Features:

• Size: 6.8cm x 2.1cm
• Main chip: NE555
• Working voltage: dc 12V
• The relay time delay when power on. 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
• 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

Applications:

• The on-board equipment on the time delay, prevent excessive current when the car lighter burned on-board equipment.
• Need to have order to start the occasion, to prevent multiple devices at the same time starting current is too large burning appliances.

What is in the box:

• 5pcs delay modules
