Panel PCs, HMIs and control modules are not interchangeable

Three kinds of product share this area. A panel PC is a complete computer behind a touchscreen, usually running Windows, so it can host software and databases. An HMI is a dedicated touch display for operating a machine, usually tied to one controller maker's software. Control modules, such as delay relays, output boards and remote receivers, switch loads rather than display anything. Settle which of these you need before you compare screen sizes, which run from about 10 to 17 inches.

Processor generation, memory type and what storage is included

On a panel PC, the processor generation matters as much as the model name: a Celeron is basic, while Core i5 and i7 chips handle heavier software. Memory type is DDR3 or DDR4 and the two do not swap. Windows 11 officially supports only recent processors, such as 8th-generation Intel Core and newer, so check that the chip in a Windows 11 unit is on Microsoft's supported list. Some listings show no drive, so confirm storage is included, and check mounting, front-panel protection and supply voltage.

Questions about Panel PCs, Touchscreen HMIs and Control Modules

What is the difference between a panel PC and an HMI?
A panel PC is a full computer with a built-in screen, usually running Windows, so it can run several programs. An HMI is a touch display built to operate a machine and is normally programmed with its controller maker's own software. Choose by what must run on it.
Can I upgrade the memory in an all-in-one panel PC?
Sometimes. DDR3 and DDR4 modules are physically different, and some panel PCs use soldered memory with no slot at all. Look up the exact model for slot type, supported speed and maximum capacity before choosing modules.
What should I check before mounting a panel PC?
Check the cutout size or VESA hole pattern, the supply voltage, and how the unit sheds heat, since fanless designs still need space around the case. For dusty or wet areas, look for a stated ingress protection rating on the front panel.
