12V Delay Relay Module, Automobile Start Delay Switch With Optocoupler, Signal Trigger, Adjustable Time
Description
Working principle: This module is a delay module triggered by an external signal.
Specifically: 1)--to->2)--to->3)--to->4).

1) Supply power to the module (12v or 5V), and the relay will be closed immediately (at this time, the status of the module output terminal is: normally open and public conduction, normally closed and public disconnection)

2) The relay is disconnected after a delay of 0-25 seconds (the output status of the module at this time is: normally open and public disconnection, normally closed and public conduction)

3) Keep disconnecting until it is triggered by an external trigger signal, and the relay is closed again

4) After a successful trigger, the relay will be disconnected after a delay of 0-25 seconds. Note: If the trigger signal is always on, the module will be closed until the trigger signal disappears, and the module will start to delay timing. The delay is 0-25 seconds. open. (At this time, the relay returns to the state before triggering normally open and public disconnection, normally closed and public conduction).



In addition: (The trigger signal of this module can be provided by a separate power supply system and the power supply of the module may not be a power supply system. At the same time, the trigger level can be a high-level pulse or a low-level pulse, which has strong versatility.)

Module features:

1. Length*Width=52mm*16mm

2. The working voltage of the module is 12V

3. The module can be controlled: 10A 250VAC (AC), 10A 30VDC (DC) or less load.
4. The time can be adjusted by the potentiometer. The default is 0-25 seconds. It takes longer. You can replace a larger capacitor or potentiometer by yourself. You can also contact customer service before shipping. We will change it for you and ship it.
5. Delay time formula: T=1.1RC. For example: capacitance 47uf resistance 500K T=1.1*500000*0.000047=25.85 seconds.
6. The power supply of the module is equipped with a diode to prevent reverse connection of the power supply, so friends can rest assured to connect.
7. The signal end of the module is designed with optocoupler isolation, which has strong anti-interference ability, can adapt to the application of high and low level control signals, and is suitable for industrial control.
8. The module can be triggered repeatedly (for example, if you set a delay of 10S, if a trigger action occurs again within a 10S delay of a trigger, the 10S delay will be repeated when the action occurs again, that is, it will be triggered once after the ZUI within the undelayed period. Whichever is higher, delay 10S later, until the delay time reaches to complete the whole process of one trigger delay. After the delay is over, trigger again and delay again

9. No power consumption in standby (Almost power consumption in standby, zero current, greatly extending the life of the car battery. Green product)

Product application: It can be used for robots, car light delay, intelligent product development, automation equipment, PLC development, smart home, anti-theft alarm delay, electronic development, etc.
