1路带光耦隔离支持高低电平触发继电器模块扩展板

（详情提供中英文描述）

中文描述：

 一 模块说明:

1、模块采用继电器，常开接口大负载：交流250V/10A，直流30V/10A;
2、采用贴片光耦隔离，驱动能力强，性能稳定；触发电流5mA；
3、模块工作电压有5V、12V、24V可供选择；
4、模块可以通过跳线设置高电平或低电平触发；
5、容错设计，即使控制线断，继电器也不会动作；     
6、电源指示灯（绿色），继电器状态指示灯（红色）
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、模块尺寸：50mm * 26mm* 18.5mm（长*宽*高)
9、设有4个固定螺栓孔，孔3.1mm，间距44.5mm*20.5mm
二 模块接口:
1、DC+：接电源正（电压按继电器要求，有5V、12V和24V选择）
2、DC-：接电源负
3、IN：可以高或低电平控制继电器吸合
继电器输出端：
1、NO： 继电器常开接口，继电器吸合前悬空，吸合后与COM短接
2、COM：继电器公用接口
3、NC： 继电器常闭接口，继电器吸合前与COM短接，吸合后悬空

高低电平触发选择端：

1.跳线与LOW短接时为低电平触发;

2.跳线与high短接时为高电平触发。

product description:

 A module description:

1, the module uses genuine high-quality relay, the maximum load of the normally open interface: AC 250V/10A, DC 30V/10A;
2, using patch optocoupler isolation, strong driving ability, stable performance; trigger current 5mA;
3, the module working voltage is available in 5V, 12V, 24V;
4. The module can be triggered by a jumper to set a high level or a low level;
5, fault-tolerant design, even if the control line is broken, the relay will not move;
6, power indicator (green), relay status indicator (red)
7, the interface design is user-friendly, all interfaces can be directly connected through the terminal block, very convenient
8, module size: 50mm * 26mm * 18.5mm (length * width * height)
9, with 4 fixing bolt holes, hole 3.1mm, spacing 44.5mm*20.5mm
Two module interface:
1. DC+: Connect the positive pole of the power supply (the voltage is selected according to the relay, and there are 5V, 12V and 24V options)
2, DC-: connected to the negative pole of the power supply
3, IN: can control the relay to pull high or low
Relay output:
1. NO: The relay normally open interface, the relay is suspended before the suction, and the short is connected with COM after the suction.
2, COM: relay common interface
3. NC: The relay normally closes the interface, and the relay is shorted to COM before the suction is closed.

High and low trigger selection:

1. When the jumper is shorted to LOW, it is triggered by low level;

2. When the jumper is shorted to high, it is triggered by a high level.

Third, technical parameters:
Relay version Quiescent current Maximum current Trigger current Trigger voltage (low) High
  5V 5mA 190mA 2-4mA 0-1.5V 2.5-5V
  12V 5mA 80mA 2-4mA 0-4V 4.5-12V
  24V 5mA 50mA 2-4mA 0-8V 8.5-24V
