Industrial Control Panels: Components, Design, and Applications
Industrial control panels bring multiple electrical and control components together into a centralized system. Depending on the application, a panel may contain programmable controls, temperature controllers, relays, power controls, circuit protection, operator interfaces, terminal blocks, and other components.
A properly designed control panel provides a central point for managing equipment and monitoring a process. Seagate Control Systems supplies individual control components and can also provide complete control panel solutions for industrial applications.
What Is an Industrial Control Panel?
An industrial control panel is an enclosure containing electrical and control equipment used to operate and monitor industrial machinery or processes.
The exact contents of a panel depend on what the system needs to control. A relatively simple application may require only a few components, while a more advanced system can include programmable controls, operator interfaces, communication equipment, temperature controls, power controls, and monitoring devices.
The panel provides an organized location for these components and their electrical connections.
Common Components Inside a Control Panel
The components used in an industrial control panel should be selected around the requirements of the equipment and process.
Programmable Controls
Programmable logic controllers can be used to manage sequences, inputs, outputs, equipment operation, and other automated functions.
Seagate offers programmable controls along with smart relay products for industrial applications.
Temperature Controls
Temperature controllers are important when a control panel is responsible for managing industrial heating equipment. The controller can receive information from a temperature sensor and regulate the heating process according to the desired setpoint.
Relays and Power Controls
Relays and power control equipment allow the control system to switch or regulate electrical loads.
Solid state relays are one option for controlling electrical heating loads. Seagate offers solid state relays and power controls as part of its industrial control product selection.
Circuit Protection
Circuit protection components help protect electrical equipment and wiring from conditions such as excessive current.
The appropriate protection depends on the electrical characteristics of the system and the equipment being controlled.
Operator Interfaces
Operator interfaces give users a way to interact with the control system. Depending on the application, an interface may allow an operator to view process information, change settings, acknowledge alarms, or control equipment.
Modern control systems can also incorporate communication capabilities so information can be shared with other equipment or systems.
Enclosures
The enclosure protects the components installed inside the control panel while providing an organized structure for the system.
Seagate offers industrial enclosures in multiple configurations and NEMA ratings, along with enclosure climate control products such as cooling fans, enclosure air conditioning units, vortex coolers, and heaters.
Why Control Panel Design Matters
A control panel is more than a collection of individual electrical components. The components must work together as part of the overall system.
Panel design should account for the electrical requirements of the equipment, the control strategy, available space, environmental conditions, operator requirements, and future service needs.
Thermal management can also be important. Components inside an enclosure generate heat during operation, and the surrounding environment can affect the internal temperature. Depending on the application, fans, heaters, air conditioning units, or other enclosure climate controls may be necessary.
Control Panels for Industrial Heating
Industrial heating applications often require several components working together.
A typical system may include a temperature sensor to measure the process, a temperature controller to determine the required heating response, a power controller or solid state relay to regulate the electrical load, and a heater to provide the actual heat.
Bringing these components together inside a properly designed control panel can provide a centralized solution for managing the heating system.
Seagate specifically offers turn key UL 508 control panels for temperature and VFD applications in addition to individual control components.
When a Custom Control Panel Makes Sense
Standard components can work well for many industrial applications, but some systems require a more specific configuration.
A custom control panel may be appropriate when an application involves multiple pieces of equipment, specialized heating requirements, multiple control loops, specific communication requirements, or unique operator needs.
Engineering support can also be valuable when determining which components need to work together. Seagate Control Systems has experienced control engineers who can assist with temperature controls, programmable controls, safety sensors, AC drives, and related industrial equipment.
Industrial Control Panel Components From Multiple Manufacturers
Industrial systems do not always require every component to come from one manufacturer. Selecting components based on the application can provide more flexibility when developing a control system.
Seagate works with more than 50 suppliers and offers a wide range of industrial control components, including programmable controls, temperature controls, power controls, relays, drives, sensors, enclosures, operator interfaces, and other panel components.
This allows an application engineer to consider the requirements of the entire system when helping customers select equipment.
Talk With an Industrial Controls Engineer
The right control panel starts with understanding what the system needs to accomplish. Electrical requirements, process conditions, heating requirements, control functions, safety considerations, and environmental conditions can all influence the final design.
Seagate Control Systems has been serving American factories since 1970 and provides both individual industrial control components and engineered control system solutions.
