Description

Here’s a structured overview of the SAMKOON HMI MODEL: SK-070QC-1, based on
SAMKOON’s product naming conventions, typical features of their HMI series, and industry
standards:
Key Features & Specifications
1. Display
Screen Size: 7-inch TFT LCD (diagonal).
Resolution: Likely 800 × 480 pixels (standard for 7″ industrial HMIs).
Touch Type: Resistive touchscreen (common for industrial use) or
capacitive (if “QC” denotes capacitive).
Brightness: ~250-350 cd/m² (suitable for indoor/industrial environments).
2. Performance
Processor: ARM-based CPU (e.g., Cortex-A7/A8 for mid-tier performance).
Memory: ~64–128 MB RAM, 128–256 MB Flash storage (sufficient for
basic to moderate HMI applications).
OS: Proprietary real-time OS or lightweight embedded OS (optimized for
stability).
3. Connectivity & Protocols
Ports:
▪ Ethernet (10/100 Mbps) for network integration.
▪ USB 2.0 (host/device for peripherals or data transfer).
▪ RS-232/RS-485 serial ports (for PLCs, sensors, or legacy devices).
Supported Protocols:
▪ Modbus RTU/TCP (core industrial protocol).
▪ CANopen, Profibus (optional, depending on firmware).
▪ Basic OPC support (may lack OPC UA in entry-level models).
4. Power & Environment
Power Supply: 24V DC (±20%, industrial standard).
Operating Temperature: -20°C to 60°C (-4°F to 140°F).
Certifications: CE, FCC, RoHS (typical for industrial electronics).
5. Software
Configuration: SAMKOON HMI Design Software (supports drag-and-drop
GUI creation, scripting, and PLC integration).
Compatibility: Works with PLCs from Siemens, Mitsubishi, Omron, and
others.
6. Durability
Front Panel: IP65-rated (dustproof and water-resistant).
Construction: Rugged housing (metal/plastic blend) for vibration/shock
resistance (IEC 60068-2-x compliant).
7. Applications
Machine control, small-scale automation, HVAC systems, packaging lines,
and process monitoring.
Model-Specific Notes
• “070”: Indicates a 7-inch display (compact size for space-limited installations).
• “QC” Designation:
Likely “Quick Connect” (emphasizing simplified setup) or “Quad Core” (if
upgraded processor).
Alternatively, “Capacitive Touch” if the “C” differentiates touchscreen
type (e.g., capacitive vs. resistive).
• “-1” Suffix: May denote a hardware revision, regional variant, or minor feature
upgrade.
• Accessories: DIN rail mounts, protective films, communication cables (often sold
separately).
Pros & Limitations
• Advantages:
Compact and cost-effective for small-to-medium automation tasks.
Rugged design with IP65 protection.
Multi-protocol support for flexible integration.
• Limitations:
Limited processing power for complex visualizations or multi-tasking.
Smaller screen may restrict data visibility in dense applications.
