Brief description] One size: 6.8CM * 2.1CM Second, the main chip: NE555 Third, the working voltage: 12V  Four characteristics: 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) 4, increasing the potential can increase the delay ti
