TRICONEX 3101S2 Power Supply Module Overview

The TRICONEX 3101S2 is a high-reliability redundant power supply module developed by Triconex (a core brand of Schneider Electric), specifically designed to provide stable and secure power for Triconex Safety Instrumented Systems (SIS). As a critical infrastructure component for safety-critical industrial control systems, it adopts a dual-redundant design to ensure uninterrupted power delivery—even in the event of a single power channel failure.

Compliant with SIL 3 safety standards and IEC 61508/IEC 61511 international norms, the module is engineered to withstand harsh industrial environments while delivering consistent output voltage for Triconex CPU modules, I/O modules, and other system components. Its robust design and advanced protection features make it an essential choice for high-risk industries where power stability directly impacts operational safety and continuity.

Core Features & Technical Advantages

• Dual-Redundant Design: Integrates two independent power supply channels with automatic failover (≤5ms switchover time), eliminating single points of failure and ensuring 24/7 power availability.
• Wide Input Voltage Range: Accepts 85-265VAC (50/60Hz) or 100-360VDC input, adapting to global industrial power grids and supporting both AC and DC power sources for flexible deployment.
• Stable DC Output: Delivers a regulated 24VDC output (adjustable ±5%) with high current capacity, capable of powering up to 16 Triconex I/O modules or a full rack of SIS components.

• Comprehensive Protection Mechanisms: Equipped with over-voltage, over-current, short-circuit, and over-temperature protection. Supports reverse polarity protection and surge suppression (IEC 61000-4-5) to safeguard connected equipment.

• Built-in Self-Diagnostics: Continuous monitoring of input voltage, output current, temperature, and channel status. Fault information is transmitted to the SIS controller via the backplane for real-time alerting and logging.
• High Efficiency & Low Ripple: Features a switching power supply design with ≥90% conversion efficiency, reducing energy consumption and heat generation. Output ripple ≤100mVpp ensures stable power for sensitive electronic components.
• Hot-Swappable Functionality: Supports online replacement of power supply channels without system shutdown, minimizing maintenance downtime and enhancing operational continuity.
• Seamless System Compatibility: Fully integrated with Triconex TMR architecture and all Triconex SIS product lines (including 3008, 3009, 3009X series modules), requiring no additional adapters for installation.

• Robust Environmental Adaptability: Industrial-grade housing with IP65 protection rating, operating temperature range of -40°C to 85°C, and resistance to vibration (IEC 60068-2-6) and electromagnetic interference (EMI).
