User Manual: Dvb01

A: Yes, it has an automatic power-saving function that can be set independently by the user.

Available in DC 5V, 12V, or 24V variants (ensure your module matches your power source).

All user settings are saved automatically and retained even when the module loses power. Hardware Interface & Wiring Guide dvb01 user manual

| Menu | Parameter | Range | Description | | :--- | :--- | :--- | :--- | | | Function Select ( F-01 to F-05 ) | F-01 to F-05 | Selects the operating logic for the relay (see table below). | | P-1 | Voltage 1 (V1) | 00.0 to 99.9 | Sets the first voltage threshold for your chosen function. | | P-2 | Voltage 2 (V2) | 00.0 to 99.9 | Sets the second voltage threshold for your chosen function. | | P-3 | Voltage Calibration | Reads current voltage | Critical: Displays the voltage the DVB01 is currently measuring. Use [+] or [-] to adjust the displayed value to match an external, accurate voltmeter reading. |

Verify wiring at the COM/NO or COM/NC terminals. A: Yes, it has an automatic power-saving function

The controller is smart. When you set V1 and V2 , it will automatically determine which value is higher and which is lower. You do not need to program them in any specific order.

If you notice a minor discrepancy between your DVB01 readouts and a professional digital multimeter (DMM), you can manually offset the module's calibration. Disconnect power to the V+ and V- lines. Hardware Interface & Wiring Guide | Menu |
