0-100V voltage detection relay, DC 12V power supply, 12A charge and discharge voltage For arduino development board

product description

Detection voltage range: 0-99.9V

Maximum relay contact current: 12A (please leave a margin for use)

1: F-1 charge monitoring: when the measured voltage is lower than the voltage, the V1 relay is closed, and the voltage is higher than V2, the relay is disconnected

2: F-2: Discharge monitoring: When the measured voltage is higher than the voltage V2, the relay is closed, and the voltage is lower than V1, the relay is disconnected

3: F-3: pull-in outside the interval: when the measurement voltage is introduced, the relay is disconnected between V1 and V2, and the relay is closed in other states

4: F-4: pull-in in the interval: when the measured voltage is introduced between V1 and V2, the relay pulls in and the relay is disconnected in other states

5: F-5: Fixed-point monitoring: when the measured voltage is higher than V1, the relay is closed, and lower than V1, the relay is disconnected

6: F-6: Fixed-point self-locking monitoring: when the measured voltage is higher than V1, the relay will always be closed until the power is manually turned off

7: F-7: Fixed-point pulse monitoring: When the measured voltage is equal to V1 (0.1V up and down) each time, the relay outputs a jog signal

8: F-8: New function, voltage error correction, range ±5.0V.

*****Supplementary description of setting method:

*After F-1 is set, the parameters of other functions are all the parameters set by F-1.

*After pressing the setting key, F-1 flashes, and then pressing + or-to adjust the function number. After adjusting to a certain function number, press the setting key.

*After pressing the setting key, F-1 flashes, and then pressing + or-to adjust the function number. After adjusting to a certain function number, press the setting key.

Features

Parameter setting description:

Power on, display voltage and enter standby state

First set two basic parameters, the lower limit voltage V1 and the upper limit voltage V2

1: Press the setting key once to display “F1” flashing

2: Press the setting button for the second time to display the default V1 value XX.X flashes, press the “plus” button or the “minus” button to adjust the lower limit parameter V1

3: Press the setting button for the third time to display the default V2 value “XX.X” flashing, press the “plus” button or the “minus” button to adjust the upper limit parameter V2 (at this time if the V1 participating parameter is greater than V2, it will display. “ERR” error prompt , Need to change the parameters, be sure to keep V1 less than V2 as normal)

4: Press the SET key for the fourth time, the parameters will remain permanently and exit

5: In standby mode, press the “minus” button for three seconds to turn off the display, and press it for three seconds to turn on the display. Designed to reduce power consumption
