Product Performance

Adopting a high-performance processor with fast instruction execution speed, it can efficiently handle complex logic control and process control tasks, ensuring real-time system response.

Conformal coating design combined with wide temperature adaptability can resist moisture, dust and other pollutants, and operate stably in harsh industrial environments with vibration and shock.

Modular architecture supports flexible expansion, and can be matched with digital, analog I/O modules and communication modules on demand to adapt to automation systems of different scales.

Supports multi-industrial protocols and cross-network communication, and can be seamlessly integrated with HMI, SCADA systems, inverters and other equipment to achieve data interconnection.

Equipped with complete fault diagnosis and alarm functions, it can quickly locate fault points with software, simplifying operation and maintenance processes and reducing maintenance costs.

Supports redundant configuration design, which can build a highly reliable control system, avoid system shutdown caused by single point of failure, and improve production continuity.

Compatible with multiple programming languages, including ladder diagram, function block diagram, etc., to meet different programming habits and shorten project development and debugging cycles.

Excellent electrical isolation performance, effectively resisting electromagnetic interference in industrial fields, ensuring signal transmission integrity and control accuracy.
