3. Advantages and Characteristics

• Dual-Redundant Power Supply: Ensures uninterrupted operation in critical applications, minimizing downtime risks.
• Compact and Lightweight: 0.20 kg design for easy installation in space-constrained environments.
• Scalability: Supports multiple modules in a chassis (e.g., digital/analog I/O, communication modules).
• Stable Power Management: 220–240 V AC input with wide voltage tolerance (±10%) for global industrial use.
• Reliability: Robust construction for harsh conditions (temperature: -20°C to 70°C, corrosion resistance).

4. Application Areas and Cases

• Industries: Energy, chemical processing, manufacturing, and oil & gas.
• Scenarios: DCS communication hubs, remote terminal units (RTUs), and distributed control in hazardous locations.
• Case Study: A chemical plant deployed the ANR10D with dual-redundant power supply to manage 32 I/O modules in a corrosive environment. The unit’s redundant architecture and 2 kV isolation prevented power interruptions, ensuring 99.99% uptime over 3 years.

5. Competitor Comparison

Compared to similar bus node units, the ANR10D offers superior power redundancy (dual supply standard) and compatibility with Yokogawa’s legacy and modern systems. Its lightweight design (0.20 kg vs. 0.3–0.5 kg for competitors) and integrated explosion protection options reduce installation complexity and cost in hazardous zones.

6. Selection Recommendations

• Power Requirements: Verify voltage (220–240 V AC) and redundancy needs (dual supply for critical systems).
• Environment: Choose chassis and modules suitable for temperature (-20°C to 70°C) and corrosion (ISA G3) conditions.
• Scalability: Plan chassis configuration (e.g., ANR10D-420 with PW482 power module) based on I/O density.
• Compatibility: Ensure integration with Yokogawa DCS (Centum VP, ProSafe-RS) and third-party devices via ESB bus.

7. Precautions

• Installation: Follow chassis wiring diagrams; ensure proper grounding for EMI protection.
• Power Modules: Use approved modules (e.g., PW482) for stable 5.1 V/24 V DC output.
• Redundancy Testing: Regularly test dual-power supply failover to maintain system reliability.
• Explosion Zones: For hazardous environments, select certified explosion-proof variants (non-standard on ANR10D-0).
