Wide voltage 5V-30V trigger delay relay module timer delay conduction delay switch K7

Wide voltage 5V-30V trigger delay relay module timer module delay conduction switch

Product description:
The time can be adjusted by the potentiometer to meet your use in most occasions.
With MicroUSB 5.0V power input, it is very convenient to use.
5--30V ultra-wide power supply voltage.
Two trigger modes: external trigger and onboard button.
With relay pull-in indicator.
Strong anti-interference ability, the relay will not malfunction under various interferences, suitable for industrial control.

Module features:
1. Working voltage: any voltage between 5-30V wide voltage, MicroUSB and welding terminal two power supply interfaces
2. Working mode: After power is supplied to the module, the state of the module output terminal is: normally open (NO) and common terminal (COM) are disconnected, normally closed (NC) and common terminal (COM) are connected.
Give a low pulse signal at the external trigger terminal (TRIG), or touch the trigger button momentarily, the relay absorbs and the working indicator lights, at this time, the state of the relay output terminal is: normally open (NO) and the common terminal (COM) are connected, Normally closed (NC) is disconnected from the common terminal (COM). After 0-24 seconds (this time can be adjusted according to your needs), the relay is disconnected. At this time, the relay returns to the state before the trigger.
3. The time can be adjusted by the potentiometer, the default is 0-24 seconds. If you need a longer time, you can replace the larger capacitor (C2) or potentiometer yourself. Delay time formula: T = 1.1RC. For example: capacitance 22uf resistance 1M, then T=1.1*0.000022*1000000=24.2 seconds.
4. With relay pull-in indicator light.
5. The module can be controlled: 10A 250VAC (AC), 10A 30VDC (DC) load.
6. With relay freewheel protection.
7. The signal end of the module is designed with a 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 play an anti-interference role. After testing, it is found that the stability of the trigger end can be improved to resist interference. No matter the electromagnetic interference environment or the moment when the module is turned on and off, the relay will not produce a malfunction.
8. Size: 5.4*1.9*1.8cm (length*width*height)
