PC industriel ou PC grand public : 8 différences clés

1. Operating Temperature

Commercial PCs: 0°C, 35°C. Industrial PCs: 0°C, 60°C standard, with wide-temperature models to −40°C, 85°C. India's climate, from cold northern winters to hot foundry floors and outdoor installations in Rajasthan, makes extended temperature ratings essential.

2. Fanless Cooling

Commercial PCs use fans that ingest factory dust, fail from vibration, and require regular maintenance. Industrial PCs use passive heatsink cooling with no moving parts, sealed chassis with no ingress paths.

3. Industrial I/O

Industrial PCs include COM ports (RS-232/422/485), GPIO, CAN bus, and isolated I/O for connecting to PLCs, drives, and sensors. Commercial PCs have only USB, HDMI, and audio, useless for direct field device connectivity.

4. Vibration and Shock Rating

Industrial PCs are tested to IEC 60068 vibration and shock standards. They use solid-state storage with no moving parts, locking connectors, and conformal-coated PCBs. Commercial PCs are not designed for vibration, HDDs fail rapidly, connectors work loose.

5. Product Lifecycle (5 à 10 Years)

A consumer laptop is discontinued in 12 à 18 months. Industrial platforms are maintained in production for 5 à 10 years, critical for manufacturing lines where downtime for a platform redesign is unacceptable.

6. 24/7 Operation Rating

Industrial PCs are designed and stress-tested for continuous 24/7 operation. Commercial PCs are rated for office hours use only.

7. Wide Voltage Input

Industrial PCs accept 9 à 36V DC or 18 à 75V DC input, tolerating the voltage fluctuations common in Indian industrial power supplies. Commercial PCs require clean 230V AC power.

8. Certifications

Industrial PCs carry CE, FCC, RoHS, and often UL/cUL certifications for industrial environments. Commercial products are not certified for industrial installations and may not comply with plant safety requirements.
