Computers & Tablets

Choosing Between Fixed Industrial Computers and Mobile Rugged Tablets

Your deployment environment dictates the hardware form factor. Fixed workstations, such as panel PCs, are ideal for stationary machinery monitoring and human-machine interface applications. Rugged tablets excel in field diagnostics, inventory management, and mobile inspections where technicians need portable data access.

• Select panel PCs for permanent mounting in control cabinets or production lines.
• Choose rugged tablets with high-ingress protection ratings for mobile field service.
• Ensure compatibility with existing low-voltage wiring systems using standard 18-24 AWG connectors.

Matching Ingress Protection and Thermal Specs to Your Environment

Industrial computing hardware must survive dust, moisture, and extreme temperatures. When installing systems in washdown areas or outdoor locations, look for high IP ratings. You can also protect external connections and auxiliary boards by housing them in dedicated IP65 polycarbonate enclosures.

• Use IP65 rated enclosures to protect external wiring connections from high-pressure water jets and dust.
• Verify the operating temperature range of your computing equipment, especially in unconditioned spaces.
• Install thermoplastic-housed connectors with silicone seals for secure, moisture-resistant connections.

Protecting Communication Ports and Sensitive Electronics from Surges

Industrial computers connect to various sensors, actuators, and power lines that are prone to electrical noise and voltage spikes. Implementing circuit protection on these communication lines is critical to prevent processor damage. Utilize transient voltage suppression (TVS) diodes on data lines to clamp unexpected voltage surges.

• Select TVS diodes from the P6KE series to handle peak pulse power up to 600W on sensitive data lines.
• Match the diode standoff voltage to your system operating voltage to avoid leakage current.
• Use fast-switching Schottky and rectifier diodes like 1N5819 or 1N4007 for reverse-polarity protection on power input lines.
