Dual-Redundant Architecture: Yokogawa ANR10D-420 supports dual-redundant power supplies (220–240 VAC or 24 VDC) and redundant ER/ESB bus communication, ensuring uninterrupted operation in critical industrial environments like oil refineries and power plants.

Modular and Scalable Design: Features a hot-swappable, modular architecture that supports up to 14 nodes (local and remote) for flexible I/O expansion. Compatible with analog/digital I/O, temperature sensors, and pressure transmitters .

Industrial-Grade Durability: Yokogawa ANR10D-420 is designed for 19-inch rack mounting and operates in harsh conditions, with an operating temperature range of 0°C to +50°C and humidity tolerance up to 90% RH (non-condensing). The IP66-rated enclosure ensures dust/water resistance.

Self-Diagnostic and Maintenance Support: Includes built-in diagnostics to monitor system health and trigger alerts for anomalies. Supports predictive maintenance through historical data logging and fault detection.
Compatibility with Safety Systems: Yokogawa ANR10D-420 supports explosion-proof configurations (e.g., suffix codes /ATDOC for hazardous area compliance) and integrates with safety-critical applications like emergency shutdown systems in chemical plants or offshore platforms.

Redundant Process Control in Oil and Gas Refineries: Yokogawa ANR10D-420 provides dual-redundant ESB bus connectivity for Yokogawa’s CENTUM VP systems, ensuring uninterrupted communication between field devices (e.g., pressure sensors, flow meters) and control units in critical processes like crude distillation or pipeline monitoring. Its redundancy minimizes downtime during power or communication failures, crucial for safety in volatile environments .

Power Plant Safety and Grid Management: In thermal or nuclear power plants, this node unit interfaces with Field Control Units to monitor turbine parameters, steam pressure, and coolant flow. It supports high-speed data transfer via ESB bus, enabling real-time adjustments to optimize fuel efficiency and comply with grid stability requirements .

Pharmaceutical Cleanroom Automation: Integrates with Yokogawa’s DCS to regulate environmental parameters (e.g., temperature, humidity, air pressure) in sterile manufacturing facilities. The 19-inch rack-mountable design allows scalable I/O configurations for precise control of drug formulation and packaging lines.

Water Treatment Plant Redundancy: Yokogawa ANR10D-420 is deployed in municipal or industrial water facilities, the ANR10D-420 connects pumps, valves, and filtration systems via ESB protocols. Dual-redundant power supplies (100–240 V AC or 24 V DC) ensure continuous operation during voltage fluctuations, critical for maintaining water quality and regulatory compliance.
