The TRICONEX 4000098-510 is a high-integrity, redundant-capable 24 VDC power supply module designed exclusively for Tricon v10 and v11 safety instrumented systems (SIS) from Schneider Electric (formerly Triconex). As a foundational component of the Triple-Modular Redundant (TMR) architecture, the TRICONEX 4000098-510 ensures uninterrupted, clean power delivery to the main processor, I/O modules, and communication cards within the Tricon chassis—critical for maintaining functional safety in SIL 3 applications. Unlike standard industrial power supplies, this module is engineered to operate in redundant pairs (typically installed in slots 1 and 2), enabling seamless failover without system interruption during maintenance or fault events.
The TRICONEX 4000098-510 integrates deeply with the Tricon’s diagnostic ecosystem, reporting real-time status—including output voltage, current load, temperature, and fault conditions—to the Enhanced Diagnostic Monitor (EDM) and TriStation 1131 engineering workstation. This allows operators to proactively address potential issues before they impact safety logic execution. Widely deployed across oil & gas, chemical processing, power generation, and pharmaceutical facilities, the TRICONEX 4000098-510 exemplifies Triconex’s commitment to reliability, compliance, and operational continuity in the most demanding safety-critical environments.

Main Features and Advantages
Robust redundant power architecture: The TRICONEX 4000098-510 is designed to operate in dual-redundant configuration, where two modules share the load equally. If one fails or is removed for maintenance, the other instantly assumes full load—ensuring zero downtime in safety-critical processes. This N+1 redundancy is fundamental to achieving SIL 3 compliance under IEC 61511.
Advanced diagnostics and monitoring: Unlike conventional PSUs, the TRICONEX 4000098-510 communicates continuously with the Tricon controller via the backplane. It reports precise output voltage, current draw, internal temperature, and fault flags (e.g., overvoltage, undervoltage, fan failure) to EDM software, enabling predictive maintenance and rapid troubleshooting.
Industrial-grade reliability: Built with wide-input AC capability (85–264 VAC), the TRICONEX 4000098-510 tolerates brownouts, surges, and generator transients common in remote or offshore sites. It includes comprehensive protection features—overcurrent, overtemperature, short-circuit, and reverse polarity—all validated under harsh environmental testing.
Seamless integration and hot-swap support: The module slides into the designated power slots (1 and 2) of the Tricon chassis without tools. With proper procedures, it supports hot insertion and removal, minimizing disruption during upgrades or replacements. Firmware and hardware revisions are tracked automatically by the system for audit and compatibility assurance.
Long lifecycle and global support: Despite newer Tricon platforms emerging, the TRICONEX 4000098-510 remains in active production and service due to its prevalence in installed base systems worldwide. Schneider Electric maintains rigorous quality control and long-term availability commitments for such critical spares.
Application Field
The TRICONEX 4000098-510 is indispensable in industries where process safety failures can result in catastrophic consequences. In oil refineries, it powers Triconex emergency shutdown (ESD) systems that monitor reactor pressures and trigger isolation valves during overpressure events—requiring absolute power reliability. On offshore drilling platforms, the TRICONEX 4000098-510 supports fire and gas detection logic solvers that must remain operational despite voltage fluctuations from diesel generators or marine electrical noise.
In chemical plants, the module ensures continuous power to TMR controllers managing toxic material containment interlocks, where even a millisecond of power loss could violate regulatory compliance. Similarly, in liquefied natural gas (LNG) terminals, redundant TRICONEX 4000098-510 units safeguard cryogenic pump control systems operating at -162°C, where maintenance access is limited and system uptime is non-negotiable.
Beyond process industries, the TRICONEX 4000098-510 is also used in nuclear auxiliary safety systems, pharmaceutical batch reactors, and hydroelectric dam gate controls—anywhere functional safety, regulatory adherence (e.g., OSHA PSM, IEC 61511), and 24/7 availability converge. Its role may be “behind the scenes,” but the TRICONEX 4000098-510 is truly the power foundation upon which life-critical automation decisions are made.

Installation and Maintenance
Pre-installation preparation: Before installing the TRICONEX 4000098-510, verify that the Tricon chassis is de-energized and follow lockout/tagout (LOTO) procedures. Confirm that the AC input source matches site specifications (100–240 VAC) and that upstream breakers are rated appropriately. Inspect the module for physical damage and ensure the guide rails in slots 1 and/or 2 are clean and unobstructed. When used in redundant mode, install two TRICONEX 4000098-510 units to enable load sharing and failover capability.
Maintenance recommendations: Although the TRICONEX 4000098-510 is highly reliable, periodic checks are recommended. Use EDM software to monitor output voltage stability (should remain within 23.5–24.5 VDC) and current load (avoid sustained operation above 9 A). Inspect ventilation paths for dust accumulation, especially in dirty environments. If a module fault is indicated, replace it promptly—even in redundant setups—as single-module operation reduces safety margin. Always keep a spare TRICONEX 4000098-510 on hand for rapid recovery during unplanned outages.
