Description
Product Overview
The TRICONEX 8311N is a dedicated power supply unit for Tricon triple‑modular‑redundant (TMR) safety instrumented systems. It delivers stable, filtered power to the Tricon chassis, processors and I/O modules. Designed for hot‑swap operation, it allows module replacement online without shutting down the safety system. Built‑in hardware diagnostics monitor input voltage, internal temperature and battery status, reporting failures via front‑panel LED indicators. This unit is widely used for maintenance and spare‑part replacement of legacy Tricon safety systems in process industries.
Series
Tricon SIS Series by TRICONEX. This series adopts triple‑modular redundant (TMR) fault‑tolerant architecture for safety‑critical process control. The 8311N power supply installs in dedicated power slots of Tricon main chassis, works cooperatively with Tricon processor modules and various I/O modules to complete safety interlock and protection functions.
Product Features
- Hot‑swap capable, online replacement without system shutdown, reduces plant downtime risk
- Full‑set front‑panel LED status indicators: PASS, FAIL, ALARM, TEMP, BAT LOW for quick on‑site troubleshooting
