TRICONEX 2000418: 24V DC Power Supply for Tricon Safety System

Product Description

The TRICONEX 2000418 is a dedicated 24V DC power supply module for the Tricon safety instrumented system (SIS). This module provides conditioned and reliable power to Tricon input/output (I/O) modules and other system accessories. The TRICONEX 2000418 converts an AC input voltage to a stable, regulated 24V DC output, serving as the primary or auxiliary power source for field devices and sensors connected to the Tricon system. Its design emphasizes safety, reliability, and compatibility within the critical architecture of a safety shutdown system. The consistent performance of the TRICONEX 2000418 is essential for ensuring that all safety-critical I/O modules receive clean power, which is fundamental for accurate signal acquisition and control.

Advantages and Features

The key advantage of the TRICONEX 2000418 is its engineered reliability and compatibility within the Tricon safety ecosystem. It provides a clean, stable DC power source, which minimizes electrical noise that could interfere with sensitive analog and digital signals in the safety loop. The module is designed for ease of integration, with clear terminal labeling and a compact form factor. Its robust construction ensures long-term performance in industrial environments. Using the OEM TRICONEX 2000418 power supply reduces integration risk and ensures compliance with the system’s overall design specifications for safety and performance.

Application Cases in Various Fields

This power supply is used to power remote I/O racks or field device loops within Tricon safety systems. In Oil & Gas facilities, the TRICONEX 2000418 might power a cabinet of I/O modules in a remote wellhead or compressor station that is part of an Emergency Shutdown (ESD) system. Within Chemical Plants, it could supply power to gas detectors and solenoid valves interfaced with the safety controller. For Power Generation, it may energize I/O modules for burner management or turbine trip systems. It is essential wherever a dedicated, reliable 24V DC source is needed for the field-side circuits of a Tricon SIS.

Comparisons with Competing Products

Compared to generic 24V DC industrial power supplies, the TRICONEX 2000418 is selected primarily for its vendor endorsement and guaranteed compatibility within Tricon projects. Competing safety system vendors like HIMA or ABB also recommend or supply specific power modules. While a generic supply with equivalent electrical specifications might function, the TRICONEX 2000418 offers the assurance of being tested and validated for use in a safety system environment, often simplifying engineering approval and maintenance documentation. Its value is in risk reduction and support within the Tricon product lifecycle.

Selection Suggestions and Precautions

1. Load Calculation: Before selection, calculate the total 24V DC current required by all connected I/O modules, isolators, and any two-wire field transmitters powered by the system. Ensure the TRICONEX 2000418‘s current rating exceeds this total with a safety margin (typically 20-30%).
2. Input Voltage Verification: Confirm the available AC line voltage at the installation site matches the input range of the TRICONEX 2000418 (e.g., 120V AC vs. 240V AC).
3. Safety System Grounding: Follow the Tricon system grounding guidelines meticulously. Proper grounding of the DC power supply’s output is critical for noise immunity and safety. Incorrect grounding can introduce noise or create ground loops.
4. Fusing and Protection: Even with internal protections, it is good practice to install an appropriately rated fuse or circuit breaker on the AC input line feeding the TRICONEX 2000418. For critical loads, consider redundancy.
5. Environmental Conditions: Ensure the power supply is installed in an environment within its specified temperature, humidity, and cleanliness ratings. Adequate ventilation should be provided to prevent overheating, which can reduce the lifespan of the TRICONEX 2000418.
