NE555 Timer Switch Adjustable Module Time delay relay Module DC 12V Delay relay shield 0~10S
Product introduction：
● Size: 6.8 CM * 2.1 CM
● The main chip: NE555
● Working voltage: DC5V/12V
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)
4, IKncreasing the potentiometer can increase the delay time
5, the capacitor C1 can increase delay time
6, with input power light
7, A relay and indicator lights
8, Controlled ac 220 v / 10 a device.(maximum control equipment 2000 w)
9, Stream with relay protection.
10, The delay time formula: T = 1.1 RC.For example: 100 uf capacitance resistance 100 k T = 1.1 * 100000 * 0.0001 = 11 seconds
Application:
1, The on-board equipment on the time delay, prevent excessive current when the car lighter burned on-board equipment.
2, Need to have order to start the occasion, to prevent multiple devices at the same time starting current is too large burning appliances.
