ANB10D-415/CU2N/NDEL YOKOGAWA ESB Bus Node Unit

ANB10D-415/CU2N/NDEL is a Yokogawa ESB-bus node unit for distributed I/O that provides the interface between field I/O modules and a Field Control Unit (FCU).

The model delivers dual-redundant capabilities (power / bus), accepts standard ESB connector units (/CU2N), and includes the NDEL

option (software license for node expansion). It’s a 19-inch rack module used in CENTUM-class

DCS installations for robust, high-availability I/O expansion.

Frequently Asked Questions

Q — What does this module actually do in the DCS?
A — It is the remote I/O node: it accepts field I/O modules (analog/digital), supplies their power, and communicates those I/O points back to the FCU over the ESB bus.

You install one or more ANB10D units in I/O racks to scale field I/O.

Q — Why would I choose the ANB10D-415/CU2N/NDEL (vs a basic node)?
A — Choose this variant when you need dual-redundant power / bus for higher availability, the CU2N connector unit for ESB wiring, and the

NDEL license to allow node-expansion topologies required by your system design. These features are

common in process plants needing high uptime.

Q — Is this module suitable for hazardous/explosion-proof installations?
A — The basic ANB10D is a standard rack module. Explosion-proof or ATEX/IECEx options require specific suffixes/options;

the basic “/NDEL/CU2N” package is not itself an explosion-proof certified field node. Specify explosion-rated options

(/ATDOC or similar per Yokogawa guides) if you need hazardous-area compliance.
