SKU: 5051 Parsts No. : Package: Brand: Quantity: 1 Function 1 : the setting voltage reference input of a voltage and on the module (reference voltage can be set through the adjustable resistor) the contrast, when the input voltage is greater than the reference voltage, the relay is closed, when the input voltage is less than the reference voltage, relay. Function 2: two input voltage signal respectively to compare 10 and 12, when the voltage signal is greater than the 12 voltage signal 10, the relay is closed, when the voltage signal is 12 less than the voltage signal 10, relay. Three features: the setting voltage reference input of a voltage and on the module (reference voltage can be set through the adjustable resistor) the contrast, when the input voltage is less than the reference voltage, the relay is closed (6-5 closed, 7-6 disconnected); when the input voltage is less than the reference voltage, relay. (a contrary to function) Reference voltage input voltage through precision resistor divider to obtain the reference voltage module, input voltage value determines the range of the reference voltage value, included in the input voltage is 12V, then the reference voltage adjustable range is 0-12V Module purpose: automobile current modification circuit, industrial equipment, laboratory testing, application testing circuit. Working voltage: DC5V/DC12V/DC24V DC Working current: 30mA Pin description: 1. The positive 2. The power input power input cathode 3. control the lamp, when the relay is off (6-5 conduction) lights, relay disconnect (7-6 conduction) when the lights went out. 4. Jump cap sub JP1, relay public call and power input voltage consistent jump cap (1 and 6 connected) disconnect JP1, relay public Angle is not charged (the default) 5. The normally open relay feet 6. Public Angle 7. Relay relay normally closed foot 8. 2 jumper setting function, when to use function need to disconnect the jump line 9. Adjustable resistance, adjust the reference voltage, voltage reference value can be 10 feet in a test run 10. The inverting input end of the comparator (-) 11. Negative 12. The comparator is the positive phase of the input (+) Function description Step 1, the 1 and the 2 input working power supply, adjust the ninth reference voltage is obtained by testing the value tenth Step 2, the input voltage to be compared from twelfth, to be connected with 11 negative voltage comparison Results: if the twelfth voltage is higher than a preset reference voltage (tenth), then the lights, relay, 6-5 conduction, 7-6 disconnection; If the twelfth reference voltage voltage is less than the set (tenth), then the light does not shine, holding relay 7-6 through For more quantity, please contact me.(My skype: ada-yu2013) The Standard shipping we provide is non-regiested mail without a tracking.
