Introduction
This manual provides detailed instructions for the ASHATA DC 12V Digital Relay Board. This versatile module is designed for various timing and control applications, including delay, cycle timing, and intermittent timing. It features a dual LED display for clear indication of timing parameters and can handle a maximum working current of 10A and a maximum power of 1500W.
Setup and Wiring
Proper wiring is essential for the safe and correct operation of the relay board. Refer to the wiring diagram below for connection details.
Figure 1: Wiring Diagram. This diagram illustrates how to connect the DC 12V power source and the load to the relay board. Ensure correct polarity for the DC 12V input and proper connection of the load to the relay output terminals.
The relay board requires a DC 12V power supply. Connect the positive (+) terminal of your 12V DC power source to the '+' terminal on the board and the negative (-) terminal to the '-' terminal. The load (e.g., a light, motor, or other device) should be connected to the relay output terminals. The relay acts as a switch, controlling the power to your load. Ensure all connections are secure before applying power.

Operating Instructions
The ASHATA Digital Relay Board features a dual LED display and several buttons for configuration. Understanding these components is key to operating the device.
Figure 3: Front Panel Layout. This image highlights the LED indicator, Timing T1 display, Timing T2 display, Reset button, Set key, and adjustment buttons (+/-).
Key Functions:
- LED Indicator (OUT): Illuminates when the relay is active.
- Timing T1 Display: Shows the primary timing value (red display).
- Timing T2 Display: Shows the secondary timing value (blue display).
- RESET Button: Resets the current timing operation or settings.
- SET Key (Gear Icon): Used to enter programming mode and confirm settings.
- '+' Button (Up Arrow): Increases the timing value or navigates through options.
- '-' Button (Down Arrow): Decreases the timing value or navigates through options.
Setting Timing Parameters:
- Enter Programming Mode: Press and hold the SET key (gear icon) for a few seconds until the display starts flashing or shows a mode selection.
- Select Time Unit: Use the '+' or '-' buttons to cycle through time units: seconds (S), minutes (M), or hours (H). Press SET to confirm.
- Set T1 Value: The T1 display will flash. Use the '+' or '-' buttons to adjust the desired timing value for T1 (0-999). Press SET to confirm.
- Set T2 Value: If applicable for the selected function mode, the T2 display will flash. Use the '+' or '-' buttons to adjust the desired timing value for T2 (0-999). Press SET to confirm.
- Select Function Mode: The display will show a function code (e.g., P-1, P-2, etc.). Use the '+' or '-' buttons to select one of the 18 available function combinations (delay, timing, cycle, intermittent timing). Refer to the product's detailed function table for specific mode descriptions. Press SET to confirm and exit programming mode.
Once settings are confirmed, the module will begin operation according to the selected mode and timing parameters. The LED indicator will show the relay's status.
Maintenance
The ASHATA DC 12V Digital Relay Board is designed for low maintenance. To ensure optimal performance and longevity:
- Keep the device clean and free from dust and debris. Use a soft, dry cloth for cleaning.
- Avoid exposing the module to excessive moisture or extreme temperatures.
- Regularly check wiring connections to ensure they remain secure.
- Do not attempt to open the casing or modify the internal components, as this may void the warranty and cause damage.
Troubleshooting
If you encounter issues with your ASHATA Digital Relay Board, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Incorrect power connection or no power supply. | Verify DC 12V power supply is connected correctly and is active. Check polarity. |
| Relay does not activate. | Incorrect function mode selected, timing values set to zero, or load not connected properly. | Review function mode and timing settings. Ensure the load is correctly wired to the relay output. |
| Display is blank or erratic. | Power fluctuations or internal fault. | Disconnect and reconnect power. If the issue persists, contact customer support. |
| Cannot change settings. | Not in programming mode. | Press and hold the SET key to enter programming mode. |
