รีเลย์ หน่วงเวลา เปิด 12V Time Delay Relay Module 1-25 วินาที Fixed DC 12V (PCB เขียว)

Working principle: This module is an external signal trigger delay module. 

1) Power the module (12v or 5V), the relay will immediately pull in (the state of the module output is: normally open and common conduction, normally closed and public disconnect)

2) After 0-25 seconds delay, the relay is disconnected (the module output status is: normally open and public disconnect, normally closed and common conduction)

3) Always keep disconnecting until the external trigger signal is triggered, the relay pulls in again

4) After the successful trigger, delay the delay again after 0-25 seconds.  Note: If the trigger signal is always there, it will always pull in, until the trigger signal disappears, the module starts delay timer, delay 0~25 seconds open. (At this point, the relay returns to the pre-trigger state normally open and public disconnect, normally closed and common conduction). 

Another: (The trigger signal of this module can be provided by a separate power system and the power supply of the module can not be a power system, and the trigger level can be a high level pulse or a low level pulse, which is highly versatile)

Module features:

1. ยาว x กว้าง = 52mm x 16mm
2. Working voltage: 12V
3. the module can be controlled: 10A 250VAC (AC), 10A 30VDC (DC) below the load. 
4. the time can be adjusted by the potentiometer default 0 - 25 seconds, take longer, you can replace the larger capacitor or potentiometer. 
5. Delay time formula: T = 1.1 x R x C. For example: Capacitor 47uf and resistance 500K, T = 1.1 x 500000 x 0.00047 = 25.85 seconds.
6. the module power supply has anti-power reverse diode , friends can rest assured that wiring. 
7. The signal terminal of the module is designed with optocoupler isolation , strong anti-interference ability, and can adapt to the application of high and low level two control signals, suitable for industrial control.
8. The module can be repeatedly triggered (for example, setting the delay time 10S, and triggering action again within a certain trigger 10S delay time, then re-10S delay when the action occurs again, that is, the last trigger within the end of the undelayed time is Pre-delay, delay 10S backwards until the delay time reaches the completion of a trigger delay. After this delay is over, trigger again and delay again.
9. standby no power consumption ( standby almost power consumption, zero current, greatly extend the life of car batteries. Green products)

Product application:
robots, car light delay, intelligent product development, automation equipment, PLC development, smart home , anti-theft alarm delay , electronic development and so on.

The product is detailed as follows:

  

 Common wiring diagram:

Can be used for: car reading lights, parking sensors, reversing cameras, etc.

Function of the module: When the reversing signal comes, the reversing radar is turned on, and the time T can be delayed, waiting for the end of the reversing, and the radar reversing power is turned off.
