Product Details

12V Delay-off Relay Module
Module size: 65*20mm
Main chip: NE555
Working voltage: DC 12V
1, turn on the power relay immediately suction, and then a delay of 1-10S disconnection
Specifically: supply 12v power to the relay, the relay immediately suction and.
The state of the relay output is: normally open and public conductive, normally closed and public
The state of the relay output is: normally open and common conductive, normally closed and common disconnect;
At this time, the state of the relay output is: normally open and public disconnect, normally closed and public conductive; as long as the module is constantly on, the relay output is normally open and public disconnect.
As long as the module is not powered on, this state will be maintained.
2、Delay time is adjustable, (0-10 seconds)
3、Increase the potentiometer can increase the delay time.
4、Increase capacitance C1 can increase the delay time.
5、Input power indicator
6、With the relay suction indicator
7, can control AC 220V/10A a device. (Control equipment 2000W (peak))
8, with relay current protection.
9, delay time formula: T = 1.1RC. eg: capacitance 100uf resistance 100K
T = 1.1 * 100000 * 0.0001 = 11 secondsTranslated with DeepL.com (free version)
