ANB10D-425/CU2N Yokogawa ANB10D ESB Bus Node Unit

Yokogawa ANB10D-425/CU2N Dual-Redundant ESB Bus Node Unit

01 | Hardware Identity and System Role

The Yokogawa ANB10D-425/CU2N is an ESB bus node unit for Yokogawa distributed control system installations. The ANB10D supports a dual-redundant ESB bus architecture. Its rack-mounted assembly provides an interface for connecting compatible I/O modules to the control system. This ordering configuration includes a dual-redundant power supply, a 220–240 V AC supply option, and an ESB bus connector unit. The specified assembly weighs approximately 10 kg, including eight I/O modules.

02 | Configuration Anatomy: Decode ANB10D-425/CU2N

**Selected configuration:** ANB10D-425/CU2N - Dual-redundant ESB bus node. - Dual-redundant power supply. - 220–240 V AC input. - Basic type without explosion protection. - ESB bus connector unit included in the model designation.

03 | Technical Specifications

The alternative supply ratings describe the ANB10D family. They do not change the selected 220–240 V AC configuration.

04 | Power and Bus Architecture

The ANB10D serves as a node within a dual-redundant ESB bus arrangement. Engineers should confirm the compatible control unit, bus coupler, and system topology. Its dual-redundant power supply provides the specified redundant power configuration. The actual redundancy performance depends on the complete power distribution design. Before integrating the node, verify:

• Control system and ESB bus compatibility.
• Approved bus coupler and connector arrangement.
• Power supply wiring and redundancy design.
• Installed I/O module types and quantity.
• System configuration and node addressing requirements.

The supplied information does not specify maximum node counts, bus cable lengths, or communication timing. Consult the applicable Yokogawa system documentation.

05 | Rack Installation and Cabinet Planning

The ANB10D-425/CU2N uses a 19-inch rack mounting arrangement. The supplied mounting specification identifies four M5 screws and insulation bushes. **Installation checklist**

1. Confirm the rack accepts the unit's mounting dimensions.
2. Check the available rack space and access for bus connections.
3. Verify the 220–240 V AC supply and 50/60 Hz frequency.
4. Inspect the insulation bushes and mounting hardware.
5. Secure the assembly using the specified mounting arrangement.
6. Connect the approved ESB bus interface.
7. Verify I/O module positions against the cabinet drawings.
8. Inspect wiring and grounding before commissioning.

The supplied product data does not provide exact rack clearance, terminal torque, or conductor size. Use the manufacturer's installation instructions for these details.

06 | Compatible Equipment and Industrial Applications

The ANB10D is designed for compatible Yokogawa ESB-based distributed control system installations.

• Distributed control systems: Connect supported I/O modules through the ESB bus architecture.
• Process automation: Integrate field I/O in engineered chemical, petrochemical, and manufacturing control systems.
• Power and utility plants: Support distributed process monitoring and control cabinets.
• Industrial plant expansion: Add a node where the existing control system supports the required hardware and configuration.
• Cabinet replacement projects: Replace a matching node after verifying bus, power, and module compatibility.

Confirm the exact controller family and I/O module compatibility before purchase. The model description alone does not establish compatibility with every Yokogawa system.

07 | Diagnostics and Commissioning Checks

The supplied specifications do not identify onboard diagnostic indicators, detailed fault codes, or specific diagnostic software functions. Use the relevant Yokogawa system tools and manuals for module-level diagnostics. During commissioning, check the following areas:

• Power supply: Confirm the AC input and investigate power alarms through approved system diagnostics.
• Redundant power: Verify both supply paths according to the system's commissioning procedure.
• ESB communication: Check connector seating, bus wiring, and controller recognition.
• I/O configuration: Compare installed module positions with the system configuration.
• Node identification: Confirm addressing and configuration match the engineering records.
• Field signal validation: Test representative I/O points through their connected modules.

**Field example:** If the controller does not recognize a newly installed node, check the ESB connection and configuration first. Then verify the power supply and installed module arrangement. These checks help isolate installation issues before replacing hardware.

08 | Compatibility and Procurement Review

Confirm these details before ordering a replacement or expansion unit:

• Complete model code: ANB10D-425/CU2N.
• Existing ESB bus architecture and compatible control unit.
• Required connector unit and bus cable arrangement.
• Installed I/O module types and quantity.
• 220–240 V AC supply availability.
• Rack mounting provisions and cabinet space.
• Environmental requirements and explosion protection classification.

The selected basic configuration does not include explosion protection. Confirm site requirements before installation in any classified area.

09 | Global PLC Spare HUB's Insight

The ANB10D should be selected as a complete node assembly rather than as an isolated rack component. Its suitability depends on the ESB architecture, power arrangement, and installed I/O modules. For example, during a control cabinet expansion, an engineer may need to add another node while retaining the existing bus structure. The engineer should verify the controller's supported node capacity, cable arrangement, and configuration requirements. The stated 10 kg weight includes eight I/O modules. Confirm the actual supplied assembly and module complement when planning handling, rack loading, or a replacement project.
