Yokogawa ANB10D-420/CU2N ESB Bus Node Unit Overview
The Yokogawa ANB10D-420/CU2N is an industrial-grade ESB (Enhanced Serial Bus) node unit engineered to establish robust communication pathways between field instrumentation and Field Control Units (FCU) within CENTUM VP distributed control systems. This dual-redundant configuration ensures uninterrupted I/O signal transmission while simultaneously delivering regulated power to connected I/O modules, making it essential infrastructure for mission-critical process automation environments.
Technical Specifications
- Model Designation: ANB10D-420/CU2N
- Bus Architecture: Dual-redundant ESB bus interface
- Power Supply: 24 VDC (dual-redundant configuration)
- Power Consumption: 5.5A maximum at 24VDC
- I/O Module Capacity: Supports up to 8 I/O modules per node
- Maximum Node Units: 8 units connectable (model-dependent: A2FV50/A2FV70/AFV30/AFV40)
- Mounting: 19-inch rack mounting (M5 x 4 screws)
- Weight: Approximately 10 kg (including 8 I/O modules)
- Included Accessories: Insulation bash, 2x Connector Units for ESB Bus (S9562FA)
- Operating Temperature: Standard industrial range (extended options available)
- Compatibility: CENTUM VP R5 and earlier; R6.01+ with /NDEL option
Application Scenarios
The ANB10D-420/CU2N excels in distributed control architectures where field-level intelligence must communicate reliably with supervisory control layers. Typical deployment scenarios include:
- Refinery Process Control: Interfacing temperature, pressure, and flow transmitters across distillation columns, heat exchangers, and reactor vessels where 24VDC power infrastructure is standardized
- Chemical Batch Manufacturing: Coordinating analog control valves, level sensors, and discrete interlocks for recipe-driven production sequences requiring deterministic I/O response times
- Power Generation Auxiliary Systems: Managing boiler feedwater controls, cooling tower instrumentation, and emissions monitoring equipment in balance-of-plant applications
- Pharmaceutical Clean Utilities: Monitoring purified water loops, HVAC differential pressure, and clean steam generation with validated control system architectures
System Integration Architecture
The dual-redundant ESB bus design provides automatic failover capability—if the primary communication path experiences a fault, the secondary bus instantaneously assumes control without process interruption. This architecture is particularly valuable in continuous process industries where unplanned downtime translates directly to production losses and quality deviations.
Integration with CENTUM VP Field Control Units requires EC401 or EC402 ESB Bus Coupler Modules, which translate high-speed controller instructions into field-level I/O operations. The included CU2N connector units (Part No. S9562FA) provide standardized cabling interfaces, simplifying installation and reducing commissioning time. The 24VDC power option aligns with intrinsically safe and low-voltage control panel designs common in hazardous area classifications.
Operational Benefits
Deploying the ANB10D-420/CU2N delivers measurable advantages: reduced single-point-of-failure risk through redundant bus topology, simplified power distribution via integrated I/O module supply, and scalable architecture supporting up to 8 node units per control station. The 19-inch rack mounting standard ensures compatibility with existing control room infrastructure, while the 10 kg weight (fully populated) facilitates ergonomic installation and maintenance access.
Advanced diagnostics continuously monitor bus health, power supply status, and I/O module communication integrity. Any detected anomaly triggers immediate alarm notification to the operator interface, enabling proactive maintenance before faults impact process operations. Hot-swappable I/O modules minimize mean-time-to-repair during component replacement activities.
