Panel PC vs Box PC: Which Industrial Computer Is Right for You?

TSL Automation Solutions February 11, 2025

What Is a Panel PC?

An industrial Panel PC integrates a touchscreen display, computer, and power supply into a single sealed unit. It mounts flush into a control panel cutout, presenting a clean interface to the operator. Panel PCs are ideal where the operator interacts with the screen directly.

What Is a Box PC?

An industrial Box PC (also called a fanless embedded computer) is a standalone computing unit without a built-in display. It connects to one or more external monitors via HDMI, DisplayPort, or LVDS. Box PCs are typically smaller and can be mounted in inconspicuous locations — inside a panel, on a DIN rail, or remotely from the operator station.

Panel PC vs Box PC: Key Differences

Feature	Panel PC	Box PC
Display	Integrated touchscreen	Separate external monitor
Installation	Panel cutout mount	DIN rail, shelf, or VESA mount
Operator access	Direct touch	Mouse, keyboard, or touch (separate)
Upgrade flexibility	Replace whole unit	Upgrade PC or display independently
Multi-screen	Typically 1 screen	Supports 2–4 monitors easily
Typical use	Operator station, HMI	SCADA server, data logger, IoT gateway

When to Choose a Panel PC

The operator needs a touchscreen interface directly on the machine
Panel space is limited — one unit vs two separate items
IP65 front panel sealing required for washdown environments

When to Choose a Box PC

Running a SCADA server with multiple monitors
Hidden installation away from the operator (inside a panel, in a rack)
Need to upgrade the display and computer on different schedules
Running headless (no display) as a data acquisition server or IoT gateway

Frequently Asked Questions

What is the difference between an industrial Panel PC and a Box PC?

An industrial Panel PC integrates the display, touchscreen, and computer in one sealed unit — designed for panel mounting with the display facing the operator. A Box PC is the computing unit only, without an integrated display — connected to a separate monitor or HMI panel. Panel PCs reduce cabling complexity and panel cutout size; Box PCs offer flexibility to connect different display types and sizes.

When should I choose a Panel PC over a Box PC?

Choose a Panel PC when: you want a single integrated operator interface with integrated display and touch, you have adequate panel depth for the Panel PC chassis, you need IP65 sealed touch display at the operator station. Choose a Box PC when: you need to connect to an existing monitor, require a larger or different display than standard Panel PC sizes, or need to mount the computing unit separately from the display (e.g., computer in a cool control room, display on a hot machine).

Which is easier to maintain — a Panel PC or a Box PC with separate display?

Box PCs with separate displays are easier to maintain because the computer and display can be replaced independently. If the display fails on a Panel PC, the whole unit often needs replacement or depot repair. A Box PC with a separate display allows replacing just the failed component. However, Panel PCs have fewer cable connections and a cleaner installation with less potential for vibration-related connector issues.

What Panel PC sizes does TSL Automation offer?

TSL Automation Solutions supplies Avalue Panel PCs from 7" to 21.5" in multiple processor configurations (Celeron to Core i7). We also supply Cermate HMI panels from 4.3" to 21.5" for PLC-connected operator interfaces. Contact our Mumbai team for size and specification recommendations for your specific operator interface application.

Can a Box PC and Panel PC run the same SCADA software?

Yes — both run identical Windows 10/11 IoT or Linux operating systems and are fully compatible with any SCADA, MES, HMI, or industrial software. The choice between Panel PC and Box PC is based on physical installation requirements, not software compatibility.
