Current: less than 90mA at 5V (less than 12mA when the relay does not operate, and less than 3mA when the relay is turned off)
Less than 50mA at 12V (less than 12mA when the relay does not operate, and less than 3mA when the relay is closed)
Less than 35mA at 24V (less than 12mA when the relay does not operate, and less than 3mA when the relay is closed)
Module voltage input: There are 4-wire interfaces, all interfaces have terminals:
DC+: Positive pole of DC power supply
DC-: negative pole of DC power supply
V+: the positive pole of the measuring voltage
V-: negative pole of measuring voltage
Relay load output: There are 3-wire interfaces, all interfaces have terminals:
NO: The relay is normally open, the relay is suspended before it is closed, and it is shorted to COM after it is closed.
COM: relay common interface
NC: Relay normally closed interface, short-circuit with COM before the relay picks up, and hangs after picking up
Function 1:
Voltage measurement: Select this function, the relay will not act, and the digital tube displays the current measured voltage.
Feature 2:
Charging monitoring: When the measured voltage is lower than the lower limit voltage, the relay is closed, and when it is higher than the upper limit voltage, the relay is disconnected.
Feature 3:
Discharge monitoring: when the measured voltage is higher than the upper limit voltage, the relay is pulled in, and when it is lower than the lower limit voltage, the relay is disconnected.
Feature 4:
Pull-in in the interval: When the measured voltage is between the upper limit and the lower limit, the relay pulls in, otherwise the relay is disconnected.
Feature 5:
Pull-in outside the interval: when the measured voltage is lower than the lower limit voltage, or the measured voltage is higher than the upper limit voltage, the relay pulls in; otherwise, the relay is disconnected.
Tip: The controller will automatically determine which of the preset voltages V1 and V2 is the upper limit voltage and which is the lower limit voltage according to different functions. The user does not need to worry about who is bigger and who is smaller when setting.
Users can select the function mode through the keys and display, and can also set other parameters. After all parameter settings are completed, they can be automatically saved and will not be lost when power off.
User parameters: There are 6 kinds of parameters that can be set, namely P0-P5, P0 to P5 represent the names of the 6 kinds of parameters, and the specific meanings of the parameters are as follows:
P-0 (function setting): parameter value F-01 to F-05, corresponding to function 1 to function 5.
P-1 (V1 voltage setting): parameter value 0.0V to 99.9V.
P-2 (V2 voltage setting): parameter value 0.0V to 99.9V.
P-3 (voltage correction): The nixie tubes flash together to display the current measured voltage value. Press + or - to correct the voltage value.
P-4 (Pick-up delay T1): 0.1-99.9 seconds; the relay will only pick-up when the pickup condition is detected for continuous T1 time.
P-5 (disconnection delay T2): 0.1-99.9 seconds; the relay will not be disconnected until the pull-in condition is detected for continuous T2 time.
The user can select the function mode through the keys and display, and can also set other parameters. After all parameters are set, they can be automatically saved and will not be lost when power is turned off.

1. Working mode:
After the power is turned on, it will enter the working mode, and the digital tube will display the current measured voltage.
1.1 Short press [SET], the display goes out, but the program is running normally, press it to restore the display; after the display goes out, the module will no longer recognize the other 3 keys;
1.2 Press and hold [SWI], the digital tube will flash 2 times as a whole, indicating that it enters the power saving mode. After entering the power saving mode, if no button is operated within 10 seconds, the display of the digital tube will be turned off, but the program is running normally, you can Temporarily restore the display by short pressing the [SET] key, or after the digital hanger restores the display, and then long press the [SWI] key to exit the automatic power saving mode, the digital tube as a whole flashes 3 times, indicating that the setting is successful;
1.3 Press and hold [SET] to enter [Setting Mode];
2. Setting mode:
In the working mode, long press the [SET] key to enter the parameter name (P0 to P5) selection interface of the setting mode, and all functions will stop running at this time; after exiting the setting mode, the module will immediately start running the selected function.
Parameter selection interface: After entering the setting mode, the digital tube will display "P-0", indicating that the currently selected parameter is P0 (short press
¡¼SWI¡½can switch between 6 parameters from P-0 to P-5), press ¡¼SET¡½key to enter the parameter value setting interface of P0. At this time, you can see the specific value of the parameter (the digital tube flashes), and then press [SET] to return to the parameter selection interface.
2.1 Short press ¡¼SET¡½to enter the parameter setting interface;
2.2 Short press [SWI] to select parameters, which can be selected from the 6 parameter names from "P-0" to "P-5";

Parameter setting interface: When the digital tube displays the 6 parameters from P-0 to P-5, enter the corresponding parameter setting interface by short pressing [SET]. At this time, there will be a digital hanging flashing, indicating that the digit can be modified, press ¡¼SWI¡½key can switch the position of the flashing digital tube.
2.4 Short press [SWI] to switch the flashing nixie tubes (ones digit ten hundreds digit switching);
2.5 Short press [+] to add 1 to the flashing digital tube value, and stop when it reaches 9;
