About HiLetgo NE555 DC 12V Delay Timer Switch Adjustable
Specification: Size: 6.8CM * 2.1CMMain chip: NE555Working voltage: 12 volts DC Characteristics: 1. Connected to the power relay to 1-10s fixed cycle pull and disconnect. Specifically: to the relay for 12v power supply, the relay will immediately suck and relay output status: normally open and common conduction, normally closed and disconnected; until the delay 1-10s (can be adjusted), the release of the relay , At this moment, the state of the relay output is: Normally open and common open, normally closed and common conduct; As long as the module is not powered off, this state will keep and release with fixed cycle of 1-10s.2. Adjustable delay time (0 ~ 10 seconds).3. Increase the potentiometer can increase the delay time. 4. Increase the capacitor C1 can increase the delay time. 5. With input power indicator.6. With relay pull indicator.7. Can control the exchange 220V / 10A about equipment. (Maximum control equipment 2000W). 8. With relay freewheeling protection. 9.Delay time formula: T = 1.1RC. For example: Capacitance 100uf Resistance 100K T = 1.1 * 100000 * 0.0001 = 11 seconds. Package Included:1*NE555 DC 12V Delay Timer Switch Adjustable Module
