How to choose the right industrial PC for your application

Whether you're automating a production line, running data acquisition software, or managing industrial IoT systems, the industrial PC you choose needs to align with your specific requirements. But what is an Industrial PC?

An industrial PC is a computer specifically designed for harsh environments, built to withstand extreme temperatures, vibration, shock, dust, and sometimes even water or chemicals. Unlike consumer PCs, industrial PCs prioritise reliability and long-term operation, often running 24/7 in demanding conditions.

Industrial PCs can come in a variety of form factors, from fanless compact designs to larger, fully rugged enclosures. The industrial PC market has grown rapidly, with leading manufacturers like DFI producing systems that meet the needs of smart manufacturing, automation, transportation, and energy industries. Let's explore some of the key factors to consider when choosing your industrial PC.

1. Performance requirements (CPU and memory)

Your choice should start with understanding your processing needs. Are you running machine vision applications that need significant GPU power, or just basic data logging that requires low processing overhead?

For heavy processing, consider the VC500-CMS-MXM, which supports Intel Xeon processors and up to 64GB memory. For lighter applications, the EC700-ADN offers efficient Intel Atom performance with a compact footprint.

2. Environmental conditions

Will the system operate on a clean production floor, or will it be exposed to outdoor conditions, dust, vibration, or moisture? For rugged environments, the ECX700-ADP with IP67/IP69K certification offers superior protection against water and dust. For controlled environments, the EC543-ADS balances performance with cost for standard industrial setups.

3. Form factor and mounting options

Space constraints are common in industrial settings, so understanding the size and mounting flexibility matters. For ultra-compact installations the EC70A-ADP (181.6 x 57 x 118.4mm) fits where space is extremely limited. For expandable systems the VC500-CMS offers flexibility without compromising on processing power.

4. Connectivity, expansion, and operating system compatibility

What peripherals and devices will your system need to interface with? Check for necessary ports - DisplayPort, HDMI, USB, VGA - and expansion slots for future upgrades.

Another critical factor is the operating system (OS). Relec's partners can pre-load or offer Windows 10, Windows 11, and for select models, Linux - giving you the flexibility to choose the platform that best supports your industrial applications.

All DFI industrial PCs featured on our site offer a versatile mix of ports and OS compatibility, ensuring seamless integration with both modern software and legacy industrial systems.

5. Operating temperature range

From freezing cold outdoor sites to scorching hot factory floors, your industrial PC needs to endure it all. Both the VC500-CMS and ECX700-ADP handle temperatures as low as -20degC and up to 70degC. For more moderate climates, systems like the EC543-ADS work well in standard industrial temperatures up to 60dedC.

Why choosing the right industrial PC matters

Getting the choice of industrial PC is important, because selecting the wrong system can lead to: unexpected system failures and costly downtime; compatibility headaches with sensors, cameras, or machinery; and performance bottlenecks that slow down operations.

On the flip side, investing in a tailored industrial PC ensures long-term reliability in harsh environments, seamless integration with your existing infrastructure and scalable performance that grows with your needs.

There are a number of common challenges, not least of which is balancing performance and cost; not every application needs the most powerful processor. Evaluate your software's real requirements and choose accordingly. Consider future-proofing, though; you may need more processing power down the road as applications become more advanced.

When it comes to environmental protection, if your PC is exposed to outdoor or factory-floor hazards, choose rugged systems like the ECX700-ADP with IP67/IP69K protection.

Finally, consider compatibility with existing equipment. Legacy machinery may rely on older interfaces like VGA. Be sure your new PC includes all necessary ports for seamless integration.

In conclusion, choosing the right industrial PC for your application isn't just about specs - it's about ensuring seamless operation, long-term reliability and adaptability to future demands. By carefully assessing your environment, processing needs, and connectivity requirements, you can select the perfect system to power your industrial application.
