How to Choose the Right Industrial Computer for Your Automation Needs

Industrial automation relies on the seamless integration of hardware and software to control processes, enhance productivity, and ensure operational efficiency. At the heart of many automation systems are industrial computers, which serve as control hubs for the efficient management of machines, sensors, and controllers by providing the processing power needed to carry out complex operations. With numerous types of industrial computers available on the market, selecting the right one can seem like a daunting process. To ensure that you are able to make the most informed choice for your automation needs, we will provide an overview of common types, key purchasing considerations, and current market trends in this blog.

What Are Common Types of Industrial Computers?

Depending on the particular need of an operation, there are several categories of industry computers that one can choose from. Below, we will introduce a few common options that are classified by their installation or integration characteristics.

Panel PCs: These are all-in-one computers that have their own display element, allowing operators in manufacturing settings to leverage the system as a human-machine interface (HMI) for control and monitoring purposes.

Box PCs: Box PC systems are known for their simplicity and versatility, simply being modular units that can be customized as necessary while remaining compact and adjustable enough to be inserted or mounted within various cabinets and spaces. Rackmount PCs: Such units are designed to be installed in server racks, typically found in data centers and control rooms where multiple devices need to be interconnected.

Embedded PCs: These are compact, low-power systems that are engineered to be integrated directly into the machines and equipment they manage. This is advantageous for space-constructed applications, where the unit does not need to be directly accessed by an operator often. Generally, one will find these computers in robotics, medical devices, and transportation systems.

What Are Key Purchasing Considerations for Industrial Computers?

In order to select the right industrial computer for your automation needs, it is important to be aware of the key factors that must be considered to ensure a solution that aligns with your operational demands.

Performance Requirements: The complexity of automation or operations will determine the amount of processing power that is necessary in a computer system. For example, if you are processing large amounts of data, running multiple, intensive applications simultaneously, or integrating artificial intelligence (AI) into functions, you will need a high-performing industrial computer.

Power Supply Capabilities: These systems often operate in environments where power stability is not guaranteed, so choosing a computer with a robust and adaptable power supply can better ensure uninterrupted operations. Many industrial computers also come with features like wide voltage input ranges, backup battery support, and power-fail recovery mechanisms for further benefit.

Connectivity and Expansion Features: Consider the number of external devices that need to be connected to the computer, as industrial units that offer a mix of USB, Ethernet, serial ports, and wireless connectivity will be more advantageous than those without. Additionally, expansion slots may be necessary to accommodate future upgrades, such as additional storage or enhanced communication capabilities.

Software Compatibility: Ensure that the industrial computer you choose is compatible with the software of your automation system, including operating systems, control software, and any specialized programs your industry may require.

Environmental Conditions: Industrial computers are often exposed to high temperatures, dust, moisture, and vibration, so it is important to select a unit that is rugged enough to withstand such hazards. For the highest level of safety, look for computers with industrial-grade enclosures, fanless designs, and suitable IP ratings.

What Are Current Market Trends for Industrial Computers?

The industrial computing landscape is constantly evolving, with new technologies and trends gradually shaping the future of automation. Here are just a few of the ways in which the market is changing:

Edge Computing: Edge computing is becoming increasingly popular in industrial applications, allowing data to be processed closer to the source to improve efficiency over full reliance on central servers. This reduces latency and improves real-time decision-making, rendering edge computing ideal for time-sensitive automation tasks.

AI Integration: The integration of artificial intelligence within industrial automation operations is still on the rise, with machines increasingly being able to learn from data and make more autonomous decisions to optimize processes, predict maintenance needs, and improve overall productivity.

Enhanced Cybersecurity: As industrial systems become more connected and digital attacks are on the rise, the need for strong cybersecurity measures has grown profoundly. Modern industrial computers are thus being designed with more robust security features like encrypted communications, secure boot processes, and real-time monitoring to better protect against cyber threats.

Sustainability: With the growing emphasis on sustainability across industries, manufacturers and engineers are consistently seeking ways to design computer technology that is more energy-efficient.
