What Is the B&R Panel PC 3100?
The B&R Panel PC 3100 is an industrial panel PC from B&R Industrial Automation that combines a PC unit with a panel-mount display into a single system. According to B&R's own product documentation, the PC unit can be paired with any panel-mount Automation Panel with a diagonal of 10.1" or larger, giving machine builders a scalable, integrated operator interface. It sits alongside B&R's Automation PC 3100, which is designed to control remote panels rather than mount directly on a machine. The 3100 family is aimed at machine-level HMI and control tasks in factory automation.
Key Characteristics of Panel-Mount Industrial PCs
Panel PCs like the 3100 series are built to be mounted into the front of a control cabinet or machine enclosure, so the display faces the operator while the PC electronics sit behind the panel. This form factor is common in manufacturing, packaging, food processing, and process control, where a sealed front panel resists dust, moisture, and washdown. Buyers evaluating this class of hardware typically compare:
| Consideration | What to Evaluate |
|---|---|
| Display size | Typically 10.1" to 24", single or multi-touch |
| Processor | Intel Celeron, Core i3/i5 depending on workload |
| Cooling | Fanless (passive) vs. fan-cooled |
| Memory / storage | 4–32 GB RAM, 128 GB–1 TB SSD |
| I/O | Gigabit Ethernet, USB, HDMI, serial |
| Operating system | Windows 11 IoT/Pro, Linux, or no OS |
| Mounting | Panel-mount cutout, VESA, or arm mount |
Choosing an Alternative or Replacement
If you are specifying a panel PC for a new machine or looking for an alternative to an existing panel PC platform, the practical questions are the same: what software will run on it, how much I/O does the machine need, and what environmental conditions must it survive? Fanless designs are often preferred because they remove a moving part that draws in dust and requires filter maintenance. Wide-voltage DC inputs, isolated serial ports, and industrial temperature ratings matter more on a factory floor than raw benchmark scores. It is also worth confirming long-term availability and OS support, since industrial equipment often stays in service for many years.
Typical Applications
Panel PCs in this class are used for machine HMI, SCADA terminals, production line monitoring, CNC and motion control front ends, building automation, and kiosk or terminal installations. Common requirements include 24/7 operation, resistance to vibration and temperature swings, and the ability to run either Windows-based HMI software or a Linux-based stack.
Thinvent Industrial Panel PCs
Thinvent manufactures industrial panel PCs, mini PCs, thin clients and all-in-one computers for customers worldwide, and offers a strong alternative to panel-mount systems such as the B&R Panel PC 3100. Thinvent's 15" industrial panel PC pairs an Intel processor N5095A (4 cores, up to 2.9 GHz, 4 MB cache) with 16 GB DDR4 RAM and a 1 TB SSD, powered by a 12V 5A adapter. It is available with Windows 11 IoT, Windows 11 Pro, DOS, or Thinux embedded Linux, with or without a keyboard and mouse set, so you can match the OS to your HMI or control software. For deployments that need different screen sizes, processors, memory, storage, or I/O, Thinvent's range covers mini PCs, thin clients, all-in-one units and industrial PCs to suit a variety of machine and factory-floor requirements.
