Main Features and Advantages

• High Fault – Tolerance: The TRICONEX AI3351 adopts a triple – module redundancy structure (TMR), which consists of three identical sub – circuits. Each circuit independently executes a certain degree of control, enabling the module to withstand harsh industrial environments and ensuring high – reliability operation even in the event of a partial circuit failure1.
• On – Site Installability: It allows for online installation and maintenance at the module level without affecting the on – site wiring, which significantly reduces the downtime for system maintenance and improves the maintainability of the equipment1.
• Module Expandability: It supports up to 118 I/O modules (both analog and digital) and optional communication modules, providing strong scalability for the system and meeting the needs of different – scale industrial control applications1.
• Remote Communication Capability: The communication module can be connected to Modbus hosts and slaves, or to distributed control systems (DCS) such as Foxboro and Honeywell, other Tricons in the peer – to – peer network, and external hosts in the TCP/IP network. It can also support remote I/O modules up to 12 kilometers away from the host, facilitating the realization of remote monitoring and control of industrial automation systems1.
• Intelligent Functions: The intelligent functions in the input and output modules relieve the workload of the main processor. Each input/output module is equipped with three microprocessors, which can perform tasks such as signal filtering, fault diagnosis, and data processing, improving the overall performance and efficiency of the system1.
