Even with a physical dvb01 user manual, problems arise. Here is the most practical error-fixing section.
The module typically features a 4-wire input interface and a 3-wire relay output interface: Module Power Input: Positive pole (Available in 5V, 12V, or 24V versions). Negative pole/Ground. Measurement Input: Positive pole of the voltage being measured. Negative pole of the voltage being measured. Relay Output: Common terminal. Normally Open. Normally Closed. Class B Forums 2. Selectable Functions (P-0) The DVB01 includes five preset operational modes: F-01 (Voltage Measurement): Displays the current voltage; the relay does not act. F-02 (Charge Monitoring): dvb01 user manual
: The relay activates when the voltage rises above the upper limit (P-2) and deactivates when it falls below the lower limit (P-1). Even with a physical dvb01 user manual, problems arise
Once you share the manual text or a link, I can produce a write-up that includes: Negative pole/Ground
