Function two: 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 The first step, the 1 and the 2 input working power supply, adjust the ninth reference voltage is obtained by testing the value tenth The second step, 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 Wholesale to save you more money! 10pcs Perfect 5V Relay SIP-1A05 Reed Switch Relay for PAN CHANG Relay 4PIN 4PCS 1/8"Plastic Electric Air Gas Water Solenoid Valve Normally Closed 12V DC 5pcs NE555 Square Wave Duty Cycle and Frequency Adjustable Module 5PCS NEW 3W White COB High Power LED Stripe LED Light Emitting Diode 10pcs 4010S 40mm x40mm x10mm Brushless DC Cooling Fan Perfect 10pcs MAX7219 Dot Matrix Module Control Display Module Cascade DIY kit Perfect 4pcs Liquid Level Controller Sensor Module Water Level Detection Sensor Perfect 2PCS NEW 30W 5730 Pure White LED Light Emitting Diode SMD 220V 85mm Perfect HOT Category On sale _Wholesale_ __Combination__ ___Sensors_ _ICs & Processors_ _Arduino_ Cables & Connectors_ LCD Modules_ Power Modules _Switches_ _ Electrical Connectors_ Valves__ __ Car Fuse__ Wireless Modules Wireless Bluetooth Relay Modules Breadboards _PCB Boards____ __LED____ ____DIYs___ ___ Resistors _ SHIPPING PAYMENT RETURNS FEEDBACK ABOUT US Address: Please make sure your Paypal address is updated and accurate.
