NE555 12V Automotive Electrical time delay Relay Module monostable Timing Relay Timer Control Switch Car Relays Using Pulse Generation Duty Cycle

Power relay delay pull. Specifically: 12v power supply to the relay, the relay will not immediately suck 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 : with a 100K resistor and 100uf capacitor; T (Delay Time) = 1.1 x 100000 x 0.0001 = 11 seconds.
The PCB color and relay make may vary based on availability

Applications:

• The delay of the onboard equipment is turned on to prevent the current from being too large to burn the vehicle equipment when the vehicle is on fire.

• It is necessary to have a sequence to start, to prevent multiple devices from simultaneously starting the current and burning the appliance too much.

Specification:

• Module-based on: NE555 chip; The delay time is adjustable (0~10 seconds) using the in-built potentiometer

• Delay module: Delay connect module

• Input voltage: DC12V

• Control voltage : AC 0 - 250V/max. 10A, DC 0 - 30V/max. 10A

• The operating voltage: 12V DC; Max. load : 2200W
