The maximum load capacity of relay normally closed port: DC 0-28V / 10A, AC 0-125V / 10A

Module function:
Function 1: voltage measurement: select this function, the relay will not act, the digital tube displays the current measurement voltage;
Function 2: charge monitoring: when the measured voltage is lower than the preset voltage V1 and V2 in the lower one, the relay pull, the voltage is higher than V1 and V2 in the higher one, the relay disconnect;
Function 3: discharge monitoring: when the measured voltage is higher than the preset voltage V1 and V2 in the higher one, the relay pull, the voltage is lower than T1 and T2 in the lower one, the relay disconnect;
Function 4: within interval pull: when the measured voltage is between V1 and V2, the relay pull, and in other cases, relay disconnect;
Function 5: out of interval pull: when the measured voltage is lower than the preset voltage V1 and V2 in the lower one, or the measured voltage is higher than the preset voltage V1 and V2 in the higher one, relay both pull, and in other cases, relay disconnect;

Warm tip: the controller will be based on different functions, automatically determine the default voltage V1 and V2, which is the upper limit voltage, which is the lower limit voltage.

Module interface:
Module voltagel input terminal: there is a 4-wire interface, all interfaces have terminals.
--DC +: DC power supply positive
--DC -: DC power supply negative
--V +: the measured voltage positive
--V - : the measured voltage negative
Relay load output: there is a 3-wire interface, all interfaces have terminals.
-- NO: relay normally open interface, the relay is suspended before pulling, and then shorted to the COM after pulling.
-- COM: relay common interface
-- NC: relay normally closed interface, before the relay pull, it is shorted to the COM, and then suspended after pulling.

Operation instructions:
The user can set other parameters through buttons and display selection mode. After all parameters are set, it can be automatically saved, and the power failure is not lost.
User parameters: 6 parameters can be set, respectively, P0-P5, P0 to P5 to represent the names of 6 parameters, the specific meaning of the parameters is as follows:
P-0 (function settings): the parameter value is F-01 to F-05, corresponding to function 1 to function 5;
P-1 (V1 voltage setting): the parameter value is 0.0V to 99.9V;
P-2 (V2 voltage setting): the parameter value is 0.0V to 99.9V;
P-3 (voltage correction): the digital tube flashes together to display the current measured voltage value, and the voltage value can be corrected by + or -.
P-4 (absorption time delay T1):0.1-99.9 seconds; continuous T1 time detection of suction conditions, relay will be absorbed;
P-5 (disconnected delay T2):0.1-99.9 sec; continuous T2 time detection of suction conditions, the relay will be broken;
Work model:
When the power is turned on, it enters the working mode, and the digital tube displays the current measured voltage.
-- Short press [SET], show out, but the program runs normally, in a click to restore display; after extinguishing display, the module will no longer identify the other 3 keys;
-- Long press [SWI], the whole digital tube will flash 2 times, said in a power saving mode to enter power-saving mode, if no operation of any key within 10 seconds, the digital display will be closed, but the normal running of the program, through the short press [SET] key to temporarily restore display, can also be hung in the digital restoration after the show, and then press the [SWI] button to exit the automatic power saving mode, the whole digital tube flashing 3 times, said set successfully;
-- Long press [SET] into [set mode];
Setting mode:
In the working mode, press [SET] key to enter the setting mode parameter name (P0 to P5) to select the interface, then all the functions will stop running. After exit the setting mode, the module will start to run the selected function immediately.
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 [SWI] to switch among the 6 parameters P-0 to P-5) Press [SET] key to enter P0 parameter setting interface. At this time, you can see the specific value of this parameter (LED flashes), then press [SET] to return to the parameter selection interface.
-- Short press [SET] to enter the parameter setting interface;
-- Short press [SWI], parameter selection, you can choose among 6 parameter names "P-0" to "P-5"
-- Long press [SET], save the parameters, exit [setting mode], at the same time enter [work mode];
Parameter setting interface: When Nixie tube displays 6 parameters of P-0 to P-5, press [SET] to enter the corresponding parameter setting interface. At this moment, there will be a digital flashing indicating that this digit can be modified. Press [SWI key to switch flashing digital tube position.
-- Short press [SWI] to switch the flashing digital tube
-- Short press [+] flashing digital tube value plus 1, add to 9 to stop;
-- Short press [-] flashing digital tube value minus 1, reduced to 0 stop;
-- Short press [SET] to return to the parameter selection interface;
-- Long press [SET], save the parameters, exit [setting mode], at the same time enter [working mode]
