From PLC-based control panels to MCC panels and automation cabinets, AutomateXLab helps businesses build safe, scalable, and standards-compliant control systems, backed by complete electrical documentation.
What Is Industrial Control Panel Design?
Control panel design is the process of creating electrical enclosures that house PLCs, HMIs, relays, VFDs, power supplies, and communication devices required to automate industrial operations.
A complete control panel design covers panel layout planning, component selection, electrical schematics, safety compliance, power distribution design, and network architecture. Getting this stage right determines how reliable the panel is once it is running production, and how easy it is to troubleshoot years later.

Frequently Asked Questions
What is included in a control panel design package?
A typical package includes electrical schematics, panel layout drawings, a bill of materials, an I/O list, power calculations, and a full documentation package used for manufacturing and commissioning.
Can you design PLC and SCADA panels?
Yes. We design PLC, HMI, SCADA, MCC, VFD, and custom automation control panels for manufacturing, process, and machine builder applications.
Which PLC brands do you support?
We design panels around Siemens, Allen-Bradley, Schneider Electric, Mitsubishi, Delta, and other major PLC platforms based on the project requirement.
Do you provide panel manufacturing?
We focus on engineering and design. We support panel builders with complete documentation, including schematics, layouts, and BOMs, so manufacturing and implementation go smoothly.
Can you redesign existing control panels?
Yes. We can review and modernize outdated panels, improving component layout, safety compliance, documentation, and maintainability without necessarily rebuilding the panel from scratch.
How do you calculate panel heat load?
Heat load is calculated by summing the watt loss of every component in the enclosure, including drives, power supplies, and contactors, then comparing that total against the enclosure’s surface area and ambient temperature to size cooling or ventilation correctly.
How do you size a power supply?
Power supply sizing starts with adding the current draw of every 24V DC load in the panel, including PLC modules, relays, and sensors, then applying a safety margin, typically 20 to 25 percent, to account for inrush current and future additions.
How do you select breakers?
Breaker selection is based on the full load current of the circuit it protects, the type of load, such as motor or resistive, and coordination with upstream and downstream protective devices to prevent nuisance trips or under-protection.
How do you choose wire gauges?
Wire gauge is selected based on the current the conductor will carry, the length of the run, allowable voltage drop, and the ambient temperature inside the panel, following NFPA 79 or IEC 60204 ampacity tables depending on the applicable standard.
How do you plan spare I/O?
We typically recommend reserving 15 to 20 percent spare I/O capacity on both digital and analog channels, and specifying a PLC chassis or rack with open module slots, so future sensors or devices can be added without a controller swap.
Can the panel support future expansion?
Yes, when this is planned for at the design stage. This includes sizing the enclosure larger than the initial component footprint, adding spare terminal blocks, reserving I/O capacity, and selecting a PLC platform with room to scale.
Which communication protocol should I choose?
The right protocol depends on your existing infrastructure and performance needs. Ethernet/IP and Profinet suit high-speed, Ethernet-based architectures, Modbus TCP works well for simpler integrations, and OPC UA is the standard choice when SCADA or IT-level data access is required.
How long does panel design usually take?
A single control panel typically takes two to four weeks from requirement analysis to final documentation. Multi-panel systems or projects with complex safety and networking requirements can take six to ten weeks.
Control Panel Engineering, Explained
What Is a PLC Control Panel?
A PLC control panel is an enclosure that houses a programmable logic controller along with the relays, terminals, power supplies, and I/O modules it needs to control a machine or process. The PLC reads inputs from sensors and switches, executes the control logic, and drives outputs to motors, valves, and actuators, all through wiring terminated inside the panel.
Control Panel Design Standards Explained
Control panel design standards define how a panel should be built to be safe, consistent, and serviceable. IEC 60204 covers the electrical equipment of machines, IEC 61439 covers low-voltage switchgear and controlgear assemblies, NFPA 79 is the North American equivalent for industrial machinery, and UL 508A governs industrial control panel construction in the United States where UL listing is required. Following the correct standard for your region and industry is what allows a panel to pass inspection and insurance review.
Control Panel Design Checklist
A practical checklist covers defining the I/O count and voltage levels, selecting an enclosure rating suited to the environment, calculating heat load and power supply sizing, choosing breakers and wire gauges for the expected current, planning terminal and cable layout for serviceability, reserving spare I/O and space for expansion, and producing complete schematics, a BOM, and a layout drawing before manufacturing begins.
Common Control Panel Design Mistakes
The most frequent mistakes are undersizing the power supply without accounting for inrush current, routing power and signal wiring too close together, skipping heat load calculations on panels with VFDs or dense component packing, leaving no spare I/O or terminal capacity, and delivering a panel without labeled schematics or an as-built drawing. Each of these creates either a reliability problem or a maintenance headache later.
PLC vs MCC Panels
A PLC panel houses the controller and logic that automates a process, while an MCC, or Motor Control Center, is built specifically to start, stop, and protect multiple motors, typically pumps, fans, and compressors, from a centralized set of starters and breakers. Many facilities use both together, with the PLC panel issuing start and stop commands that the MCC executes at the motor level.
How to Select Components for an Industrial Control Panel
Component selection starts with the process requirements, not a brand preference. The PLC needs enough I/O and processing headroom for the application plus spare capacity, breakers and contactors need to match the calculated load, the enclosure rating needs to match the environment, whether that’s a clean office-adjacent panel or a washdown food production area, and communication modules need to match whatever SCADA or network architecture already exists on site.
Cost of Industrial Control Panel Design
Control panel design cost depends primarily on I/O count, the complexity of the control logic, the number of communication protocols involved, and whether the project requires UL listing or a specific regional compliance standard. A single-machine panel with a modest I/O count costs meaningfully less than a multi-zone panel with SCADA integration, redundant power, and expansion built in. We provide a project-specific quote once the requirement analysis stage defines the scope.
Future Trends in Smart Control Panels
Control panels are increasingly designed with built-in connectivity for IIoT platforms, edge devices that pre-process data before it reaches a SCADA or cloud system, and OPC UA as a default rather than an add-on. Predictive maintenance is also shaping panel design, with current and vibration sensors now specified at the design stage rather than retrofitted later, so panels are built to report their own health over time.
