NE555 DK555 Timer Switch - 5Pcs Adjustable Disconnect Time Delay Relay Module compatible with DC 12V

NE555 DK555 Timer Switch - 5Pcs Adjustable Disconnect Time Delay Relay Module for DC 12V 5Pcs NE555 DK555 Timer Switch Adjustable Disconnect Module Time Delay Relay Module DC 12V Delay Rel The relay time delay and supply is connected.Specific as follows: for 12 v 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 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 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 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 burning appliances.
