TRICONEX DI-3506X Digital Input Module

• High reliability: Adopts Triple Modular Redundancy (TMR) structure. Even if one of the channels fails, the other two normal channels can still ensure the normal operation of the system, thus ensuring high availability of the system.
• Flexible configuration: Supports multiple input types and can be flexibly configured according to different application requirements, adapting to various complex on-site environments and process requirements.
• Powerful diagnostic function: Equipped with comprehensive online diagnostic functions, which can quickly detect and isolate faults, helping maintenance personnel find problems in a timely manner and carry out repairs, reducing system downtime.
• Hot standby support: Supports hot standby function, enabling maintenance and replacement of modules without interrupting system operation, improving the maintainability and stability of the system.
• Good compatibility: Compatible with other modules of the Triconex system, easy to integrate into the entire safety instrumented system to achieve seamless connection and ensure the overall performance of the system.

• Signal reception: The module receives digital signals from field devices through dedicated input channels. These signals can be switching signals, pulse signals, etc.
• Signal processing: Processes the received digital signals, including signal filtering, level conversion, logic judgment, etc., to ensure the accuracy and stability of the signals.
• Signal transmission: Transmits the processed digital signals to other modules of the Triconex safety instrumented system, such as controller modules, for subsequent logical operations and control decisions.

• Petrochemical industry: Used for safety interlock control in petroleum refining and chemical production processes, such as start-stop control of pumps and valves, over-limit protection of reactor temperature and pressure, etc.
• Electric power industry: In places such as power plants and substations, it is used for protection and control of power systems, such as generator protection, transformer differential protection, line overcurrent protection, etc.
• Nuclear power industry: In nuclear power plants, it is used for safety monitoring and control of nuclear reactors to ensure their safe operation, such as emergency shutdown control of reactors, fault protection of cooling systems, etc.
