NE555 delay monostable switch module

One size: 6.8cm * 2.1cm

Second, the main chip: NE555

Third, the working voltage: 12V

Four characteristics:

1, power relay delay pull. Specific: 12v power to the relay, the relay will not be sucked directly and status relay outputs are: normally open not connected public, normally closed and public conduction; wait for the delay 1-10s (adjustable), the relay suction and, this time, the relay output state is: normally open and public conduction, normally closed and public disconnected; as long as the uninterruptible power module remains in this state.

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

4, increasing the potential can increase the delay time

5, increasing the capacitor C1 can increase the delay time

6, with input power indicator

7, with relay indicator

8, can control AC 220V / 10A across equipment. (Maximum control equipment 2000W)

9, with overrunning protection relay.

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