Product Overview
The Oumefar Timer Relay Module is a versatile time delay relay converter designed for various applications, including automotive control systems and general electrical equipment. It features adjustable on-time and off-time settings, supports both mon (single) and cycle modes, and includes reverse input protection.
Key features include:
- Protection Function: Supports reverse input protection.
- Trigger Button Switch: For initiating the timing sequence.
- Adjustable Time: Both "on" and "off" times are adjustable.
- Two Modes: Mon mode (single trigger) and Cycle mode (continuous operation).
- Wide Application: Suitable for timer operating equipment, robotics, automation, PLC development, smart home systems, and electronic development.

Setup and Installation
Carefully follow these steps for proper setup and installation of the timer relay module.
- Identify Components: Familiarize yourself with the module's components as shown in the diagram below.
- Power Supply Connection: Connect the power supply to the module. Ensure correct polarity to utilize the reverse input protection. The module supports DC 5V, 12V, or 24V depending on the specific model.
- Load Connection: Connect your load to the relay's output terminals (NC, COM, NO). Refer to the wiring diagram for proper connection.
- Time Range Selection: Use the jumper to select the time range.
- When the jumper is on "T", the time is normal.
- When the jumper is on "T/10", the time is divided by 10 (e.g., 10 minutes becomes 1 minute).
- Working Mode Selection: Use the jumper to select the desired working mode.
- When the jumper is on "Cycle", the module operates in infinite cycle mode.
- When the jumper is on "Mon", the module operates in single (monostable) mode.

Operation
Operating the Oumefar Timer Relay Module involves setting the desired time delays and triggering the module.
- Adjusting Delay Times: Use the two potentiometers on the module to adjust the "on" time and "off" time. Rotate them clockwise to increase the time and counter-clockwise to decrease it.
- Triggering the Module:
- Mon Mode (Single): After powering on, press the trigger switch (start button) once. The load will turn on, and after the set "on" delay time, it will turn off.
- Cycle Mode: After powering on, press the trigger switch once. The load will cycle on and off according to the set "on" and "off" times. Press the trigger switch again to stop the cycle.
- Monitoring Status: The module includes a power indicator and a switch indicator LED to show its operational status.

Maintenance
The Oumefar Timer Relay Module is designed for reliable operation with minimal maintenance. Follow these guidelines to ensure longevity:
- Keep Clean: Ensure the module is free from dust and debris. Use a soft, dry cloth for cleaning.
- Environmental Conditions: Operate the module within its specified temperature and humidity ranges. Avoid exposure to extreme conditions or corrosive environments.
- Secure Connections: Periodically check all wiring connections to ensure they are secure and free from corrosion.
- Component Replacement: If longer delay times are required beyond the adjustable range, it may be possible to replace the capacitor or potentiometer with components of higher values. This should only be performed by qualified personnel.
Troubleshooting
If you encounter issues with your Oumefar Timer Relay Module, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Module does not power on. | Incorrect power supply voltage or polarity; loose connections. | Verify input voltage matches module requirements (5V, 12V, or 24V). Check power supply polarity. Ensure all power connections are secure. |
| Load does not activate/deactivate. | Incorrect load wiring; faulty load; incorrect mode selection; trigger not activated. | Check load wiring against the diagram (NC, COM, NO). Test the load independently. Confirm jumper settings for "Mon" or "Cycle" mode. Ensure the trigger button is pressed. |
| Timing is inaccurate or not adjustable. | Incorrect time range jumper setting; faulty potentiometer. | Verify the time range jumper is set correctly (T or T/10). Ensure potentiometers are rotated within their limits. |
| Module cycles continuously in Mon mode. | Jumper incorrectly set to "Cycle" mode. | Adjust the working mode jumper to "Mon" for single operation. |
