How is an industrial mainboard better than an office one?

09 August 2021 Knowledge Base

Can you tell the difference between an industrial computer and an office one? Probably you can. Typically, an industrial computer is described as a specialized device with extra reliability, designed for solving various industrial tasks. This type of PC is designed to work around the clock in harsh operating conditions at high or low temperatures. An ordinary commercial-grade PC simply cannot work in such conditions and will quickly fail.

The external appearance of an industrial computer already suggests that the PC is protected fr om shock, vibration, dust, moisture and electromagnetic interference. However, the difference is not that easy to spot when we are talking about the internal components. It seems that all PCs are the same inside, with the same components installed: a mainboard, a central processing unit, RAM memory, drives, etc. In fact, there really is a lot of difference, and it is extremely important.


In another article, we have overviewed industrial flash drives and RAM modules in detail with the production of a Taiwanese company Innodisk as an example, and now we will take a look and see how an industrial motherboard differs from a commercial one and why it is necessary to use a computer based on an industrial board to solve production tasks.

Why do you need an industrial computer for your business?

The mainboard is the main component of any computing system. Thanks to it, all important components can interact with each other, thereby forming a single system, which we eventually call a computer. Why is it worth using an industrial computer in business? Here are five main reasons:

№1: Highly reliable component base. Industrial PC components have been designed and tested to withstand the harshest operating conditions. Also, all the functionality that is designed specifically for the implementation and deployment of software and hardware complex in a business environment or in production is required to be tested. An industrial computer is designed to run 24 hours a day, 7 days a week by default.

№2: Durability. In conditions wh ere a commercial PC will overheat or simply refuse to work, an industrial PC can handle the task with ease, thanks to the reliable component base of an industrial PC, which has an increased operating temperature range, making it possible to build a system without active cooling (fans), which, in turn, means excluding any possibility of dust entering the PC chassis. The lifespan of industrial computers is much longer than comparable commercial models. Moreover, high-quality materials are used in the construction of industrial computers, which are durable and long-term.

№3: Long-term support. The component base used in industrial computers is supported on average for 15 years. Also, it often can support legacy device connectivity or legacy software applications.

№4: Wide power range. Different supply voltages in a company network can make it difficult to connect computers, requiring additional power adapters and increasing the overall cost. To solve this problem, many industrial computers have an extended input voltage range of 9 VDC to 48 VDC and additional power protection circuits.

№5: Configuration flexibility. A wide selection of I/O options, interfaces and peripherals allows an industrial PC-based solution to meet a wide range of requirements.

So, what is the difference between an industrial mainboard and an office one?

Until recently, the industrial and commercial mainboard markets were divided between manufacturers. The largest manufacturers Asus, MSI and Gigabyte were only engaged in the production of commercial mainboards, all because industrial boards are typically produced in small batches in the amount of 100-1000 pieces and support a minimum life cycle of 5 to 20 years. Commercial boards, on the other hand, are produced in large batches and discontinued after 1-2 years. Industrial board manufacturers also can customize a serial board and then produce it in small batches, which commercial board manufacturers cannot.

However, over the past few years, the situation has changed. Commercial board manufacturers began offering industrial mainboards under their own brands: MSI IPC, ASRock Industrial, GIGAIPC, and AAEON (Asus). It is not yet known how this will affect the characteristics of mainboards, but we can already say that the choice options for end consumers have expanded.

Are there any other advantages of an industrial mainboard over an office one? Of course, and here is a list of the most important ones:

High quality component base. Industrial mainboards are designed to work around the clock in an industrial environment. Components for industrial boards have higher specifications than office ones. For example, industrial board capacitors are designed to operate over a wider temperature range and have a longer lifespan than commercial board capacitors.

Long service life and support. The minimum service life of an industrial mainboard is 5 years on average. Service maintenance and the availability of such cards for purchase reaches 15 years on average, in contrast to commercial ones, which become obsolete within 1–2 years.

Customization on a client’s demand. Industrial mainboard manufacturers have the option of customizing/developing boards based on the standard model, even for small quantities. In addition, manufacturers can provide a sample to the customer for testing, which commercial board manufacturers cannot offer.

Legacy interface support. Due to the long production period and variety of configurations, industrial boards still support legacy interfaces such as LPT (parallel connector, printer port) or ISA slot.

Legacy software support. If a specialized software and hardware solution is designed for a specific task based on an industrial board, then you do not have to worry that in a few years you will have to redesign the software due to the fact that the board has been discontinued or is not available for order.

Unique design and form factors. Industrial mainboards come in special form factors that may not be found in the commercial segment. For example, computers with many expansion slots are based on PICMG 1.3 boards. There are also very unique form factors, for example, PCISA. PCISA processor boards have two buses at once: PCI and ISA. Such boards are produced only by the Taiwanese company iEi.

Commercial chipset use. Most industrial mainboards are based on Intel Q-series chipsets, designed specifically for the corporate market. Intel Q-Series Chipsets combine high functionality with advanced security and administration capacities. Mainboards based on AMD chipsets are less common. Also, a separate segment of the market is occupied by mainboards based on ARM-like processors. These boards are designed for special tasks.

Based on the above differences between an industrial mainboard and a commercial one, it becomes clear that an ordinary office PC will not be able to solve production tasks in harsh operating conditions, while a computer based on an industrial mainboard will be able to work for decades in 24/7 mode, even at sub-zero temperatures. An industrial board will not go EOL in a year, and if a client needs to customize it, expand the functionality and support outdated interfaces, the manufacturer will be able to produce such a board even in small quantities.
