Module highlights

The time can be adjusted through a potentiometer to meet your needs for most occasions.

Equipped with MicroUSB 5.0V power input, it is very convenient to use.

5-30V ultra wide power supply voltage.

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

Equipped with a relay engagement indicator light.

Strong anti-interference ability, the relay will not malfunction under various interferences, suitable for industrial control.

Module features

1. Working voltage: Wide voltage between 5-30V, with two power supply interfaces: MicroUSB and soldering terminals

2. Working 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.

3. 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 anti-interference ability 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 cannot provide anti-interference effect. After testing, it was found that improving the stability of the triggering end is necessary to resist interference. This module will not cause misoperation of the relay whether it is 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.
