Connected Plant Sensor -12V Voltage Comparator Module Highlights Generic Brand 12V Voltage Comparator Module Description: Multi-functional voltage comparator controller, which adopts industrial microcontroller as the main control unit - wide measuring range and high precision . Functions: voltage measurement; load monitoring; discharge monitoring.And can customize and add other functions according to user requirements. The module is made of high quality genuine components, stable performance, can be widely used in a variety of voltage measurement and control occasions. Functional characteristics: offers users the possibility to choose 5 functions; users can set upper limit voltage and lower limit voltage; measuring range: DC 0-100V, measuring accuracy +/- 0.1V automatically 0-99.9 seconds delay reaction and 0-99.9 seconds disconnection. When the voltage is between the upper limit and the lower limit, the relay is activated and the other relay is deactivated. When the measurement voltage is lower than the lower limit voltage or the measurement voltage is higher than the upper limit voltage, the relay is energized. Specification: Material: Plastic Size (LxWxH): Approx. 67x44x20mm / 2.64x1.73x0.79inch Working voltage: DC 12V (should not exceed rated voltage +/-10%) Working current: less than 50mA (when the relay is not less than 12mA , turn off the display within 3mA) Operating temperature: recommended -20 Celsius - 60 Celsius (limits -30 Celsius - 70 Celsius) Measurement range: 0-99.9V Normally open port maximum load capacity: DC 0- 30V/10A, AC 0-250V/10A Normally closed port maximum load capacity: DC 0-28V/10A, AC 0-125V/10A Package includes: 1 Piece Digital Display Voltage Comparator Module Note: If there is please allow slight difference between the size of the above and the actual item due to manual measurement.
