5V-30V trigger delay relay module timer module / delay switch

Product Description

5V-30V trigger delay relay module timer module / delay switch

Module characteristics:

1 working voltage: wide voltage 5–30V between any voltage, MicroUSB and welding terminal two kinds of power supply interface

2 work mode: to the module power supply, the module output state is: normally open (NO) and common side (COM) off, normally closed (NC) and common (COM) conduction.

In the external contact (TRIG) to start a low pulse signal, or touch the trigger button instantly, the relay and the indicator light, the relay output state is normally open (NO) and the common end (COM) conduction, normally closed (NC) and the common end (COM) fault open, after 0-24 seconds (this time can be adjusted according to your needs) minutes after the relay is switched off, the relay back to the state before the trigger.

3 time can be adjusted by potentiometer, the default 0-24 seconds. If you need more time, you can replace the larger capacitor (C2) or potentiometer. Time delay formula: T = 1.1RC. For example: the capacitor 22uF resistor T=1.1*0.000022*1000000=24.2 is 1M seconds.

With 4 relay indicator.

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

6 relay protection.

7 module signal terminal design with the pull and filter circuit, strong anti-interference ability, suitable for industrial control. Many manufacturers have added optocoupler isolation, but the module and the trigger signal and no isolation, no interference effect. After the test, it is found that the stability of the trigger end can be improved. The module is not in the moment of the electromagnetic interference environment, or the module power off.

8 dimensions: 5.4*1.9*1.8cm (L * w * h)

9 weight: 16g

Suitable occasion:

1 alarm delay, building sound and light control switches etc..

2 vehicle equipment delay through, burning of large current on-board equipment prevent car ignition.

3 need to be in order to start the occasion, to prevent multiple devices at the same time to start the current too large burning appliances.
