　　SR489-P1-HI-A20-E继电器模块是一种电气控制装置，当输入量的变化达到规定要求时，可使电气输出电路中的被控量发生预定步进变化。它通常包括控制系统和被控系统，广泛应用于自动控制电路中，起到自动调节、安全保护、转换电路等作用。

　　SR489-P1-HI-A20-E继电器模块的基本原理是它有一个动触点和两个静态触点A和b。当开关断开时，没有电流通过继电器线路。此时，动触点与静触点B接触，电路上部导通。静态触点A称为常开触点(NO)，常处于断开状态。活动触点也被称为普通触点(COM)。当电流施加到继电器的线圈上时，线圈产生吸引力，使共触点与常开触点接触。

　　以4路继电器模块为例，它实际上是4个继电器组合在一起形成4个开关。每个继电器都有自己的控制端口，如IN1、IN2、IN3、IN4，分别控制4个端口输出。

　　SR489-P1-HI-A20-E是专用于1路继电器模块，通常具有常开接口限制大负载的特点，采用贴片式光耦隔离，驱动能力强，性能稳定。模块的工作电压有多种选择，如5V、12V、24V等。此外，该模块可通过跳线设置高低电平触发，具有电源指示灯和继电器状态指示灯，界面设计人性化，方便用户连接和操作。

　　SR489-P1-HI-A20-E relay module is an electrical control device, when the change of the input quantity reaches the specified requirements, it can make the controlled quantity in the electrical output circuit a predetermined step change. It usually includes the control system and the controlled system, and is widely used in the automatic control circuit, playing the role of automatic regulation, safety protection, conversion circuit and so on.

　　The basic principle of the SR489-P1-HI-A20-E relay module is that it has one moving contact and two static contacts A and B. When the switch is off, no current passes through the relay line. At this time, the moving contact contacts with the static contact B, and the upper part of the circuit is on. Static contact A is called normally open contact (NO) and is normally off. Moving contacts are also known as common contacts (COM). When a current is applied to the coil of the relay, the coil creates an attractive force that makes the common contact contact with the normally open contact.

　　Take the 4-way relay module as an example, it is actually 4 relays combined together to form 4 switches. Each relay has its own control port, such as IN1, IN2, IN3, and IN4, which control four port outputs respectively.

　　SR489-P1-HI-A20-E is specific to the 1-way relay module, which usually has the characteristics of normally open interface limiting large load, adopting patch optocoupler isolation, strong driving ability and stable performance. The operating voltage of the module has a variety of choices, such as 5V, 12V, 24V, etc. In addition, the module can set a high or low level trigger through a jumper, with a power indicator and a relay status indicator, and the interface design is user-friendly, convenient for users to connect and operate.
