NE555 Timer Switch Adjustable Module Time delay relay Module

NE555 Timer Switch Adjustable Module Time delay relay Module DC 12V Delay relay shield 0~10S

•  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.
•  The delay time is adjustable, (0 ~ 10 seconds)
•  Increasing the potentiometer can increase the delay time
•  the capacitor C1 can increase delay time
•  with input power light
•  A relay and indicator lights
•  Controlled ac 220 v / 10 a device.(maximum control equipment 2000 w)
•  Stream with relay protection.
•  The delay time formula: T = 1.1 RC.For example: 100 uf capacitance resistance 100 k T = 1.1 * 100000 * 0.0001 = 11 seconds
