01What is an Industrial Tablet PC?
An industrial tablet PC is an intelligent terminal for industrial automation scenarios that integrates display, computing, and control. Its main advantages are resistance to harsh environments and multi-interface expandability. Unlike consumer-grade tablets, it features a fully metal reinforced body (Advantech PPC-312T aluminum-magnesium alloy frame), wide voltage power supply design (Siemens SIMATIC IPC 8VA supports 12-24VDC input) and modular expansion slots. Major brands include Advantech and Siemens.
02Key Parameters of Industrial Tablet PCs
·Screen Size: 7 inches to 24 inches, such as Advantech PPC-331W with a 21.5-inch 4K screen
·Processor Performance: Intel Celeron to Xeon
·Protection Level: IP65-IP69K, such as Siemens SIMATIC IPC 8VA reaching IP66 for dust and water resistance
·Operating Temperature: -30℃ to 70℃; Advantech PPC-312T wide temperature model suitable for polar scientific research
·Brightness Range: 500-1500cd/m², such as Siemens outdoor screen with 1200cd/m² visibility in sunlight
·Storage Expansion: 8GB-64GB RAM + 256GB-2TB SSD
·Industrial Interfaces: RS232/485, CAN bus, PoE
03Applicable Scenarios for Industrial Tablet PCs
·Industrial Control: AGV scheduling control center; Advantech PPC-331W supports 5G module
·Warehouse Logistics: PDA scanning and sorting
·Outdoor Operations: Oilfield data collection; Siemens SIMATIC IPC 8VA resistant to salt spray corrosion
·Medical Equipment: CT image processing
·Intelligent Transportation: Vehicle scheduling terminal; Advantech TREK-743 supports vehicle vibration protection
04Common Purchasing Questions for Industrial Tablet PCs
Q1: What is the essential difference from commercial tablets?· Industrial-grade is achieved through shock resistance (100G vibration test), wide temperature operation (Advantech -30℃ cold start), EMC anti-interference certification (Siemens Class A).
Q2: How to choose between IP65 and IP67?· Choose IP65 for workshop dust environments. IP67 is required for food factory washing scenarios.
Q3: Is it necessary to use high-end processor models?· Visual inspection requires i5 or higher, while data collection can use Celeron, such as Advantech PPC-312T.
Q4: Is an external expansion module needed?· Motion control requires PCIe slots, and scanning scenarios should choose M12 aviation connectors, such as Siemens SIMATIC IPC.
Q5: Are maintenance costs high?· Average time between failures (MTBF) ≥ 100,000 hours, such as Advantech PPC series, supports hot-swappable batteries.
05Conclusion
·Product Positioning: The “industrial edge computing center” from data collection to intelligent decision-making
·Key Parameters: Environmental tolerance × computing power configuration × interface expandability determines scenario limits
·Scenario Matching: Heavy protection in harsh environments, real-time control with high computing power, and long battery life in mobile scenarios
·Key Points for Purchase: Reliability certification > modular design > long supply cycle
· Industrial tablet PCs are the “smart fortress” of Industry 4.0. Selection should focus on protection and computing power, distinguishing between fixed and mobile scenarios, and operational maintenance should emphasize expansion interfaces and full lifecycle support!
