16路 5V继电器模块  带光耦保护 带LM2576电源

（详情提供中英文描述）

1、继电器触点容量10A 250V，带光耦保护。板载电源模块不需要外接电源。I/O口驱动低电平有效。

2、可用作单片机开发板模块，可用作家电控制，也可用作PLC扩展输出。

模块特色：

1、控制信号电压范围:触发信号为低电平。

2、抗干扰能力强，性能稳定；

3、1-16路可任意全部开启/关闭，或者任意路。

4、输出形式 ：直接接AC 220V 10A或DC30V 10A的负载。

5、每路继电器公共端COM都是独立的，方便用户接入不同的信号，每路继电器都带常闭与常开端口。

6、每路继电器都带有动作指示灯，吸合亮，断开熄灭。

7、接口设计人性化，所有接口均可通过接线端子直接连线引出，非常方便。

8、设有4个固定螺栓孔，方便安装。

9、PCB板尺寸：180MM(L)*90MM(W)*20MM(H)。

电气参数：
供电电压：5V 12V 24v (DC)

供电电流：大于200mA-500mA
每路继电器可负载：250V 10A (AC) 或30V 10A (DC)

产品使用说明：
1.供电电源要符合使用范围，直流5V 12V 24V；
2.电源按接线图要求，不可接反； 
3.产品使用LM2596S降压芯片略有发热，属正常现象，继电器长时间工作也有正常的发热现象，均属正常现象；
4.负载功率要给继电器负载留有一定的余量，应避免大功率（2000W左右）并长时间工作的环境，对产品寿命会有一定的影响。

英文描述：

product description:

application:

1, 5V relay contact capacity 10A 250V, with optocoupler protection. The onboard power supply module does not require an external power supply. The I/O port drive is active low.

2, can be used as a microcontroller development board module, can be used as home appliance control, can also be used as PLC expansion output.

Module features:

1. Control signal voltage range: The trigger signal is low level 0-2V; the high level voltage cannot exceed 5V.

2, using the industry's top quality isolated optocoupler, strong anti-interference ability, stable performance; trigger current only needs 3mA.

3, 1-16 road can be turned on/off at will, or any way.

4. Output form: Directly connect AC 220V 10A or DC30V 10A load.

5. The common terminal COM of each relay is independent, which is convenient for users to access different signals. Each relay has a normally closed and normally open port.

6. Each relay has an action indicator, which is illuminated and turned off.

7. The interface design is user-friendly, and all interfaces can be directly connected through the terminal block, which is very convenient.

8. There are 4 fixing bolt holes for easy installation.

9, PCB board size: 180MM (L) * 90MM (W) * 20MM (H).

Electrical parameters:
Supply voltage: 5V (DC)

Supply current: greater than 200mA
Each relay can be loaded: 250V 10A (AC) or 30V 10A (DC)

Product instructions:
1. The power supply should meet the scope of use, DC 5V;
2. The power supply is required according to the wiring diagram and cannot be reversed;
3. The load power should have a certain margin for the relay load. It should avoid high power (about 2000W) and work for a long time, which will have a certain impact on product life.
