Function and Features
High performance color touch screen: 7-inch TFT display, supports gesture operation, real-time trend chart, alarm management, and multilingual interface (Chinese/English/German/French, etc.)
Enhanced I/O system: supports more analog/discrete I/O points, can directly connect RTD and thermocouple temperature signals, reducing the need for external transmitters
Dual Ethernet architecture: supports redundant network connections, Modbus TCP/IP, OPC UA protocols, seamlessly integrated into modern DCS/SCADA systems
Built in data logger: 2GB storage space, capable of recording operational trends, alarm events, and operation logs for several months, supporting USB export
Advanced control algorithms: In addition to standard PID, support model predictive control (MPC), adaptive control, and anti surge protection algorithms
Network security function: supports user permission management, operation audit logs, network firewall function, in compliance with IEC 62443 industrial network security standard
Flexible scalability: Remote I/O modules can be connected through CANopen bus, expanding to hundreds of I/O points
