Module highlights:
The time can be adjusted by the potentiometer to meet your most occasions.
With MicroUSB 5.0V power input, it is very convenient to use.
5--30V ultra-wide power supply voltage.
There are two trigger modes: external trigger and on-board button.
With a relay pull-in indicator light.
Strong anti-interference ability, the relay will not malfunction under various interferences, suitable for industrial control.
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. The time can be adjusted by the potentiometer, the default is 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, and it is not effective in anti-interference. After testing, it is found that the stability of the trigger terminal must be improved to resist interference. The relay will not malfunction regardless of whether the module 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 starting, to prevent multiple devices from starting at the same time and the electric current is too large to burn the electrical appliances.
