DC 9V 12V 24V Voltage Detection Relay Module Circuit Monitoring Module Overvoltage Protection Discharge Monitoring Board

Note: Some customers reported that the detection is unstable, and the result found that the customer detected the AC voltage, do not use it to detect the AC voltage, there will be instability or even burn out the board, pulsating DC is also easy to fluctuate (direct rectified DC signal without filtering) To detect pure DC signals, remember! Otherwise bear the consequences!

Product Features:

Powerful, detection range from DC 0-99.9V, minimum 0.1V adjustment
Charging protection, discharge protection
Overvoltage protection, undervoltage protection
Fixed-point pulse, stable performance
Charge and discharge control, a variety of supply voltages are selectable 9V/12V/24V

Product parameters:

Detection voltage range: 0-99.9V (minimum 0.1V onset)
Working voltage: DC 9V/12V/24V optional
Maximum current of relay contact: 12A (please leave a margin for use)
Product size: 56mm*44mm

Operation introduction:

1. In the non-setting state, press the SET key shortly, cyclic display: working mode - lower >limit voltage - > upper limit voltage.
2. In the non-setting state, Changan SET key for 2 seconds to enter the parameter setting state; The display displays F01, press the +- key to select the parameters to set, F01 (upper voltage), F02 (lower voltage), F03 operating mode, F04 voltage calibration value.
3. After selecting the parameters that need to be set, press the SET key to enter the parameter setting state, press the +- key to adjust, when the lower limit voltage is greater than or equal to the upper limit voltage, the display displays 1 second of Err, prompting the user. When the lower limit voltage is equal to the upper limit voltage, turn off the relay output function.
4. After setting the parameter value, press the SET key to return to the parameter list.
5. After the parameters are set, press and hold SETs for 2 seconds to exit and save the parameters.
6. In the non-setting state, press and hold SET and + keys at the same time for 2 seconds to restore factory settings.
7 Long press - Turn off or on the digital tube to display the energy-saving mode

Setup details:

F03 Operating Mode Non-set state
Long press SET to select F03 working mode selection, + and - to select the desired function after long press SET to save and exit
It should be noted that before setting this parameter, please set the upper and lower voltage as needed
H-1, charging monitoring when the monitoring voltage is lower than the lower limit voltage relay sucked in, above the upper limit voltage disconnected.
H-2, discharge monitoring when the monitoring voltage is above the upper limit voltage relay draws, below the lower limit voltage disconnects.
H-3 interval external suction When the monitoring voltage is between the upper limit voltage and the lower limit voltage, the relay is disconnected, and the other state relays are closed
H-4 interval suction When the monitoring voltage is between the upper limit voltage and the lower limit voltage, the relay is closed, and the other state relays are disconnected
H-5 Fixed-point monitoring When the monitoring voltage is above the lower limit voltage relay is closed, the lower limit voltage relay is disconnected
H-6 Fixed-point self-locking monitoring When the monitoring voltage is higher than the lower limit voltage relay is closed, it is always retained until manual intervention or power off
H-7 Fixed-point pulse monitoring When monitoring each time equal to the lower limit voltage (ﾱ0.1V), the relay outputs a jog signal
F04 Correction Mode Long press the SET key to enter the non-set state, +-select
The default is 0 error, if you need to set the adjustment as needed,
For example, the actual input voltage is 12.5V, and the module displays 12.4V, at this time, the error can be set to 0.1V, that is, 12.4+0.1=12.5
For example, the actual input voltage is 12.5V, and the module displays 12.6V, at this time, the error can be set to -0.1V, that is, 12.6-0.1=12.5
