3 Types Voltage Measurement Relay Module Digital Display Voltage Comparator
Description:
It provide 5 kinds of functions for users to choose, to meet more application needs.
You can set the voltage upper and lower voltage limits.
Measuring range 0-100V DC, measuring accuracy ±0.1V.
You can set the automatic power saving function.
All set parameters can be automatically saved, the setting contents won't be lost when blackout occurs.
Specification:
Working voltage: DC 5V, 12V, 24V (nominal voltage should not exceed ±10%).
Size(L×W×H): Approx. 67×44×20mm/ 2.64×1.73×0.79 inch
Module voltage inputs: a 4-wire interface, all the terminals are the interface.
DC+: DC power positive
DC-: DC power supply negative
V+: measuring voltage positive electrode
V-: measure negative voltage
5 types of function:
1. Voltage measurement: select this function, the relay will not move, the digital display of the current measurement voltage;
2. Charging : When the measured voltage is lower than the lower limit voltage, the relay pulls above the upper limit voltage, the relay is disconnected;
3. Discharge : When the measured voltage is higher than the upper limit voltage, the relay pulls, below the lower limit voltage, the relay is disconnected;
4. Interval within the pull: When the measured voltage between the upper and lower limits, the relay pull, the other case the relay is off;
5. Interval outside the pull: When the measured voltage is lower than the lower limit voltage, or the measured voltage is higher than the upper limit voltage, the relay pull; other circumstances the relay is disconnected.
Package Includes:
1 Piece of DVB01 Digital Display Voltage Measuring Module
