Disconnects from the load when the relay is triggered. 3. Key Functions & Modes
The DVB01 operates using five distinct logic modes (F1–F5). To switch modes, long-press the button.
The relay pulls in (turns on) only when the voltage is between V1 and V2. dvb01 user manual
Positive terminal of the voltage being measured (Source).
While the DVB01 can measure up to 100V, the relay is a mechanical switch. Always ensure your load does not exceed the rated amperage (usually 30A), and use an external fuse for high-current applications to prevent fire hazards. Disconnects from the load when the relay is triggered
Press SET again to toggle to the second voltage limit and repeat the adjustment.
The relay pulls in when the voltage is below V1 or above V2. 4. Programming Instructions To set your Upper (V2) and Lower (V1) thresholds: To switch modes, long-press the button
Ensure the V- and DC- are properly grounded. If measuring a battery that is also powering the module, ensure the wiring is secure to avoid voltage drops.
DC 5V, 12V, or 24V (depending on the specific model version). Voltage Detection Range: 0–100V DC. Resolution: 0.1V. Relay Load Capacity: 30A/250VAC or 30A/30VDC.
