Product Description
Triconex 8400 Low Density Main Chassis
Product Overview
- The Triconex 8400 is a Low Density Main Chassis designed for the Triconex Safety Instrumented System (SIS), part of Schneider Electric’s EcoStruxure Tricon platform. It serves as the primary housing for critical modules, including Main Processors, I/O modules, and communication modules, in safety-critical applications. Built for industries like oil and gas, chemical, and power generation, the 8400 supports the Triple Modular Redundant (TMR) architecture, ensuring high reliability and fault tolerance to meet Safety Integrity Level 3 (SIL3) requirements.
