Brief description

One size: 6.8CM * 2.1CM

Second, the main chip: NE555

Third, the working voltage: 5V/12v

1. Power relay delay pull. Specifically: 12v power supply to the relay, the relay will not immediately sucked and status relay outputs are: normally open disconnected public, normally closed and public conduction; wait until the delay 1-10s (adjustable), the relay suction and, this time, the relay output status is: normally open and public conduction, normally closed and public disconnected; as long as uninterruptible power module, this state will remain.

2. The delay time is adjustable, (0 to 10 seconds)

3. Increasing the potential can increase the delay time

4. Increasing the capacitor C1 can increase the delay time

5. With input power indicator

6. With relay indicator

7. Can control AC 220V / 10A about equipment. (Maximum control equipment 2000W)

8. With freewheeling protection relay.

9. The delay time formula: T = 1.1RC. For example: a resistor capacitor 100uf 100K T = 1.1 * 100000 * 0.0001 = 11 seconds

Applications:

1. The delay-vehicle device is turned on, to prevent excessive current when the car ignition burn-vehicle device.

2. You need to have in order to start the occasion, to prevent multiple devices simultaneously starting current is too large burning appliances.
