The SK Series Human-Machine Interfaces (HMI) include two major product lines: the SK-Q-G IoT Series and the SK General Series. The SK-Q-G IoT Series offers robust remote communication capabilities, supporting plug-and-play 4G and Wi-Fi communication modules, and is fully compatible with SK’s self-developed cloud platform, enabling effortless remote operation and maintenance. The SK General Series (non-IoT) features a wide range of models, various interface options, and multi-level password protection. Optional models include waterproof, communication-isolated, and handheld versions to meet specialized application needs.
Powerful IoT Capabilities for Easy Remote O&M
The SK-Q-G IoT Series is available in 4.3″, 7″, 10.2″, and 15.6″ screen sizes and supports both 4G and Wi-Fi modules. Customers can choose communication modules based on their needs and pair them with the HMI hardware.
VNC Function
- Supports real-time data and screen synchronization between the HMI and both PC and mobile devices, enabling users to monitor and control the screen remotely without being physically present.
- Compatible with the SK Cloud 3.0 platform, simplifying multi-level control structures.
Remote Transparent Transmission
- Enables remote PLC program upload/download and remote monitoring, solving the issue of engineers being unable to arrive on-site in time.
Optional Wi-Fi/4G IoT Expansion Modules
- Flexible module selection based on usage scenarios, ensuring convenient deployment.
Rich Interfaces & Powerful Communication
- Supports various communication modes (RS232/422/485, Ethernet, Wi-Fi, 4G)
- USB project download and U disk configuration updates supporte
All-Scenario Adaptability
- The SK General Series offers a broad model range with support for RS232/422/485, Ethernet, and USB interfaces.
- Screen sizes range from 3.5″ to 15.6″, with options for high-definition, waterproof screens, handheld teaching pendants, and communication-isolated models to fit diverse application environments.
Precise Touch Experience
- High sensitivity: Resistive/capacitive touch options (depending on model), supports glove operation, response time <10ms.
- Easy calibration: Hardware DIP switch or software key functions for fast calibration, solving touch drift issues.
Intelligent Protocol Matrix
- Multi-protocol support: Compatible with Modbus RTU/ASCII/TCP, CodeSys, RS232/422/485, Ethernet, 4G/Wi-Fi (select models), and major PLC brands (e.g., Mitsubishi, Siemens), covering over 90% of industrial equipment.
- Supports multi-device communication (extended mode) with a single screen to meet complex control scenarios.
Expert for Extreme Environments
- Industrial durability: Operating temperature -20°C to 55°C, storage temperature -30°C to 70°C, dust- and moisture-resistant design for harsh environments.
- Stable performance: Wide voltage input (12VDC~30VDC) and electromagnetic interference resistance (CE certified).
Advanced Security System
The SK Series HMI features banking-level security with triple encryption to safeguard your production line:
- Project file encryption to prevent unauthorized program copying
- Dual-screen lock (dynamic + static) to block unauthorized operations
- 8-level user permission control with traceable critical actions
