| Display Size | 10.1–24 inches; common resolutions include 1280 × 800, 1366 × 768, and 1920 × 1080 pixels. | A larger display can improve visibility of dashboards, alarms, process diagrams, and production data. | Match the screen size and resolution to operator viewing distance, available panel space, and application layout. |
| Touch Technology | Projected capacitive touch, resistive touch, or non-touch display; many systems support glove or stylus operation when specified. | The correct touch method supports reliable operation in clean rooms, workshops, outdoor areas, or environments where gloves are used. | Confirm glove compatibility, wet-finger performance, chemical resistance, and the required number of touch points. |
| Operating Temperature | Industrial models commonly offer ranges such as -20°C to 60°C or 0°C to 50°C, depending on the configuration. | A suitable temperature range helps reduce unexpected shutdowns and performance degradation. | Calculate the actual ambient temperature inside the enclosure, including heat generated by the computer and nearby equipment. |
| Ingress Protection | Front-panel ratings commonly range from IP65 to IP69K; the exact rating depends on the enclosure and installation method. | Protection against dust and water supports dependable operation in manufacturing, food processing, and washdown areas. | Select the rating according to dust exposure, water pressure, cleaning chemicals, and whether the rear of the unit is protected. |
| Processor Performance | Configurations may use low-power processors for HMI tasks or higher-performance multi-core processors for machine vision, analytics, and virtualization. | Adequate processing capacity improves response time and allows the system to run required software without excessive hardware upgrades. | Define the number of applications, data-processing workload, connected devices, and expected service life before choosing the CPU. |
| Memory and Storage | Typical configurations range from 4–32 GB RAM and 64 GB–1 TB solid-state storage, depending on workload and operating system. | Sufficient memory and solid-state storage support faster startup, application stability, local data logging, and reduced sensitivity to vibration. | Estimate software requirements, log retention, database size, backup needs, and future expansion. |
| Industrial Connectivity | Common interfaces include Gigabit Ethernet, USB, serial ports such as RS-232/422/485, digital I/O, and display outputs. | Direct connectivity can simplify integration with PLCs, sensors, scanners, drives, cameras, and factory networks. | List every current and planned device, protocol, connector type, cable length, and network redundancy requirement. |
| Mounting Method | Panel mount, VESA mount, wall mount, arm mount, and rack-related installation options are commonly available. | A suitable mounting method improves ergonomics, cable management, service access, and protection against accidental impact. | Check cutout dimensions, mounting depth, weight limits, viewing angle, and access to serviceable components. |
| Power Input | Typical industrial DC inputs include 9–36 VDC or 12–24 VDC; some systems use AC input through an external or integrated power supply. | Compatible power input helps prevent downtime caused by voltage mismatch or unstable electrical conditions. | Verify nominal voltage, allowable fluctuation, surge protection, grounding, power consumption, and backup-power requirements. |
| Cooling Design | Fanless designs use passive heat dissipation; fan-cooled designs may provide greater thermal capacity for high-performance processors. | Fanless construction can reduce moving-part failure, dust intake, and maintenance, while active cooling may support heavier workloads. | Balance workload, ambient temperature, dust level, acoustic requirements, and maintenance access. |
| Vibration and Shock | Industrial specifications may state vibration resistance in frequency and acceleration ranges, and shock resistance in peak acceleration values. | Appropriate mechanical resistance helps protect the system in vehicles, production lines, machine tools, and heavy equipment areas. | Compare test conditions with actual site vibration, mounting rigidity, transportation requirements, and nearby machinery. |
| Operating System and Software | Systems may support embedded, desktop, or real-time operating environments, subject to hardware driver compatibility. | Software compatibility affects commissioning time, cybersecurity management, application support, and employee training. | Confirm operating-system lifecycle, required drivers, remote-management tools, licensing, and cybersecurity policies. |
| Lifecycle and Serviceability | Industrial equipment is often selected for long-term availability, stable hardware revisions, replaceable storage, and accessible service parts. | A longer support period can reduce redesign costs and simplify maintenance across multiple production sites. | Review availability commitments, spare-part strategy, warranty terms, repair procedures, and remote technical support. |
| Compliance and Testing | Depending on the market and application, relevant requirements may include electromagnetic compatibility, electrical safety, environmental testing, and hazardous-area certification. | Documented compliance reduces project risk and supports approval for installation in regulated or safety-sensitive environments. | Identify applicable local regulations, site standards, test reports, certificates, and installation restrictions before purchase. |
