中文描述：

宽电压5V-30V 触发延时继电器模块  定时器模块 延时导通 延时开关 按键

模块亮点：

时间可通过电位器调节，满足您大多数场合的使用。

带有MicroUSB 5.0V供电输入，使用非常方便。

5--30V超宽的供电电压。

外部触发和板载按键两种触发方式。

具有继电器吸合指示灯。

抗干扰能力强，各种干扰下继电器不会误动作，适合工业控制。

模块特性：

1.工作电压：宽电压5--30V间任意电压，MicroUSB和焊接端子两种供电接口

2.工作模式：给模块供电后，模块输出端的状态为：常开(NO)与公共端(COM）断开，常闭（NC）与公共端（COM）导通。

在外接触发端（TRIG）给一个低脉冲信号，或者轻触触发按键瞬间，继电器吸和，工作指示灯亮，此时，继电器输出端的状态为：常开(NO)与公共端(COM）导通，常闭（NC）与公共端（COM）断开，经过0-24秒（此时间可根据您的需求自行调节）钟后继电器断开，此时继电器又回到触发前的状态。  

3.时间可通过电位器调节，默认0-24秒。如果需要更长时间，可自行更换更大电容(C2)或电位器。延时时间公式：T＝1.1RC。例如：电容22uf电阻1M  则T=1.1*0.000022*1000000=24.2秒。            

4.具有继电器吸合指示灯。

5.模块可控制：10A 250VAC（交流），10A 30VDC（直流）以下负载。

6.具有继电器续流保护。

7.模块信号端设计有上拉及滤波电路，抗干扰能力强，适合工业控制。很多厂家都加了光耦进行隔离，但是模块与触发信号的地并没有隔离，起不到抗干扰作用的。经过试验后发现还是提高触发端的稳定性才能抗干扰，本模块不管是在电磁干扰环境下，还是模块通断电的瞬间，继电器都不会产生误动作。

8.尺寸：5.4*1.9*1.8cm（长*宽*高）

9.重量：16g 

适用场合：

1.防盗报警延时，楼宇声光控灯开关等。

2.车载设备的延时接通，防止汽车打火时电流过大烧毁车载设备。

3.需要有顺序启动的场合，防止多个设备同时启动电流过大烧毁电器。

product description:

Wide voltage 5V-30V trigger delay relay module Timer module Delay on time Delay switch Button

Module highlights:

The time can be adjusted with a potentiometer for most of your occasions.

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

5--30V extra wide supply voltage.

Two trigger modes: external trigger and on-board button.

With relay pull-in indicator.

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

Module characteristics:

1. Working voltage: any voltage between 5-30V wide voltage, MicroUSB and soldering terminal

2. Working mode: After powering the module, the state of the module output is: normally open (NO) disconnected from the common terminal (COM), normally closed (NC) and the common terminal (COM) are turned on.

At the external contact end (TRIG), a low pulse signal is given, or when the trigger button is touched, the relay is sucked and the work indicator is bright. At this time, the state of the relay output is: normally open (NO) and the common end (COM) is turned on. Normally closed (NC) is disconnected from the common (COM). After 0-24 seconds (this time can be adjusted according to your needs), the relay is disconnected after the clock, and 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 more time, you can replace the larger capacitor (C2) or potentiometer. Delay time formula: T = 1.1 RC. For example, the capacitance 22uf resistance 1M is T=1.1*0.000022*1000000=24.2 seconds.

4. With relay pull-in indicator.

5. The module can be controlled: 10A 250VAC (AC), 10A 30VDC (DC) or less.

6. With relay freewheeling protection.

7. The signal terminal 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 does not have anti-interference effects. After the test, it is found that the stability of the trigger end can be improved to resist the interference. The module will not malfunction due to the electromagnetic interference environment or the moment when the module is powered 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.

2. The delay of the on-board equipment is turned on to prevent the current from being too large to burn the vehicle equipment when the vehicle is on fire.

3. It is necessary to have a sequence to start, to prevent multiple devices from simultaneously starting the current and burning the appliance too much.
