Product Details:

TRICONEX 8111 is a TMR expansion chassis built with triple modular redundancy (TMR) architecture for Triconex Tricon safety instrumented systems (SIS). This TMR safety rack is used to expand the I/O capacity of the Tricon system, connecting to the 8110 main chassis via triplicated RS485 I/O bus to add extra I/O modules for larger safety control projects. The Tricon expansion chassis can accommodate up to eight slot sets of I/O modules, and the backplane provides triplicated signal paths to match TMR 2-out-of-3 voting mechanism. The chassis adopts welded cold-rolled steel with black zinc plating for solid mechanical protection and shielding against industrial electromagnetic interference. It reserves redundant power module slots and supports hot swap of all plug-in I/O and communication modules, so maintenance work can be carried out without shutting down the whole safety system. Built-in circuit monitoring tracks backplane bus status and power supply health, and fault alarms will be sent to the Tricon engineering workstation when abnormal conditions occur. Front panel LED indicators display power, bus link and fault status for fast on-site inspection and troubleshooting. Widely applied in oil & gas, petrochemical, chemical and power industries, this TRICONEX 8111 expansion chassis works together with the main chassis to build extended hardware platforms for ESD emergency shutdown, fire and gas detection and burner management safety interlock systems.
