8400 | Triconex Controller Module for TMR SIS Platforms

Product Description

Overview

The Triconex 8400 is the central processor module for Triconex Safety Instrumented Systems (SIS).
It executes all safety logic and coordinates I/O modules in mission-critical industrial environments.
Moreover, the module features Triple Modular Redundancy (TMR) to ensure continuous operation without single-point failures.
It is engineered for high-hazard industries, providing safe shutdown, fire & gas protection, and high-integrity pressure protection.
