Description:
It is a voltage monitor module.It can control the charging and discharging of the battery by setting the Upper Limit Aoltage Value and the Lower Limit Aoltage Value.
Notice:
It can only be used to detect pure DC signals, Can not used to detect AC voltage or pulsating DC voltage (An unfiltered dc signal).
Parameters:
Product Name:
Voltage Monitor Module
Input Voltage:
DC 12V
Measurement Voltage Range:
0V~99.9V
Working Temperature:
-10℃~65℃
Work Humidity:
5%~95%RH
Board Size:
56mm x 43.7mm x 19mm
Parameter Setting Instructions:
1>
When the module is powered on,the display shows the voltage on the side,and the module enters the standby state.
2>
First set two basic parameters,the Upper Limit Aoltage Value V1 and the Lower Limit Aoltage Value V2.
3>
Short press the SET Button,the display shows "F1" and flashes.
4>
Short press the SET Button a second time to display the default V1 value XX.X blinks. Press the "+" Button or the "-" Button to adjust the Lower Limit Aoltage Value V1.
5>
Short press the SET Button for the third time to display the default V2 value "XX.X" flashes. Press the "+" button or the "-" button to adjust the Upper Limit Aoltage Value V2. (At this time, if V1 is greater than V2,the display will show "ERR".At this time,the parameters need to be changed.It is normal for V1 to be less than V2.)
6>
Press the SET Button for the fourth time. The parameters are permanently saved and exited.
7>
In the standby state,long press the "-" button for three seconds to turn off the display.Long press for another three seconds to turn on the display,designed to reduce power consumption.
Function:
1>
Charge Monitoring: When the measured voltage is lower than the voltage V1,the relay is turned ON, and when the voltage is higher than V2,the relay is turned OFF.
2>
Discharge Monitoring: When the measured voltage is higher than the voltage V2,the relay is turned ON, and when the voltage is lower than V1,the relay is turned OFF.
3>
Pull-in outside the interval: When the measured voltage is between V1 and V2,the relay turned OFF. In other states, the relay is turned ON.
4>
Suction in the interval: When the measured voltage is between V1 and V2,the relay is turned ON. In other states, the relay is turned OFF.
5>
Fixed-point monitoring: When the measured voltage is higher than V1, the relay is turned ON, and lower than V1, the relay is turned OFF.
6>
Fixed-point self-locking monitoring: When the measured voltage is higher than the V1 relay pull-in, always keep the pull-in until the power is cut off manually.
7>
Fixed-point pulse monitoring: When the measured voltage is equal to V1, the relay outputs a jog signal.
