1. What Is an Industrial Computer?

The core difference between an industrial computer and a standard commercial PC lies in the word "industrial-grade":

Wide temperature range: Commercial PC typically operate within 0–40°C. Industrial computers usually support -25°C to +75°C.

Fanless design: No fan means no dust intake and no bearing wear — a survival-level design in dusty or humid environments.

Wide voltage input: DC 9–36V with reverse-polarity protection, resilient to power grid fluctuations.

Vibration and EMI resistance: Certified to EMC, CE, ROHS standards, built for factory vibration and electromagnetic interference.

Long product lifecycle: Commercial PC cycle every 1–2 years. Industrial computers are typically available for 5–10 years.

In short, an industrial computer is a computing device designed for harsh environments — not a "ruggedized laptop."

2. Main Categories of Industrial Computers

Industrial computers can be divided into three major categories based on architecture, form factor, and application scenario:

2.1 By Processor Architecture

ARM vs x86: How to choose?

Data acquisition, protocol conversion, edge computing — ARM is sufficient, with power consumption only 1/5 to 1/10 of x86.

Running Docker containers, full SCADA software, video analytics — choose x86.

No air conditioning on-site, limited space, 7x24 uptime required — ARM fanless is more reliable.

2.2 By Form Factor

Form Factor	Representative Products	Mounting Method	Typical Application
Box IPC	EG628, EG828-GL, EG228	DIN rail / wall mount	Control cabinet installation, device-level control
Fanless Mini PC	EG528, EG228	DIN rail / wall mount	Data acquisition, edge computing, PLC Runtime
Panel PC	USR-SH800	Panel-embedded / DIN rail	HMI, local monitoring
Rack-mounted AI Box	EG928A	Rack / wall mount	Edge AI, video analytics, visual inspection

2.3 By Application Scenario

Scenario	Recommended Type	Core Requirements
PLC Runtime	ARM box IPC	Multiple serial ports, DI/DO, CAN bus, real-time capability
SCADA / HMI	Panel PC or x86 IPC	Touchscreen, multi-display, large data volume
Edge AI	AI Box	NPU compute, video interfaces, AI framework support
IoT Gateway	ARM gateway	Multi-protocol, 4G/WiFi, remote management
Docker Deployment	x86 IPC	Large memory, large storage, full Linux

3. Scenario-Based Selection: Which Fits Your Project?

Scenario 1: PLC Programming and Runtime

If the project requires using an industrial computer as a PLC — for example, running OpenPLC or replacing a traditional PLC for logic control — you need:

● ARM box IPC  with rich I/O interfaces
● 2–4 RS485 serial portsminimum, to connect field devices
● DI/DO digital input/output, for sensors and actuators
● CAN bus, for CAN-based devices

Reference model: USR-EG628 (RK3562J processor, supports PLC programming, built-in WukongEdge engine, native Node-RED support, 2×RS485 + 1×RS232 + 1×CAN + 2×Ethernet)

Industrial PC computer EG628 allows writing PLC programs directly on the computer, paired with WukongEdge for data acquisition and logic control — eliminating the cost of a standalone PLC.

Scenario 2: SCADA System / Data Monitoring

SCADA systems require stable data acquisition and visualization:

Small SCADA (single machine, < 500 points): ARM box IPC with configuration software for local monitoring.
Medium SCADA (500–2,000 points): High-performance ARM IPC such as EG828-GL (RK3568, quad-core 64-bit, 2.0GHz).
Large SCADA (server-side): x86 IPC (EC300/EC500) — stronger performance, runs full SCADA software.

Key point: EG628 and ARM-based Industrial PC EG528 include the WukongEdge engine, supporting 2,000 real-time points. Local data monitoring is completed in three steps with configuration software — no additional development needed.

Scenario 3: HMI (Human-Machine Interface)

The core of HMI is human interaction — touch screen plus local display:

Panel-embedded IPC: USR-SH800 is the typical choice
● 10.1-inch capacitive touchscreen, 800×1280 resolution
● RK3568 processor, 1.0 TOPS NPU
● Built-in Node-RED visual programming, drag-and-drop interface building
● Supports wet-hand and gloved operation
● IP65 front-panel protection

Panel PC vs. Standard PC + Monitor:

● Tight control cabinet space, need embedded mounting → choose Panel PC
● Harsh environment (dust, humidity) → choose Panel PC (sealed front panel)
● Need 21.5-inch+ large display, or multi-monitor setup → PC + monitor is more economical

Scenario 4: Edge AI / Visual Inspection

Edge AI has clear compute requirements — look at NPU TOPS:

● Lightweight AI (simple classification, counting): 1.0 TOPS NPU is sufficient (EG828-GL)
● Moderate to heavy AI (face recognition, license plate recognition, defect detection): 6.0 TOPS NPU required (EG928A)
● Video analytics (multi-camera): Requires 8K codec support + multi-camera input

Reference model: USR-EG928A (RK3588J processor, 6 TOPS NPU, supports LPDDR4 8GB + 128GB eMMC, connects up to 32 IP cameras, supports TensorFlow/ONNX/Darknet and other mainstream AI frameworks)

Edge AI Box EG928A also supports AI acceleration card expansion, suitable for projects that may need compute upgrades later.

