12V NE555 Oscillator Delay Adjustable Timer Relay Switch Module 0-10 Second

Short description One size: 6.8 for CM * 2.1 for CM Second, the main chip: NE555 Third, the operating voltage: 12 V

Four features: 1, tensile power delay relay. Specifically: 12V power supply for relay, relay not immediately absorbed and relay outputs status are: disconnected normally open, normally closed and public driving; Wait until the delay 1-10 s (adjustable), the suction relay and, this for time, the output status relay is: normally open and public driving, normally closed and public disconnected; While uninterruptible power supply module, this state will be maintained. 2, the delay for time is adjustable, (0 to 10 seconds) 4, to increase the potential can increase the delay for time 5, increasing the capacitor C1 can increase the delay for time 6, with input power indicator 7, with relay indicator 8, the AC 220 V / 10A can be controlled on the equipment. (Maximum control of equipment 2000 for W) 9, with free wheel for protection relay. 10, the for time delay formula: for T = 1.1RC. For example: a capacitor resistance 100 uf 100 K for T = 1.1 * 100000 * 0.0001 = 11 seconds

Applications 1, the vehicle delay device is on, to avoid an excess of current when the car on burn-vehicle device. 2, it is necessary to have in order to start the occasion, to avoid multiple devices at the same for time, the starting current is too large appliances that burn.
