Control panels are used to receive inputs, trigger outputs, and monitor systems and instrumentation. They are used in a variety of industrial, manufacturing and process control applications. There are many different types of control panels. Examples include access control panels, electrical control panels, motor control panels, and pump control panels. Access control panels are used in security systems to limit unauthorized access to office buildings, manufacturing facilities, or processing plants. Electrical control panels monitor and regulate the flow of electricity into a building or structure. Motor control panels are used with various types of AC motors and DC motors. Similarly, pump control panels are used with all manner of industrial pumps. Some industrial control panels have a basic interface and offer limited functionality. Others are complete control panel systems that include hardware, software, and controller cards. Lighting control panels, HVAC control panels, and custom control panels are also available.
