Product Overview

The Triconex 8110 serves as the primary structural and communication foundation for the Tricon™ safety instrumented system (SIS). This High Density Main Chassis is engineered to house the core processing power and critical I/O modules required for fault-tolerant industrial automation. As the central hub of a Triple Modular Redundant (TMR) configuration, the 8110 provides the backplane connectivity necessary for localized 2-out-of-3 voting and high-speed data synchronization. Designed for mission-critical reliability, this chassis facilitates the integration of main processors, power supplies, and communication interfaces, ensuring that safety logic is executed without interruption in the world’s most demanding process environments.

Primary Industrial Deployments

The 8110 High Density Chassis is the preferred starting point for safety systems in high-risk sectors:

Oil and Gas RefiningActing as the centralized control rack for refinery-wide Emergency Shutdown (ESD) systems. Its rugged design ensures the safety logic remains active during seismic events or electrical disturbances common in heavy upstream and downstream operations.

Chemical and Petrochemical ProcessingHousing the TMR modules that monitor volatile reaction parameters. The 8110 provides the reliable communication bus needed to shut down processes safely before hazardous thresholds are reached.

Utility-Scale Power GenerationServing as the safety backbone for burner management systems (BMS) and turbine overspeed protection. The chassis allows for hot-swapping modules, ensuring that power plants maintain high availability without de-energizing the safety loop for maintenance.

Nuclear Safety SystemsUtilized in reactor protection and auxiliary safety loops where a hardware failure cannot be permitted to compromise the safety perimeter. The 8110's diagnostic depth and physical security keyswitch meet strict regulatory oversight requirements.

Mining and Mineral ExtractionProviding a stable mounting platform for safety controllers in remote, harsh environments. Its expansion bus capabilities allow the safety network to grow alongside the facility’s output without requiring a total system overhaul.
