Product Introduction
Node units are the backbone of FCS I/O expansion, but they are often confused with remote nodes or FCU racks. The /CU2T is a YOKOGAWA CENTUM CS 3000 / CENTUM VP ESB bus node unit. The series indicates a dual-redundant node unit, 415 identifies the dual-redundant ESB bus, dual-redundant power supply, basic type with no explosion protection configuration, and is a suffix code for a specific configuration variant.
For maintenance and procurement teams, this unit is typically sourced as an OEM replacement for failed or aging node units in CENTUM CS 3000 / CENTUM VP FCS environments. It mounts in a standard 19-inch rack and houses power supply modules (PW481/PW482/PW484) and ESB bus slave interface modules (SB401), providing the interface between the FCU and field I/O modules. Because the CU2T suffix may differ from CU2N or other variants in configuration details, the physical label should be confirmed before substitution.

Key Selling Points & Differentiators
- Dual-redundant ESB bus: Supports redundant communication with the FCU for high availability.
- Dual-redundant power supply: Reduces single-point power failure risk at the node level.
- 19-inch rack mount: Standard industrial mounting for easy integration into FCS cabinets.
- OEM YOKOGAWA node unit: Suitable for CENTUM CS 3000 / CENTUM VP maintenance, replacement, or spare stocking.
- Non-explosion-proof basic type: The 415 configuration is suitable for general industrial control room or cabinet environments.
- Not recommended for: Remote node applications (use ANR10*), single-redundant bus requirements (use ANB10S), explosion-proof areas, or direct FCU replacement. Always confirm the CU2T suffix and power module configuration before ordering.
Quality Transparency SOP
Node units should be verified for both mechanical integrity and bus/power module compatibility.
- Incoming visual QA: Inspect factory sealing, label integrity, rack mounting points, and module slot condition.
- Label verification: Confirm full model and suffix match the required configuration.
- Module slot inspection: Check power module and SB401 module slots for bent pins, oxidation, or mechanical damage.
- Power module check: Confirm installed power modules (PW481/PW482/PW484) match the existing node configuration.
- ESB interface check: Verify SB401 module presence and connector integrity for dual-redundant ESB bus connection.
- Final packing: Record serial/lot information, apply protective packaging, and seal with a condition label.
Technical Risk Avoidance
Confirm the CU2T suffix. variants such as CU2N and may differ in configuration. Always match the full model against the existing unit label before substitution.
Do not confuse with remote nodes. ANB10D is a local ESB bus node unit. Remote node applications require ANR10* series units connected via ER bus.
Verify power module compatibility. The node unit houses PW481/PW482/PW484 power modules. Confirm the voltage rating and redundancy configuration match the existing system.
Check ESB bus addressing. Node units require correct ESB bus address settings. Installing a unit without confirming the address can cause communication faults with the FCU.
Confirm FCU coupler type. The FCU must have an EC401 or EC402 ESB bus coupler module to connect to ANB10D node units.
Respect the per-FCU node limit. A single FCU supports up to 10 nodes (local + remote), with remote nodes limited to 8.
Buyer’s FAQ
Is this unit genuine YOKOGAWA?
Yes. The is an OEM YOKOGAWA CENTUM CS 3000 / CENTUM VP ESB bus node unit. We supply it as new original/new surplus unless otherwise stated.
oes / do?
It is a dual-redundant ESB bus node unit that houses power supply modules and SB401 ESB slave interface modules, providing the interface between the FCU and field I/O modules in a 19-inch rack.
Can I replace ANB10D-415/CU2N with this unit?
Not automatically. CU2N and CU2T may differ in configuration details. Always confirm the full model and physical label before substitution.
Can I use it as a remote node?
No. ANB10D is a local ESB bus node unit. Remote node applications require ANR10* series units.
What power modules does it support?
PW481, PW482, or PW484 power supply modules, depending on the voltage and redundancy configuration.
What is the warranty and lead time?
Each unit carries a standard 12-month functional warranty from shipment, excluding damage from incorrect installation, address mismatch, or power module incompatibility. In-stock units typically ship within 1–3 business days after payment confirmation.
