Yokogawa ANB10D-425 Node Interface Unit

Configured for network interfacing in V-net/IP control architectures, the Yokogawa ANB10D-425 Node Interface Unit provides direct physical/electrical execution of high-speed data exchange between control stations and distributed network segments.

Hardware Specifications

Process Control and DCS Instrumentation Characteristics

• 4-20 mA HART loop protocol: The unit facilitates transparent routing of HART diagnostic data from field devices, enabling real-time monitoring and parameterization within the DCS master station.
• FOUNDATION Fieldbus / Profibus PA connectivity: The interface supports standardized digital fieldbus protocols, ensuring interoperability across complex distributed control system topologies.
• Channel-to-channel isolation: Internal galvanic isolation barriers prevent common-mode electrical noise and ground loop currents from migrating between the network interface and connected control station components.
• Cold junction compensation (CJC): The unit manages active compensation for thermocouple-based instrumentation to ensure high-accuracy temperature signal processing in sensitive process loops.

Frequently Asked Questions

Q: Does the ANB10D-425 support redundant network configurations?

A: Yes. The unit supports dual-redundant network configurations, providing high availability for system communication links and ensuring continued operation during link failure.

Q: What are the physical mounting options for this unit?

A: The module is engineered for installation in confined spaces and supports both DIN-rail and wall-mounting configurations to provide maximum deployment flexibility in control cabinets.

Field Installation Guidelines

• Mounting: Secure the unit to a standard DIN-rail or wall surface using the integrated mounting provisions. Ensure the site is free from excessive vibration and provides adequate air circulation for passive cooling.
• Grounding: Bond the module chassis to the cabinet’s instrument earth bus using a low-impedance conductor. Robust grounding is mandatory to maintain signal integrity and maximize the module's electromagnetic immunity.
• Wiring: Connect the 24 V DC power supply to the designated input terminals, ensuring voltage stability within the specified range. V-net/IP communication cabling should be shielded and segregated from high-power AC lines by a minimum of 150 mm to avoid inductive interference.
