Product Introduction
A failed remote node can disconnect an entire I/O island from the DCS before any field device faults. The YOKOGAWA ANB10D-415/CU2N is a CENTUM VP ESB bus node unit used to connect remote analog and contact I/O modules to the Field Control Unit through a dual-redundant ESB bus.
The “ANB10D” family identifies a dual-redundant ESB bus node unit in 19-inch rack-mount form. The suffix “-415” denotes the basic type with no explosion protection, and “/CU2N” is an option code that must be confirmed against the nameplate. The node unit itself does not carry I/O channels directly; it houses a power supply module such as PW481/PW482/PW484 and an ESB bus interface slave module such as SB401, which then supplies power and communication to the installed I/O modules.
This product is typically deployed in remote I/O cabinets, utility islands, skid packages, and auxiliary plant areas where I/O must be located away from the main FCS rack. Because ANB10D nodes can be ordered with different suffix and option codes — such as /CU2N, /CU2T, or /NDEL — the exact configuration should be verified before replacement.

Key Selling Points & Differentiators
- Dual-redundant ESB bus node for CENTUM VP remote I/O expansion.
- 19-inch rack-mount form suitable for remote I/O cabinets and skids.
- Basic non-explosion-proof configuration for general industrial areas.
- Direct replacement when node address, suffix, and option codes match.
- Factory-sealed surplus inventory with visual QA and 12-month warranty.
- Not a standalone I/O card; it requires compatible power and ESB interface modules.
Quality Transparency SOP
- Visual inspection: Verify label “ANB10D-415/CU2N,” chassis condition, and module slots.
- Seal verification: Confirm original packaging and factory labeling when supplied sealed.
- Suffix cross-check: Match -415 and /CU2N with the replaced node unit.
- Module check: Confirm installed PW48x power supply and SB401 ESB slave module.
- Address check: Record and match node address settings before installation.
- Communication test: Verify ESB bus link, redundancy status, and I/O module recognition after power-up.
Technical Risk Avoidance
❗ Confirm the full order code. ANB10D-415/CU2N is not automatically interchangeable with ANB10D-415/CU2T, ANB10D-425/CU2N, or ANB10D-415/NDEL variants.
❗ This is a node unit, not an I/O module. It must be equipped with the correct power supply and SB401 ESB bus interface slave module to operate.
❗ Verify node address and ESB bus configuration. Mismatched addressing can cause communication loss across the remote I/O segment.
❗ Check power supply voltage. ANB10D nodes support different power options; the installed PW module must match the cabinet supply.
❗ Do not substitute ANB10D for ANR10D/ANR11D without confirmation. ANR-series nodes may have different bus, environmental, or certification characteristics.
Buyer’s FAQ
Is the YOKOGAWA ANB10D-415/CU2N a genuine OEM part?
Yes. It is supplied as an original Yokogawa CENTUM VP ESB bus node unit, typically as new surplus or factory sealed.
Whatthe / do?
It serves as a dual-redundant ESB bus node unit that connects remote I/O modules to the CENTUM VP Field Control Unit.
Can it replace other ANB10D models?
Only if the suffix, option code, node address, and installed modules match. ANB10D variants are not universally interchangeable.
Does it include I/O modules?
No. The node unit provides power and ESB bus communication; I/O modules are installed separately in the node.
What warranty do you offer?
A 12-month warranty against manufacturing defects and DOA issues. Damage from incorrect node addressing, wrong power supply, missing SB401 module, or incompatible option codes is not covered.
