ماژول تایمر 12 ولت با NE555 و خروجی رله

NE555 0-10 Sec Delay Timer Relay Switch Adjustable
The adjustable Delay timer switch 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. It can also be used in making hobby projects. And is also Compatible with ARDUINO, RASPBERRY PI, AVR, PIC, 8051, etc
The relay time delay and power supply is connected: for 12V 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.
When no power applied the module, the state of the module is “NO” [ normal open ], CB, and COM are conductive. CK and COM are unconducive
When power is switched on, delay for 0-10s, then the module will in the state of “NC” [ normal closed ], CB and COM are unconducive, CK and COM is conductive
The delay time formula: T = 1.1 RC.For example: 100 uf capacitance resistance 100 kT = 1.1 * 100000 * 0.0001 = 11 seconds
