Description

Here’s an organized overview of the SAMKOON HMI MODEL: SK-070QE-G, based on typical
features of SAMKOON’s HMI series, industry standards, and model-specific indicators (e.g.,
“070” for screen size, “QE-G” designation
Key Features & Specifications
1. Display
Screen Size: 7-inch TFT LCD (diagonal).
Resolution: Likely 800 × 480 pixels (common for 7″ industrial HMIs).
Touch Type: Resistive touchscreen (supports glove/object input) or
capacitive (if updated).
Brightness: ~250-350 cd/m² (suitable for indoor/industrial lighting).
2. Performance
Processor: ARM-based CPU (e.g., Cortex-A7/A8 for mid-range
performance).
Memory: ~64–128 MB RAM, 128–256 MB Flash storage (sufficient for
basic to moderate HMI tasks).
OS: Proprietary RTOS or lightweight embedded OS (optimized for
reliability).
3. Connectivity & Protocols
Ports:
▪ Ethernet (10/100 Mbps) for network integration.
▪ USB 2.0 (host/device for data transfer or peripheral connection).
▪ RS-232/RS-485 serial ports (for PLCs, sensors, or legacy devices).
Supported Protocols:
▪ Modbus RTU/TCP (industrial standard).
▪ 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%, standard industrial voltage).
Operating Temperature: -20°C to 60°C (-4°F to 140°F).
Certifications: CE, FCC, RoHS (typical compliance).
5. Software
Configuration: SAMKOON HMI Design Software (supports ladder logic,
scripting, and graphical interfaces).
Compatibility: Works with major PLC brands (Siemens, Mitsubishi,
Omron) and SCADA systems.
6. Durability
Front Panel: IP65-rated (dustproof and water-resistant).
Construction: Rugged metal/plastic housing for vibration/shock resistance
(meets IEC 60068-2-x standards).
7. Applications
Machine control, small-scale automation, HVAC systems, packaging
machinery.
Model-Specific Notes
• “070”: Indicates a 7-inch screen (compact size for space-constrained
installations).
• “QE-G” Designation:
QE: May denote “Quick Ethernet” (emphasizing network connectivity) or a
specific firmware variant.
G: Could signify “Glass Front” (enhanced durability) or a regional/custom
variant.
• Accessories: DIN rail/mounting brackets, communication cables (optional).
Advantages & Limitations
• Pros: Compact design, cost-effective for small applications, robust industrial
certifications.
• Cons: Limited processing power for complex visualization; smaller screen may
reduce multi-window usability.
