TRICONEX 8110

Description

Introduction to the TRICONEX 8110

Product Description

The TRICONEX 8110 is a critical power supply module for the Triconex Tricon safety instrumented system (SIS), a high-integrity controller platform from the former Triconex company (now part of Schneider Electric). This module is responsible for converting plant AC or DC power to the precise, regulated DC voltages required to operate the Tricon main processor, I/O modules, and communication cards within a single chassis. The TRICONEX 8110 is engineered with the same focus on fault tolerance and reliability as the logic solvers it supports, ensuring a clean and continuous power source for mission-critical safety functions. It is a hot-swappable, redundant component, allowing for maintenance or replacement without interrupting the operation of the safety system. The proper functioning of the 8110 is foundational to the availability and integrity of the entire Tricon safety loop.

Product Parameters

• Product Series: Triconex Tricon Safety System

• Model: 8110

• Module Type: Power Supply Module (PSM)

• Input Voltage: Typically accepts a wide range of AC (e.g., 120/230VAC) and/or DC input voltages, configurable.

• Output Voltage: Provides the specific DC voltage rails (e.g., +5V, +/-12V) required by the Tricon V9 or V10 chassis backplane.

• Redundancy: Designed to be installed in a redundant pair (N+1) within the same chassis for fault tolerance.

• Hot Swap Support: Fully hot-swappable; a module can be removed and inserted while the chassis is powered.

• Status Indicators: Features comprehensive LED indicators for power status, fault conditions, and redundancy health.

• Certifications: Designed and certified for use in safety systems up to SIL 3 (IEC 61508/61511).

Advantages and Features

The primary advantage of the TRICONEX 8110 is its seamless integration and fault-tolerant design within the Tricon ecosystem. Its key feature is support for true, bumpless hot-swap redundancy, which maximizes system uptime by allowing a failed power supply to be replaced without any shutdown or disruption to the safety controller. The module includes extensive diagnostics that monitor its own health and the status of the power source, providing early warning of potential issues. Its robust design ensures stable operation under varying line voltages and in harsh industrial environments. The TRICONEX 8110 simplifies maintenance and system design by being a purpose-built, fully compatible component of the Tricon platform.

Application Cases in Industry

This power supply module is deployed wherever a Tricon safety system is used for critical process safeguarding. In oil and gas facilities, it powers systems providing Emergency Shutdown (ESD), Fire & Gas (F&G) detection, and Turbomachinery Control. In petrochemical and refining plants, the TRICONEX 8110 supports safety systems for reactor shutdown, burner management, and pressure protection. Within power generation, it is used in boiler protection systems and turbine overspeed protection. It is also a standard component in safety systems for offshore platforms, pipelines, and chemical processing where high availability and safety integrity are non-negotiable.

Comparison with Competing Products

Competing products are power supply modules from other safety system vendors, such as HIMA (for HIMatrix) or Emerson (for DeltaV SIS). The TRICONEX 8110 is not a generic power supply; its value lies in its certified, tested, and guaranteed interoperability with the triple-modular redundant (TMR) architecture of the Tricon controller. While third-party power solutions might physically fit, they lack the formal validation, integrated diagnostics, and guaranteed fault-response characteristics required for a SIL-rated safety system. The 8110 is an integral part of the validated Tricon system, offering peace of mind that the entire safety loop, from power input to logic output, is designed to fail safely.

Selection Suggestions and Precautions

Selection of the TRICONEX 8110 is determined by the specific Tricon chassis model (e.g., V9, V10) and the system’s power budget. It is mandatory to configure it in a redundant pair for any critical safety application to achieve the required availability. The input voltage configuration (jumper or terminal settings) must be carefully set to match the plant’s supply voltage. Ensure the chassis has adequate cooling as per specifications for the combined load of all modules, including the power supplies.

Precautions:

• Installation and maintenance must be performed by personnel trained on Tricon systems and in accordance with the site’s safety work procedures.

• Always follow the precise sequence for hot-swapping the 8110 module as described in the official manual to prevent arcing or backplane damage.

• Verify that the input power source is properly fused and isolated according to local electrical codes.

• In redundant configurations, do not remove both power supply modules simultaneously.

• The use of non-Triconex certified power supplies in a Tricon chassis can invalidate the safety certification of the entire system and introduce unpredictable failure modes.
