Product Short Description
Overview:
The TRICONEX 8312 is a 230 VAC input, 175 W redundant power supply module designed for the Schneider Electric Triconex Tricon TMR (Triple Modular Redundancy) Safety Instrumented System. It converts 230 VAC mains power into a stable 24 VDC (nominally 6.5 VDC chassis bus) supply for the Tricon chassis backplane, powering processors, I/O modules, and communication modules. It is built for SIL 3-rated ESD, F&G, and BMS applications.

Key Features:
-
1+1 redundancy with < 10 ms seamless transfer ensures zero downtime
-
Wide-range 100–240 VAC input simplifies global spare parts logistics
-
Comprehensive electrical protection (OVP, OCP, OTP, SCP)
-
3000 VAC isolation prevents external surge propagation to backplane
-
Hot-swappable for online maintenance
-
N+1 parallel capability – multiple units share load; single failure causes no interruption
-
SIL 3 certified for safety-related power supply
Application Scenarios:
Petrochemical ESD (Emergency Shutdown) systems, Fire & Gas (F&G) systems, oil & gas extraction platforms, power plant protection systems, BMS (Burner Management Systems).
Installation & Notes:
Install in the Tricon chassis dedicated power slot. For full redundancy, populate two slots with 8312 modules. The module can be hot-swapped, but verify the redundant unit is healthy before removing a faulty one. Ensure mains wiring complies with local electrical codes; the 2.5 A time-delay fuse protects against input-side faults. Monitor the TEMP and BATT LOW LEDs during operation – an illuminated TEMP LED indicates internal temperature > 83 °C, suggesting inadequate ventilation.
