Digital Timer Delay Relay Module Trigger Switch Micro USB 5V-30V

Digital Timer Delay Relay Module Trigger Switch Micro USB 5V-30V

Cara Kerja:

Saat diberi tegangan, relay belum bekerja dan harus diberi sinyal / trigger (pencet saklar/switch) baru relay bekerja dan ada delay untuk relay kembali mati (waktu ini yang bisa diatur via VR)

Module features:

1. Working voltage: any voltage between wide voltage 5--30V , MicroUSB and welding terminal two power supply interfaces

2. Working mode: After supplying power to the module, the status of the output terminal of the module is: normally open (NO) is disconnected from the common terminal (COM), and normally closed (NC) is connected to the common terminal (COM).

Give a low pulse signal at the external trigger terminal (TRIG), or at the moment when the trigger button is touched, the relay is activated and the working indicator light is on. At this time, the status of the relay output terminal is: normally open (NO) and common terminal (COM) are connected. Normally closed (NC) and common (COM) are disconnected. After 0-24 seconds (this time can be adjusted according to your needs), the relay is disconnected, and the relay returns to the state before triggering.  

3 . Time can be adjusted by a potentiometer, the default 0-24 seconds. If it takes longer, you can replace the larger capacitor (C2) or potentiometer yourself. Delay time formula: T=1.1RC. For example: capacitor 22uf and resistance 1M, then T=1.1*0.000022*1000000=24.2 seconds.            

4. With a relay pull-in indicator light.

5. The module can be controlled: 10A 250VAC (AC), 10A 30VDC (DC) or less load.

6. With relay freewheeling protection.

7. The signal end of the module is designed with pull-up and filter circuit, which has strong anti-interference ability and is suitable for industrial control. Many manufacturers have added optocouplers for isolation, but the module is not isolated from the ground of the trigger signal, which does not have the effect of anti-interference. After the test, it is found that the stability of the trigger terminal can be improved to resist interference. The relay will not malfunction regardless of whether it is in an electromagnetic interference environment or the moment the module is powered on or off.

8. Size: 5.4*1.9*1.8cm (length*width*height)

9. Weight: 16g 

Applications:

1. Anti-theft alarm delay, building sound and light control light switch, etc.

2. Delayed connection of on-board equipment to prevent excessive current from burning the on-board equipment when the car is on fire.

3. Where there is a need for sequential start, to prevent multiple devices from starting at the same time and the current is too large to burn the electrical appliances.
