NE555 Delay Relay Module 12V

Product Information:

● Size: 6.8CM * 2.1CM

● Main chip: NE555

● Operating voltage: DC 12 V

Product Features:

1. Connect the power relay for delayed engagement. Specifically, after supplying a 12V power supply to the relay, the relay will not draw and the output terminal of the relay will be in the following states: normally open and common disconnected, normally closed and common conductive; After a delay of 1-10 seconds (adjustable), the relay will activate. At this time, the output terminal of the relay will be in the following states: normally open and common conduction, normally closed and common disconnection; As long as the module is continuously powered on, this state will remain constant.

2. Adjustable delay time (0-10 seconds)

4. The delay time can be increased by adding Potentiometer

5. Increasing the capacitance C1 can increase the delay time

6. With input power indicator light

7. With relay closing indicator light

8. Can control equipment below 220V/10A AC. (Large control equipment 2000W)

9. Equipped with relay continuous current protection.

10. Delay time formula: T=1.1RC. For example, capacitance 100uf, resistance 100K, T=1.1 * 100000 * 0.0001=11 seconds

Applicable Occasions:

1. Delayed connection of on-board equipment, causing excessive current to burn out the on-board equipment during car ignition.

2. In situations where sequential starting is required, multiple devices starting at the same time may burn out electrical appliances due to excessive current.
