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

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

Module highlights:

The time can be adjusted through a potentiometer to meet your needs in most situations.

withMicroUSB 5.0VPower input, very convenient to use.

5--30VWide supply voltage.

There are two triggering methods: external triggering and onboard buttons.

Equipped with a relay engagement indicator light.

Strong interference capability, relays will not malfunction under various interferences, suitable for industrial control.

Module features:

oneWorking voltage:wide voltage5--30VBetween any voltage,MicroUSBandWelding terminalsTwo types of power supply interfaces

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

When a low pulse signal is given to the TRIG or the trigger button is lightly touched, the relay will be activated and the working indicator light will be on. At this time, the status of the relay output terminal is: normally open (NO) is conductive to the common terminal (COM), and 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 will disconnect and return to the state before triggering.  

three.The time can be adjusted through a potentiometer, with a default range of 0-24 seconds. If it takes longer, you can replace the larger capacitor (C2) or potentiometer by yourself. Delay time formula: T=1.1RC. For example, if the capacitor is 22uf and the resistor is 1M, then T=1.1 * 0.000022 * 1000000=24.2 seconds.            

4. It has a relay engagement indicator light.

5. The module can control loads below 10A 250VAC (AC) and 10A 30VDC (DC).

6. Equipped with relay continuous current protection.

7. The module signal end is designed with pull-up and filtering circuits, which have strong interference capabilities and are 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 interfere. After testing, it was found that improving the stability of the triggering end is necessary for interference. This module will not cause misoperation of the relay, whether in an electromagnetic interference environment or when the module is powered on or off.

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

9. Weight: 16g 

Applicable occasions:

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

2. Delayed connection of onboard devices to prevent excessive current from burning out the onboard equipment during car ignition.

3. In situations where sequential startup is required, it is necessary to prevent multiple devices from starting at the same time and burning out electrical appliances due to excessive current.
