PLC control cabinets are electrical equipment. Here are the specific reasons:
From the definition point of view: electrical equipment is a general term for generators, transformers, power lines, circuit breakers and other equipment in the power system. It is a general term for various equipment used in power generation, transmission, distribution, and power consumption. PLC control cabinets are mainly composed of programmable logic controllers (PLCs), circuit breakers, contactors, relays, power supplies and other electrical components. Its function is to control and monitor industrial automation systems, realize logical control of equipment, data processing and other functions, and play an important role in power distribution and power consumption, which meets the definition of electrical equipment.
From the perspective of functional characteristics
Electric energy conversion and distribution: PLC control cabinets can distribute and convert input electrical energy, provide appropriate power for PLC and other electrical components, and ensure their normal operation. For example, converting the 220V AC power of the mains into the 24V DC power required by the PLC is one of the typical functions of electrical equipment.
Signal processing and control: PLC control cabinets can receive electrical signals from sensors and other equipment, and after logical operations and processing by PLC, output control signals to drive actuators such as motors and solenoid valves. This processing and utilization of electrical signals to achieve control functions is an important feature that distinguishes electrical equipment from other non-electrical equipment.
Electrical connection and protection: PLC control cabinets have a large number of electrical connection lines inside, which are used to connect various electrical components to form a complete control circuit. At the same time, it is also equipped with protection devices such as fuses and thermal relays to protect circuits and equipment from electrical faults such as overload and short circuit, which is also an important function and feature of electrical equipment.
From the perspective of application scenarios: PLC control cabinets are widely used in automation control systems in various fields such as industry, agriculture, construction, transportation, etc., and work together with other electrical equipment such as motors, inverters, sensors, etc. to form a complete electrical automation system to achieve precise control and monitoring of production processes and equipment operations.
