NE555 Timer Switch Adjustable Delay Module 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)
• IKncreasing the potentiometer can increase the delay time
• The capacitor C1 can increase delay time
• With input power light
• A relay and indicator light
• 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

Package Includes:

• 1 x NE555 Timer Switch Adjustable Delay Module
