DC 12V or 24V (depending on model variant, often supports wide input) Measurement Range: 0-99.9V Relay Capacity: Max load current 10A (DC or AC) Operating Mode: ~16mA (12V), Standby ~6mA Dimensions: 65mm × 40mm Display: 3-digit Red/Blue LED 3. Module Interface & Wiring

The DVB01 has five distinct functions (F1-F5) to handle different scenarios, selectable through the settings menu.

Connected to COM when the relay is off; disconnects when the relay triggers. Use this if you want a device to run by default and shut off when the voltage limits are breached. Understanding the 5 Operating Modes

This article serves as a comprehensive guide and user manual for the .

If the module and the load share the same power supply, high-current loads (like motors) can cause a voltage drop that resets the DVB01. Solutions: Use separate wiring for the module and the load.

: Acts as a simple digital voltmeter; the relay does not operate.

The module features three tactile buttons located beneath the digital display: , SWI (Switch/Increment), and NUM (Number selection/Decrement). Step 1: Selecting the Function Mode (F-1 to F-5)

, a multi-functional voltage monitoring controller used for battery protection, charging/discharging monitoring, and precision voltage control.
