Triconex 400093-346 – Tricon Safety Controller Processor Module

In stock

Product Introduction:
The Triconex 400093-346 is a high-capacity processor module for the Tricon safety system. The “346” designation indicates this processor has 2 MB of user memory, significantly more than the 510 configuration (512 KB). This extra memory is essential for large, complex safety applications that require extensive logic, many function blocks, large data tables, and multiple communication interfaces. Examples include large refinery ESD systems, integrated fire and gas systems, and complex burner management systems with dozens of burners. Like all Tricon processors, it is triple modular redundant with 2-out-of-3 voting, SIL 3 certified, and capable of executing deterministic safety logic at speeds up to 10ms scan time.

Functional Features:
2 MB Memory: Four times the memory of the 510 configuration, allowing complex applications with hundreds of function blocks and large data arrays.
Large I/O Capacity: Supports up to 960 I/O points, making it suitable for plant-wide safety systems.
SIL 3 Certified: Same highest safety certification as all Tricon processors.
Online Logic Changes: Application logic can be modified and downloaded while the system is running, minimizing downtime for large plants.
Extended Diagnostics: More memory allows for more extensive diagnostic buffers, storing up to 10,000 events for post-incident analysis.
Multiple Communication Modules: Can support multiple 9753, 9761, and 9771 communication modules simultaneously for integration with multiple DCS systems.

Application Scenarios:
Large Refinery ESD: Controls the emergency shutdown for an entire refinery with hundreds of I/O points and complex logic.
Integrated FGS: Manages a combined Fire and Gas System for a large oil and gas platform with hundreds of detectors and outputs.
Complex Burner Management: Controls dozens of burners in a large power plant boiler with individual flame monitoring and sequencing.
Plant-Wide Safety: Serves as the central safety controller for an entire chemical complex with multiple process units.
