SR489-P1-HI-A20-E繼電器模塊是一種電氣控制裝置，當輸入量的變化達到規(guī)定要求時，可使電氣輸出電路中的被控量發(fā)生預(yù)定步進變化。它通常包括控制系統(tǒng)和被控系統(tǒng)，廣泛應(yīng)用于自動控制電路中，起到自動調(diào)節(jié)、安全保護、轉(zhuǎn)換電路等作用。
SR489-P1-HI-A20-E繼電器模塊的基本原理是它有一個動觸點和兩個靜態(tài)觸點A和b。當開關(guān)斷開時，沒有電流通過繼電器線路。此時，動觸點與靜觸點B接觸，電路上部導(dǎo)通。靜態(tài)觸點A稱為常開觸點(NO)，常處于斷開狀態(tài)?；顒佑|點也被稱為普通觸點(COM)。當電流施加到繼電器的線圈上時，線圈產(chǎn)生吸引力，使共觸點與常開觸點接觸。
以4路繼電器模塊為例，它實際上是4個繼電器組合在一起形成4個開關(guān)。每個繼電器都有自己的控制端口，如IN1、IN2、IN3、IN4，分別控制4個端口輸出。
SR489-P1-HI-A20-E是專用于1路繼電器模塊，通常具有常開接口限制大負載的特點，采用貼片式光耦隔離，驅(qū)動能力強，性能穩(wěn)定。模塊的工作電壓有多種選擇，如5V、12V、24V等。此外，該模塊可通過跳線設(shè)置高低電平觸發(fā)，具有電源指示燈和繼電器狀態(tài)指示燈，界面設(shè)計人性化，方便用戶連接和操作。

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.
