Description
TRICONEX 8312 Power Module
Product Overview:
The TRICONEX 8312 is a highly reliable, redundant power supply module designed specifically for Tricon safety instrumented system (SIS) chassis. It is the primary source of conditioned, regulated power for all electronic modules within a Tricon rack, including the main processors, I/O modules, and communication modules. Its fundamental purpose is to ensure uninterrupted and clean power delivery, which is a critical foundation for the fault-tolerant operation of the entire Triple Modular Redundant (TMR) system. The failure of system power is a common cause for safety system activation, making the TRICONEX 8312‘s reliability paramount.
Key Features and Advantages:
N+1 Redundant Configuration:
The TRICONEX 8312 is designed to be installed in a redundant pair (or more) within a chassis. In a standard N+1 configuration, the modules share the total system load. If one power supply fails, the remaining module(s) can instantly and seamlessly assume the entire electrical load without any interruption to the system’s operation. This redundancy is essential for meeting the high availability requirements of critical safety systems, ensuring there is no single point of failure in the power subsystem.
Wide-Range Input and Hot-Swap Capability:
The module accepts a wide range of input voltages (typically 85-264 V AC or 88-300 V DC), allowing it to be deployed in various global electrical environments without the need for external transformers. It supports true hot-swap replacement. A faulty TRICONEX 8312 can be removed and a new module inserted while the system remains powered on and fully operational, enabling maintenance without requiring a process shutdown or transferring the safety system to a bypass mode.
Conditioned and Isolated Output:
The module provides tightly regulated, low-noise DC output voltages (typically +5V and +/-12V or +24V) to the Tricon backplane. This clean, stable power is crucial for the precise operation of sensitive digital and analog circuits within the TMR modules. The power supply also provides electrical isolation between the input power source and the internal system electronics, protecting the Tricon system from transients, spikes, and noise on the plant power lines.
Comprehensive Status Monitoring and Diagnostics:
The TRICONEX 8312 features extensive self-diagnostics and status reporting. It monitors its own health, including input voltage presence, output voltage levels, internal temperature, and load sharing status. This diagnostic information is communicated to the Tricon main processor module. Any fault condition, such as a loss of input power, over-temperature, or output failure, is immediately reported to the control system, allowing for prompt maintenance action.

Application Areas:
The TRICONEX 8312 is deployed in every Tricon safety system chassis across all critical industries. Its role is foundational, powering Safety Instrumented Systems (SIS) for Emergency Shutdown (ESD) in offshore platforms and refineries, Fire & Gas (F&G) detection and mitigation systems, Turbomachinery Control (TMC), and Burner Management Systems (BMS) in power plants and industrial furnaces. Any application where a Tricon system is installed to perform a safety function relies on the continuous, fault-tolerant power provided by this module.
