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 Uninterrupted power module, this state will remain.
The delay time formula : T = 1.1RC. For example : a resistor capacitor 100uf 100K T = 1.1 x 100000 x 0.0001 = 11 seconds.

The colors deviation might differ due to different monitor settings.