Scenario 5: IoT Gateway / Data Acquisition

The core capability of an IoT gateway is "connectivity" — connecting field devices to the cloud:

● Multi-protocol support: Modbus, IEC 61850, IEC 104, DL/T 645, DNP3.0, BacNet, etc.
● Multi-network redundancy: 4G + WiFi + Ethernet, automatic failover
● Edge computing: Data preprocessing, protocol conversion, store-and-forward
● Remote management: Web configuration, remote programming, firmware updates

Reference models:

● Lightweight: Fanless Industrial Computer USR-EG228(RK3506J, 512MB RAM, 2×RS485 + 2×CAN FD, suitable for small-scale data acquisition nodes)
● Medium: ARM-based Industrial PC USR-EG528(RK3562, 4×RS485, built-in SCADA/HMI, Node-RED support)
● Open-source development: Arduino Open Source IoT Gateway USR-EG118(ESP32, Arduino IDE support, suitable for DIY and small-batch customization)

Scenario 6: Docker Container Deployment

Docker requires a full Linux environment with adequate memory and storage:

● ARM architecture: Arm industrial pc EG828-GL (4GB DDR + 32GB eMMC, pre-installed Node-RED and Docker)
● x86 architecture:  X86 industrial pc EC100/EC300/EC500 (stronger performance, compatible with all Docker images)

Note: ARM Docker images are limited in number. If running x86-only containers (e.g., certain databases, middleware), choose x86 for better compatibility.

Scenario 7: Energy Management System (EMS)

Energy storage power stations and solar inverters require:

● Dedicated EMS gateway: EG828-EMS
● Multi-protocol support: Modbus RTU/TCP, MQTT
● Rich I/O: 4×Ethernet, 8×RS485, 2×CAN, 16×DI, 16×DO
● Solar-storage-charging microgrid solution support

EG828-EMS is purpose-built for solar-storage-charging scenarios, connecting to smart energy storage monitoring platforms, supporting data reporting and remote command execution.

4. Selection Checklist: Three Questions, Three Checks

When selecting, start with these three questions:

Question 1: Is the processor powerful enough?

● Light acquisition → ARM entry-level (EG228, RK3506J)
● Medium processing → ARM mid-range (EG528/EG628, RK3562)
● High performance → ARM high-end (EG828-GL, RK3568)
● AI inference → RK3588 (EG928A/EG1000)
● Heavy workloads → x86 (EC100/EC300/EC500)

Check 2: Are the interfaces sufficient?

The field devices dictate the interfaces:

● RS485/RS232 serial ports: For Modbus devices, meters, instruments
● Ethernet ports: For OPC UA servers, SCADA, network equipment
● DI/DO: For sensors, relays, actuators
● CAN bus: For CAN devices, vehicle-mounted equipment
● Video interface (HDMI): For monitors, cameras

Check 3: Is the environment compatible?

● Temperature range: Factory workshops need -25°C to +75°C wide-temperature models
● Protection level: Dusty environments require fanless passive cooling
● Power conditions: Unstable grids need wide voltage input (DC 9–36V)
● Vibration: Fanless, no-moving-parts models are the way to go

5. Frequently Asked Questions

Q1: What is the difference between an ARM industrial computer and an x86 industrial computer?

ARM architecture offers low power consumption, compact size, and fanless cooling — ideal for edge acquisition and IoT gateways. x86 architecture delivers higher performance and broader software compatibility — suited for SCADA servers, Docker deployment, and video processing. Choose the architecture based on application needs first.

Q2: What is the difference between a fanless industrial computer and a standard industrial computer?

Fanless designs dissipate heat through a solid metal chassis. No fan means no dust intake and no bearing wear — better suited for dusty, humid industrial environments. The trade-off is lower processing performance — but most edge applications don't require top-end performance.

Q3: What is the difference between an industrial computer and a commercial PC?

Industrial computers support wide-temperature operation (-25°C to +75°C), wide-voltage input (DC 9–36V), vibration and EMI resistance, and carry CE, ROHS, FCC certifications. Commercial PCs typically operate within 0–40°C on stable power, and are not designed for harsh industrial environments.

Q4: Which industrial computer is suitable for PLC?

Projects requiring PLC Runtime should choose an ARM box IPC with rich I/O, such as the USR-EG628. It supports PLC programming (OpenPLC, IEC 61131-3 compliant), with built-in RS485 and CAN bus for direct field device connection.

Q5: Which industrial computer is suitable for HMI?

Panel-embedded IPCs are the first choice for HMI, such as the USR-SH800. It features a built-in touchscreen (10.1-inch capacitive), configuration software, drag-and-drop interface building, and supports wet-hand and gloved operation.

Q6: Which industrial computer supports Docker?

Both EG828-GL (ARM, 4GB DDR) and EC100/EC300/EC500 (x86) support Docker. ARM images are limited; for x86-only containers (databases, middleware), choose x86 models.

Q7: Which industrial computer is suitable for Edge AI?

USR-EG928A is the top choice for edge AI. It features an RK3588J processor with 6 TOPS NPU, supports TensorFlow/ONNX/Darknet, connects up to 32 IP cameras, and is suitable for face recognition, license plate recognition, and visual inspection.

Q8: What is the significance of industrial computer certifications?

CE, ROHS, FCC, 3C certifications are market entry requirements for different regions and indicate that the product meets industrial standards for electromagnetic compatibility, safety, and environmental compliance. For export projects, target-market certification requirements (e.g., CE for EU, FCC for US) are especially important.
