Youmile NE555 Delay Timer Relay 12V DC 0-10 Seconds Adjustable Delay Timer Switch Module with screwdriver for Arduino Automotive Control System Electrical Equipment,pack of 5

• What it does: The NE555 delay relay is used for delaying other electrical appliances by adjusting the delay time of 0-10 seconds, especially for battery-powered control products.
• Material: It is made of electronic accessories, inner conductor is pure copper.It is long lasting and durable for you to use.
• NE555 chip features: Timing from microseconds to long hours, simple circuit design, high pulse generation / timing accuracy, adjustable duty cycle, wide application range, large amount of information.
• Adjustable: The timer switch relay module can be adjustable timer delay(default setting:0-10s) and counter clockwise adjustment of potentiometer to increase delay time.High reliability, strong vibration resistance, good electromechanical performance.
• Applications: The module is perfect for SCM learning, electronic competition, product development, graduation design and so on.

The module adopts high-performance timing CPU design, which is operate fast.It possesses of the power indicator LED and switch trigger timing indication LEDs.The output can be connected to AC 250V 10A and DC 30V 10A,and the max control equipment is up to 2200W.Has a very high cost performance, value for money.Can be used with other circuits to provide a time delay for other appliances.Widely used with various electrical equipment,especially for battery-powered control products. Features: 1. The relay time delay and power supply is connected: 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. Increase the potentiometer can increase the delay time 4. Increase the capacitance C1 can increase the delay time 5. Possess of input power indicator 6. Possess of relay pull-in indicator 7. can control the AC 220V/10A equipment.(Maximum control device 2000W) 8. Possess of relay freewheeling protection 9. Delay time formula: T=1.1RC.For example: Capacitance 100uf resistance 100K T = 1.1 * 100000 * 0.0001 = 11 seconds Specification: Module Properties : NE555 chip Input voltage : DC12V Adjustable time : 0 to 10sec Control voltage : AC 0~250V / max. 10A, DC 0~30V / max. 10A Max. loading : 2200W Module size: 68mm * 21mm*18mm Package Includes: 5 x 12V NE555 Delay Relay Module 1 x Screwdriver
