Triconex 8310 Multi-Version Redundant Power Supply Module, 175W High-Temp Resilient TMR Power Unit for Tricon SIS Main & Remote Chassis

Triconex 8310 175W Multi-Version Fault-Tolerant Power Supply Module for Tricon SIS Chassis Power Distribution

Triconex 8310 is a high-performance modular power supply unit in the Triconex 8300 power series, serving as a complementary and differentiated model to the 8300 power module. Optimized for universal and high-temperature SIS chassis power supply scenarios, the 8310 features diversified voltage version configurations and standardized 175W stable power output, perfectly adapting to the power load demands of medium-density Tricon controller and I/O racks. Adhering to Tricon’s exclusive TMR safety power design and industrial-grade anti-aging circuit layout, this module eliminates power-related single-point failures and provides long-term 24/7 uninterrupted power guarantee for core safety instrumented systems.

1. Multi-Version Wide-Range Voltage Input Specifications

Diversified AC/DC Input Configuration Options

Distinct from the single fixed-range design of conventional power modules, Triconex 8310 supports three mainstream industrial input versions including 24VDC, 115VAC and 230VAC, fully covering global factory power distribution standards. The DC input version adapts to low-voltage industrial power supply systems, while dual AC versions fit conventional civil and industrial high-voltage power grids. This multi-version design enables flexible model selection according to on-site power conditions, eliminating the need for external voltage conversion equipment and simplifying overall SIS power system layout.

Stable Wide-Voltage Adaptation Performance

Each version of the 8310 module features optimized wide-voltage tolerance, effectively resisting common industrial grid fluctuations, transient surge interference and unbalanced voltage output. The built-in voltage stabilization circuit automatically calibrates input deviation, ensuring consistent internal power conversion efficiency and stable DC output quality. It supports a minimum 240W external power supply matching requirement, fully meeting the full-load startup and continuous operation power demand of medium-density SIS I/O and communication module groups.

2. 175W Rated Power & Standardized Output Performance

High-Stability 175W Continuous Power Output

Triconex 8310 delivers a steady 175W rated power output at 60°C industrial operating temperature, with reliable load capacity for long-term full-load operation. The precise power matching design is tailored for standard Tricon main chassis and remote expansion racks, perfectly driving common combinations of CPU modules, analog/digital I/O units and network communication modules. Compared with high-power modules, the 175W compact power design avoids redundant power waste and reduces overall system operating costs for medium-scale SIS projects.

Standard Fuse Protection & Stable Load Adaptation

Equipped with a built-in 5A time-delay fuse, the module provides accurate overcurrent protection for internal circuits and rear-end load equipment. The delay-type fuse design effectively avoids false triggering caused by instantaneous current surge during equipment startup, ensuring stable system startup and continuous operation. It supports flexible load matching and multi-module parallel redundant deployment, adapting to diversified load demands of different scale SIS chassis configurations.

3. High-Temperature Resilient & Industrial-Grade Durability

-40°C to +70°C Ultra-Wide Temperature Operation

Triconex 8310 features an enhanced high-temperature resistance design, supporting stable continuous operation in an ultra-wide industrial temperature range from -40°C to +70°C. It maintains complete power output efficiency and voltage stabilization accuracy even in high-temperature cabinet heat accumulation and low-temperature outdoor field environments. The temperature-resistant component layout solves the performance attenuation problem of ordinary power modules in extreme temperature scenarios, greatly improving environmental adaptability of SIS power systems.

Rugged Harsh Environment Adaptability

With industrial-grade sealing and anti-vibration structure, the module resists industrial dust accumulation, 5%–95% non-condensing humidity and mechanical vibration during long-term operation. The optimized anti-aging circuit design slows down component attenuation under harsh working conditions, extending the overall service life of the power unit. It fully adapts to rigorous working environments of petrochemical workshops, power plant equipment rooms and offshore industrial platforms.

4. TMR Redundant Architecture & Full-Function Safety Protection

Dual Redundant Hot-Standby Power Mechanism

Following Tricon TMR safety system standards, Triconex 8310 supports dual-module hot-standby redundant deployment. Two independent 8310 power units operate in parallel, achieving seamless automatic switching in case of single module failure, overheating or output abnormality. The redundant power architecture completely eliminates system shutdown risks caused by single power unit faults, ensuring zero interruption of SIS safety logic operation and field signal monitoring.

Comprehensive Circuit Safety Protection

Integrating overcurrent, overvoltage, short-circuit and overheating multi-dimensional protection mechanisms, the module automatically triggers power limiting and fault locking when abnormal load or circuit faults occur. The intelligent protection strategy effectively isolates fault points, protects high-precision SIS core modules from electrical damage, and supports transient fault self-recovery, reducing manual maintenance frequency and improving system operational stability.

5. Real-Time Diagnostics & Hot-Swap Maintenance

Intelligent Power Status Monitoring & Alarm Feedback

Triconex 8310 supports real-time background diagnosis of input voltage, output power, operating temperature and circuit status. Front panel LED indicators intuitively display power supply operation, standby state and fault alarm information for rapid on-site inspection. It is equipped with independent alarm contacts, which can feed back power fault signals to the upper monitoring system in real time, realizing remote early warning and fault judgment.

Online Hot-Swap Replacement Support

Compatible with standard Tricon chassis hot-swap technology, the module supports online disassembly and replacement without shutting down the chassis or suspending SIS safety operation. The non-stop maintenance feature eliminates unplanned production shutdown losses caused by power module maintenance, ensuring continuous and stable operation of industrial critical safety control systems.

6. Safety Certification & Target Industrial Applications

Triconex 8310 complies with IEC 61508 functional safety standards and meets SIL3 system-level safety integrity requirements, with authoritative CE and UL hazardous area certifications. It is widely applied in medium-scale Tricon SIS main chassis and remote expansion racks in petrochemical refining, natural gas processing, thermal power generation and offshore platform industries. It provides reliable redundant power support for core safety systems such as ESD emergency shutdown, fire & gas detection and process interlock control loops.
