Description
The Yokogawa ANB10D-440 is an Enhanced-security Bus (ESB) node interface unit engineered for Yokogawa CENTUM VP and CENTUM CS 3000 Distributed Control Systems (DCS). In process control networks, this node unit acts as a remote housing rack that connects field I/O modules (such as analog and digital card sets) back to the main Field Control Unit (FCU) via high-speed ESB communication cables.

Technical Application & Integration Notes
The ANB10D-440 chassis accommodates dual power supply modules (such as PW484), dual bus interface master modules (such as SB401), and multiple slots for standard Yokogawa I/O cards (analog inputs/outputs, digital inputs/outputs). When configuring or expanding an existing node rack, verify that the node expansion software license (such as the NDEL option suffix) matches your system architecture limits.
During rack maintenance or module hot-swapping, ensure proper grounding protocols are followed and check that redundant 24 V DC power feeds are isolated safely to prevent backplane bus interruption on active control loops. For migrations or system expansions, note that the -440 variant has transitioned to newer hardware revisions like the ANB10D-445; verify firmware compatibility within CENTUM system builder software prior to installation.
Frequently Asked Questions
Q: What is the direct replacement model for the ANB10D-440?
A: Yokogawa phased out the ANB10D-440 in favor of the updated ANB10D-445 series node units. Ensure mechanical and communication compatibility if swapping units across system revisions.
Q: Does this unit support power supply redundancy?
A: Yes. The “-4” designator in the suffix code signifies support for dual-redundant 24 V DC power supply modules to maintain uninterrupted node uptime.
Q: Are I/O cards included with a standard ANB10D-440 chassis order?
A: Typically, base node units are supplied as empty or pre-populated racks depending on specific vendor surplus listings. Always confirm whether power modules (PW484), bus interface modules (SB401), or specific I/O cards are included in your procurement package.
