Description: Multifunctional voltage comparator controller, which adopts the industrial as the main control unit--wide measuring range and high accuracy. Functions:Voltage measurement;Charge ;Discharge .And can customize and add other functions according to the needs of the users. The module is made of of high quality, stable performance, can be widely used in a variety of voltage measure&control occasions. Functional characteristics: Provides 5 functions for users to choose;Users can set the upper limit and the lower limit voltage;Measuring range: DC 0-100 V, measuring accuracy +/- 0.1 V;Automatic power saving function;All can be saved automatically. 0-99.9 seconds delay sunction and 0-99.9 seconds delay disconnection. When the voltage is between the upper limit and lower limit, the relay is switched on and the other relay is off.When the measuring voltage is lower than the lower limit voltage, or the measuring voltage is higher than the upper limit voltage, the relay is attracted. Specification: Material: Size(LxWxH): Approx. 67x44x20mm / 2.64x1.73x0.79 inch Working voltage: DC 24V(should not exceed the nominal voltage of +/-10%) Working current: less than 50mA (when the relay is not less than 12mA, turn off display less than 3mA) Working temperature: recommend -20 Celsius - 60 Celsius (limits -30 Celsius - 70 Celsius) Measuring range: 0-99.9V Normally open port maximum load capacity: DC 0-30V/10A, AC 0-250V/10A Normally maximum load capacity: DC 0-28V/10A, AC 0-125V/10A Package Includes: 1 Piece Digital Display Voltage Comparator Module Note: Please allow a slight difference between the size from the above and the actual item due to manual measurement.
