The Triconex 7400028-100, also designated as Model 8101, is a robust 15-slot expansion chassis engineered for integration within Triconex Triple Modular Redundancy (TMR) safety systems. This industrial rack provides the necessary physical and electrical infrastructure to expand I/O capacity in demanding environments, including power generation, petrochemical processing, and oil refining. By supporting redundant configurations, this chassis helps maintain high system availability and operational safety.
Features
15-slot capacity for high-density I/O module deployment.
Supports hot-swapping of modules, enabling maintenance without system shutdown.
Passive backplane design to enhance reliability and increase MTBF.
Dual-power rail distribution for support of redundant power supply modules.
Keyed slots to prevent incorrect module installation.
Optimized for high-speed communication with the Main Processor via the I/O expansion bus.
Applications
This expansion chassis is suited for safety-critical applications requiring high-speed data acquisition and redundant control. It is commonly utilized in emergency shutdown systems (ESD), burner management systems (BMS), and critical process control loops where hardware failure must not interrupt the safety function.
