1pcs DC 12V Time Delay Relay NE555 Time Relay Shield Timing Relay Timer Control Switch Car Relays Generation Duty Cycle

1、 Size: 6.8cm * 2.1cm

二、 主要芯片：NE555

2、 Main chip: NE555

三、 工作电压：直流12伏

3、 Working voltage: DC 12V

四、 特点：

4、 Features:

1、接通电源继电器立刻吸合，然后延时1-10s断开。具体为：给继电器供12v电源后，继电器马上吸合，继电器输出端的状态为：常开与公共导通，常闭与公共断开；等到延时1-10s（可以调节）后，继电器断开，此时，继电器输出端的状态为：常开与公共断开，常闭与公共导通；只要模块不断电，此状态会一直保持。

1. When the power supply is turned on, the relay will switch on immediately, and then turn off with a delay of 1-10S.Specifically: after 12V power supply is supplied to the relay, the relay will switch on immediately, and the status of the relay output end is: normally open and common on, normally closed and common off; when the delay time is 1-10S (adjustable), the relay will be off, at this time, the status of the relay output end is: normally open and common off, normally closed and common on; as as the module is continuously powered, this status will remain.

2、延时时间可调，（0～10秒）

2. The delay time is adjustable (0-10 seconds)

4、增加电位器可以增加延时时间

4. Adding a potentiometer can increase the delay time

5、增大电容C1可以增大延时时间

5. Increasing the capacitance C1 can increase the delay time

6、具有输入电源指示灯

6. With input power indicator

7、具有继电器吸合指示灯

7. With relay pull in indicator

8、可控制交流220V/10A一下设备。（最大控制设备2000W）

8. It can control the equipment of AC 220V / 10A.(maximum control equipment 2000W)

9、具有继电器续流保护。

9. With relay freewheeling protection.

10、延时时间公式：T＝1.1RC。例如：电容100uf电阻100K T=1.1*100000*0.0001=11秒

10. Delay time formula: T = 1.1rc.For example: capacitance 100uF resistance 100k t = 1.1 * 100000 * 0.0001 = 11 seconds
