保护和安全继电器因为它们主要用作工业系统和机器中的保护机制。这两种类型的继电器是不同的，并且它们的实现标准也彼此不同。

以下是两种继电器的简要比较:

保护继电器的功能取决于外部变量，如电压或电流。另一方面，安全继电器专门设计为检测相关危险的安全装置。

保护继电器需要外部元件，如电流互感器，以集成到电气系统中。安全继电器可以直接集成到主控制器中，用于进一步处理或自动化过程。

保护继电器通常安装在类似于其他普通电气或电子元件的配电板中。安全继电器的安装需要适当的物理尺寸来覆盖危险区域。

如前所述，保护继电器的例子包括接地故障、接地漏电和过电压。安全继电器检查是否存在触发的安全装置，如光幕、牵引链或紧急停止(e-stop)按钮。

Protection and safety relays are mainly used as protection mechanisms in industrial systems and machines. These two types of relays are different, and their implementation standards are also different from each other.

Here is a brief comparison of two types of relays:

The function of a protective relay depends on external variables such as voltage or current. On the other hand, safety relays are specifically designed as safety devices to detect related hazards.

Protective relays require external components, such as current transformers, to be integrated into electrical systems. Safety relays can be directly integrated into the main controller for further processing or automation processes.

Protective relays are usually installed in distribution boards similar to other ordinary electrical or electronic components. The installation of safety relays requires appropriate physical dimensions to cover hazardous areas.

As mentioned earlier, examples of protective relays include ground faults, ground leakage, and overvoltage. Check for triggered safety devices such as light curtains, traction chains, or emergency stop (e-stop) buttons on safety relays.
