Key Features and Functionality:

1. Purpose:
   • Acts as a communication node connecting N-IO (Network Input/Output) and FIO (Field Input/Output) modules to Yokogawa’s control systems (e.g., CENTUM VP DCS).
   • Facilitates data exchange between field devices (sensors, actuators) and the control network.
2. ESB Bus:
   • Likely refers to Yokogawa’s proprietary “Extended Serial Backbone” or similar bus system used for high-speed communication between I/O nodes and controllers.
3. Part Number Breakdown:
   • ANB10D: Base model designation for the bus node unit.
   • 415: May indicate a 415V AC power supply rating or a specific variant.
   • CU2T:
     • CU: Copper-based communication interface (e.g., Ethernet, RS-485).
     • 2T: Two communication ports or terminals (possibly for redundancy or daisy-chaining).
4. Compatibility:
   • Integrates with Yokogawa’s N-IO/FIO modules, which handle analog/digital I/O signals (e.g., 4-20mA, discrete signals).
   • Part of the FAST/TOOLS or CENTUM VP system architecture for process automation.
5. Typical Applications:
   • Industrial environments (oil/gas, chemical plants) requiring robust communication between field devices and control systems.
   • Supports protocol conversion, signal isolation, and network redundancy.

Technical Considerations:

• Communication Protocols: Likely supports Yokogawa’s Vnet/IP or legacy protocols (e.g., Foundation Fieldbus, Profibus) depending on configuration.
• Redundancy: May feature dual ports (CU2T) for fault-tolerant network designs.
• Certifications: Likely rated for harsh environments (e.g., hazardous areas with ATEX/IECEx certifications).
