Features 1.Provide 5 functions for users to choose, to meet more application needs 2.The user can set the voltage upper limit and voltage lower limit 3.Measuring range DC 0-100V, measuring accuracy + 0.1V 4.Increase the pull in delay and disconnect delay function 5.All settings parameters can be automatically saved, the content of power loss is not lost Specification DVB01 module is a multi-function voltage monitoring controller, using industrial-grade micro-controller as the main control unit, measuring a wide range of high precision. The controller prefers 5 different functions, and can customize and add other specific functions according to user's requirements. The user can set the voltage upper limit and the voltage lower limit. The module is made of genuine high-quality components carefully processed, stable performance, can be widely used in a variety of voltage measurement and control applications. Features: 1. Provide 5 functions for users to choose, to meet more application needs 2.The user can set the voltage upper limit and voltage lower limit 3. Measuring range DC 0-100V, measuring accuracy + 0.1V 5. Increase the pull in delay and disconnect delay function 6. All settings parameters can be automatically saved, the content of power loss is not lost 7.New 0-99.9 seconds delay pull-IN and 0-99.9 seconds delay the pull-off function Module function: Function 1: Voltage measurement: select this function, the relay will not act, digital display current measuring voltage; Function 2: Charging monitoring: when the measurement voltage is lower than the lower limit voltage, the relay is pulled in, higher than the upper limit voltage, the relay is disconnected; Function 3: Discharge monitoring: when the measurement voltage is higher than the upper limit voltage, the relay is pulled in, lower than the lower limit voltage, the relay is disconnected; Function 4: Pull in interval: when the measuring voltage is between the upper limit and the lower limit, the relay is pulled in, and other conditions are disconnected; Function 5: Out of range pull in: 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 pulled in; otherwise, the relay is disconnected. Warm hint: the controller will automatically judge which is the upper limit voltage and which is the lower limit voltage of the preset voltage V1 and V2 according to different functions Specification: Color: Red Material: plastic Operating voltage: DC12V/24V(optional) (should not exceed the nominal voltage of +/- 10%) Operating current:< 90mA at 5V (less than 12mA when relay is not active, less than 3mA for off display) < 50mA at 12V(less than 12mA when the relay is not activated, turn off the display is less than 3mA) < 35mA at 24V(less than 12mA when the relay is not activated, turn off the display is less than 3mA) Operating temperature: Recommended -20~ 60℃(limit range -30~70℃) Measuring range: 0-99.9V Load capacity: relay normally open port maximum load capacity: DC 0-30V / 10A, AC 0-250V / 10A Relay normally closed port maximum load capacity: DC 0-28V / 10A, AC 0-125V / 10A Module interface: Input end 1, DC +: positive DC power supply 2, DC-: DC power supply anode 3, V +: measuring voltage positive 4, V-: measuring the negative voltage Relay load output: 1, NO: relay normally open interface, the relay pull before the open, after the suction with COM shorted 2, COM: relay common interface 3, NC: normally closed relay interface, the relay before the short circuit with the COM, pull after the vacant Module size: 67*44*20mm/2.6*1.7*0.8in Weight: Approx.30g/1.1oz Package list: 1 x Digital window voltage comparator Note: Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering.
