DROK Digital Voltage Comparator DC 0-100V Voltage Monitor Controller Relay Module Panel Voltmeter with LED Display Charging Discharging Over&Under Voltage Protection
Voltage comparator will be operated with voltage dc 8- 28V (limitation dc 8 - 32V), and with high accuracy of 0.1V
Users can easily set the upper and lower limits of the voltage, and the testing voltage range is 0-100v
The voltage comparator can save the setting parameters automatically, if the power off suddenly, users won't lost the settings
The voltage monitoring controller is multifunctional with voltage measurement, charging monitoring, discharging monitoring, operate within the range, operate outside the range functions
Improved power supply module makes stable performance, it can be used with a wide voltage range; increase the delay function for the closing and off
Measuring range: DC 0.0 - 99.9VLoad capacity: max load capacity of relay's normally open port: DC 0 - 30V / 10A, AC 0 - 250V / 10A; max load capacity of relay's normally closed port: DC 0 - 28V / 10A, AC 0 - 125V / 10AModule functions:Function 1:Voltage measurement: when select this function the relay will not operate, the display shows the current measurement voltage.Function 2:Charging monitoring: when the measured voltage is lower than the lower limit voltage, the relay operates; when the measured voltage is higher than the upper limit voltage, the relay disconnects.Function 3:Discharging monitoring: when the measured voltage is higher than the upper limit voltage, the relay operates; when the measured voltage is lower than the lower limit voltage, the relay disconnects.Function 4:Operate within the range: when the measured voltage is between the upper and lower limits, the relay operates; in other cases, the relay disconnects.Function 5:Operate outside the range: when the measured voltage is lower than the lower limit voltage, or the measured voltage is higher than the upper limit voltage, the relay operates; in other cases, the relay disconnects.Module interfaces:Input interfaces:DC+: power supply positiveDC-: power supply negativeVIN: detecting port of measuring voltageOutput interfaces:NO: relay's normally open interface. It will be hanging before the reply operates; it will short connect to COM after relay operates.COM: relay's common interfaceNC: relay's normally closed interface. It will short connect to COM before the relay operates; it will be hanging after the reply operates.Package includes:1 x Voltage Monitoring Controller.
