พร้อมส่ง-NE555 Timer Switch 0-10 Sec Adjustable Module Time delay relay Module DC 12V Delay Relay Shield ***** รับประกันสินค้า 30 วัน ***** 12 VDC Delay Timer Switch Adjustable 0-10 Sec This 12 VDC Delay Timer Switch Adjustable 0-10sec is one kind of popular switch module. You can use it control any devices on or off. This is a DC12V controlled 1 channel timer relay module. It has a NE555 timer chip on the board. You can adjust delay time(0-10s) by rotating the potentiometer. When this relay get powered it will delay several seconds before relay turn on. Note: recommended power + series with a diode to protect the circuit Features: 1. The relay time delay and power supply is connected.Specific as follows: for 12 v power supply to the relay, relay not immediately and absorption, relay the output status to: normally open and public disconnect, normally closed and public conduction;Wait for delay 1-10 s (adjustable), relay and absorption, at this point, the relay outputs status to: normally open and public conduction, normally closed and public disconnected;As long as the module power continuously, this state will remain. 2. The delay time is adjustable, (0 ~ 10 seconds) 3. Increasing the potentiometer can increase the delay time 4. the capacitor C1 can increase delay time 5. with input power light 6. A relay and indicator lights 7. The relay will delay to close after connecting with the power supply 8. With relay current protection function 9. The delay time formula: T = 1.1 RC.For example: 100 uf capacitance resistance 100 k T = 1.1 * 100000 * 0.0001 = 11 seconds Specification: - 1 channel relay interface board - Module Properties: NE555 chip - Input Voltage: DC12V - Adjustable Time: 0 – 10 sec - Control Voltage: AC 0~250V/ max. 10A, DC 0-30V/max. 10A - Max.
