DC 5V Voltage Detection Relay Switch Board Charge and Discharge Protection Detection Upper and Lower Limit Alarm Control Module

EU LVD Voltage : Low voltage: Below 50Vac or 75Vdc High-concerned chemical : none Power Source : DC Theory : Voltage relay Model Number : Voltage detection relay Brand Name : Stlxy Voltage : 5V Origin : Mainland China

1: It can detect DC voltage between 0~50V, and the relay output can control the on/off of lines within 5A. 2. Adding a ms level delay time to prevent output oscillation and damage to the entire circuit. 3: Measurement accuracy of 0.04V, can be turned off for a long time to reduce power consumption 4: Input voltage: DC 5/12/24V optional 5: Function Description: P-1: Charging monitoring: When the measurement is below voltage V1, the relay is closed, and when the voltage is above V2, the relay is disconnected; P-2: Discharge monitoring: When the measurement is higher than voltage V2, the relay is closed, and when the voltage is lower than V1, the relay is disconnected; P-3: Off range closing: When the measured voltage is between V1 and V2, the relay is disconnected, and in other cases, the relay is closed; P-4: In interval closing: When the measured voltage is between V1 and V2, the relay closes, and in other cases, the relay opens; P-5: Fixed point monitoring: When the measurement is higher than voltage V1, the relay is closed, and when the voltage is lower than V1, the relay is disconnected; P-6: Fixed point self-locking monitoring: When the measured voltage is higher than V1, the relay will close; always keep closed; Until the power is manually cut off P-7: Fixed point pulse monitoring: When the measured voltage is equal to V1 (which can fluctuate up and down by 0.02V) each time, the relay outputs a jog signal 6: Setting instructions: Power on display shows that the measured voltage has entered standby mode; Press K1 for the first time (takes more than 1 second to be effective to prevent accidental triggering) Screen flashing display: P --1: K2 plus mode, K3 minus mode Press K1 for the second time, the screen flashes and displays 12.50, indicating V1=12.5V. Adjust V1 for K2 and K3. Press K1 for the third time, and the screen flashes and displays 13.50, indicating V2=13.5V. Adjust V2 for K2 and K3. Press K1 for the fourth time, and the display shows that the measured voltage indicates entering standby mode; Press K4 in standby mode to permanently turn off/on the display and switch to low-power mode label:yes
