Electrical control devices are generally referred to as secondary control circuits for electrical equipment. Different devices have different control circuits, and the control methods for high-voltage and low-voltage electrical equipment are also different. Specifically, an electrical control system refers to a combination of several electrical components used to control a certain object or objects, thereby ensuring the safe and reliable operation of the controlled equipment. Its main functions include automatic control, protection, monitoring, and measurement. The so-called electrical control device refers to a combination of several electrical components used to control a certain object or objects, thereby ensuring the safe and reliable operation of the controlled equipment. The main functions of electrical control devices include automatic control, protection, monitoring, and measurement. It mainly consists of three parts: input part (such as sensors, switches, buttons, etc.), logic part (such as relays, electric shock, etc.), and execution part (such as electromagnetic coils, indicator lights, etc.)
