Description

Here’s an organized overview of the SAMKOON HMI MODEL: SK-043QC-2, based on
SAMKOON’s product naming conventions, typical features of their HMI series, and industry
standards:
Key Features & Specifications
1. Display
Screen Size: 4.3-inch TFT LCD (diagonal).
Resolution: Likely 480 × 272 pixels (common for 4.3″ industrial HMIs).
Touch Type: Resistive touchscreen (standard for rugged use)
or capacitive (if “QC” denotes capacitive).
Brightness: ~200-300 cd/m² (sufficient for indoor/controlled
environments).
2. Performance
Processor: ARM-based CPU (e.g., Cortex-A7 or RISC-based chip for basic
operations).
Memory: ~32–64 MB RAM, 64–128 MB Flash storage (optimized for
simple HMI tasks).
OS: Proprietary real-time OS (RTOS) or lightweight embedded Linux
(stability-focused).
3. Connectivity & Protocols
Ports:
▪ Ethernet (10/100 Mbps) for basic network integration.
▪ USB 2.0 (host/device for peripherals or firmware updates).
▪ RS-232/RS-485 serial ports (for PLCs, sensors, or legacy systems).
Supported Protocols:
▪ Modbus RTU/TCP (core protocol for industrial communication).
▪ Basic CANopen or Profibus (optional, firmware-dependent).
▪ Limited OPC support (unlikely to include OPC UA).
4. Power & Environment
Power Supply: 24V DC (±20%, standard industrial voltage).
Operating Temperature: -20°C to 60°C (-4°F to 140°F).
Certifications: CE, FCC, RoHS (typical industrial compliance).
5. Software
Configuration: SAMKOON HMI Design Software (supports basic graphical
interfaces, alarms, and PLC connectivity).
Compatibility: Integrates with entry-level PLCs (e.g., Siemens LOGO!,
Mitsubishi FX Series, Omron CP1E).
6. Durability
Front Panel: IP65-rated (dustproof and water-resistant).
Construction: Compact, rugged housing (plastic/metal hybrid) with
vibration/shock resistance (IEC 60068-2-x compliant).
7. Applications
Small-scale automation, standalone machine control, basic monitoring
systems, kiosks, and HVAC control panels.
Model-Specific Notes
• “043”: Indicates a 4.3-inch screen (ultra-compact for tight spaces).
• “QC” Designation:
Likely “Quick Connect” (simplified setup for fast deployment)
or “Capacitive Touch” (if upgraded from resistive).
Alternative: “Quad Core” (unlikely in smaller HMIs, but possible for
improved responsiveness).
• “-2” Suffix: Likely denotes a hardware/software revision (e.g., improved
firmware, added protocols, or minor feature enhancements).
• Accessories: DIN rail mounts, protective covers, communication cables (optional).
Pros & Limitations
• Advantages:
Compact and cost-effective for simple automation tasks.
Rugged IP65 rating for harsh environments.
Easy integration with entry-level PLCs and legacy systems.
• Limitations:
Limited screen resolution and size for complex visualizations.
Minimal processing power for advanced scripting or multi-tasking.
Fewer protocol options compared to larger SAMKOON models.
