CM902WM 模块可以通过跳线设置高电平或低电平触发

继电器控制模块是一种电控制器件，CM902WM通常应用于自动化的控制电路中，起着自动调节、安全保护、转换电路等作用。它具有控制系统和被控制系统，当输入量的变化达到规定要求时，在电气输出电路中使被控量发生预定的阶跃变化。

CM902WM 继电器控制模块的种类有很多，如4路继电器模块、1路继电器模块等。其中，4路继电器模块是将4个继电器合并在一起，变成4个开关，IN1、IN2、IN3、IN4分别控制4个端口输出。而1路继电器模块通常常开接口限大负载，交流250A10A，直流30v/10A，采用贴片光耦隔离，驱动能力强，性能稳定，触发电流5mA，模块工作电压有5V、12V、24V可供选择（注意连接是否为所需电压），模块可以通过跳线设置高电平或低电平触发，电源指示灯（绿色），继电器状态指示灯（红色），接口设计人性化，接口均可通过接线端子直接连线引出。

此外，还有一些具有光耦进行隔离、驱动能力强、性能稳定等特点的继电器控制模块。这些模块通常具有性价比超高、宽电压设计、6路继电器控制输出、隔离RS485通讯接口、带光耦隔离避免高电压电路干扰、带继电器指示灯方便查看继电器的工作状态、提供配套软件支持二次开发等特点。

Relay control module is an electrical control device, CM902WM is usually used in automatic control circuit, plays the role of automatic regulation, safety protection, conversion circuit and so on. It has a control system and a controlled system, and when the change of the input quantity reaches the specified requirements, the controlled quantity will undergo a predetermined step change in the electrical output circuit.

There are many types of CM902WM relay control modules, such as 4-way relay module, 1-way relay module, etc. Among them, the 4-way relay module is to combine 4 relays into 4 switches, IN1, IN2, IN3, and IN4 respectively control 4 port output. The 1-way relay module is usually open to limit large loads, AC 250A10A, DC 30v/10A, using patch optocoupler isolation, strong driving ability, stable performance, triggering current 5mA, module operating voltage is 5V, 12V, 24V to choose from (pay attention to whether the connection is the required voltage). The module can set high level or low level trigger by jumper, power indicator (green), relay status indicator (red), interface design is humanized, and the interface can be directly connected through the terminal.

In addition, there are some relay control modules with optocoupler isolation, strong driving ability and stable performance. These modules usually have the characteristics of ultra-high cost performance, wide voltage design, 6-way relay control output, isolated RS485 communication interface, with optocoupler isolation to avoid high-voltage circuit interference, with relay indicator light to facilitate viewing the working status of the relay, and provide supporting software to support secondary development.
