for OFF time, "LOP" for loop count).
- Save Settings: After adjusting all parameters for the selected mode, long press SET to save the settings and exit the programming menu. The module will then enter its operational state.
The LED display will show the current time countdown or status during operation.
5. Maintenance
The JXRSKJ DC Relay Timer Module is designed for long-term, reliable operation with minimal maintenance.
- Cleaning: Keep the module free from dust and debris. Use a soft, dry cloth for cleaning. Avoid using liquids or abrasive cleaners.
- Environment: Operate the module within its specified temperature and humidity ranges. Avoid exposure to extreme temperatures, moisture, or corrosive environments.
- Connections: Periodically check screw terminal connections to ensure they remain secure. Loose connections can lead to intermittent operation or damage.
6. Troubleshooting
If you encounter issues with your module, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Module does not power on / LED display is off. | No power, incorrect wiring, or power supply voltage is too low. |
|
| Module powers on but does not control the device. | Incorrect output wiring, load exceeding module capacity, or incorrect program settings. |
|
| Inconsistent timing or unexpected behavior. | Power fluctuations, electromagnetic interference, or incorrect parameter settings. |
