Description
Product Details
The TC-4000-S is a processor card designed to execute the control program for a safety-critical application.In a Triconex TMR system,three of these modules operate in parallel,independently processing inputs and executing the control logic.The modules then perform a voting process to determine the correct output,ensuring that a failure in one processor will not affect the system’s overall integrity or cause a spurious trip.This redundancy provides extremely high reliability and availability.
Key Features and Functionality
The main function of the TC-4000-S is to provide a fault-tolerant control solution.It is a workhorse for safety applications,designed for continuous and reliable operation in harsh industrial environments.Its key features include high-speed processing for deterministic control,robust diagnostics to detect and report internal faults,and the ability to operate as one of three redundant processors in a TMR chassis.The module also manages communication with the I/O modules and external devices,serving as the central intelligence of the safety system.
Application and Maintenance
The TC-4000-S is primarily used in industries where safety is paramount,such as oil and gas,petrochemicals,nuclear power,and refining.It is a vital component in emergency shutdown systems(ESD),fire and gas systems,and burner management systems(BMS).As a legacy part,the TC-4000-S is no longer in active production.Maintenance for these modules is focused on replacement in the event of a failure,and sourcing reliable,tested units from specialized industrial parts suppliers is a key part of any maintenance strategy.
