Yokogawa ANB10D-421-S1 – ESB Bus Node Unit | CENTUM CS/VP DCS Platform
Engineering Background
The Yokogawa ANB10D-421-S1 is a dedicated ESB (Enhanced Signal Bus) Node Unit engineered for the CENTUM CS and CENTUM VP Distributed Control System (DCS) platforms — Yokogawa’s flagship process automation architecture deployed across refining, petrochemical, power generation, and pharmaceutical industries worldwide. The ESB bus architecture enables high-speed, deterministic communication between field control stations (FCS) and I/O subsystems, forming the backbone of real-time process control loops.
Product Positioning
The ANB10D-421-S1 serves as a critical node interface card that bridges the ESB communication bus to downstream I/O modules. It is designed for engineers maintaining, expanding, or replacing components within existing CENTUM CS/VP installations. Konmask.com supplies this unit as verified surplus stock, fully tested and ready for integration — eliminating the lead times associated with new OEM procurement.

- Traceable Provenance: Each unit sourced and inspected by Konmask.com’s technical team with documented handling records.
System Architecture & Signal Flow
Within the CENTUM CS/VP architecture, the ANB10D-421-S1 operates as a node on the ESB segment connecting the Field Control Station (FCS) processor to I/O modules. The ESB bus uses a token-passing protocol to guarantee deterministic scan cycles. The node unit manages bus arbitration, signal conditioning, and data buffering between the FCS backplane and downstream I/O sub-buses. This architecture supports redundant bus configurations for SIL-rated and high-availability applications.
Sourcing & Quality Verification
- All units are sourced from decommissioned or surplus industrial installations with documented removal records.
- Visual inspection: PCB, connectors, faceplate, and labeling checked against OEM reference standards.
- Functional bench test performed prior to listing (power-on, bus communication verification where applicable).
- Packaging: Anti-static ESD bag + foam-lined carton for international shipping compliance.
- Warranty: 90-day return-to-base warranty against functional defects.

Technical FAQ
Q: Is the ANB10D-421-S1 compatible with both CENTUM CS and CENTUM VP?
A: Yes. The ESB bus node architecture is shared across CENTUM CS and CENTUM VP generations. Confirm your specific FCS revision with our team for edge-case compatibility.
Q: Can this unit be used in a redundant ESB bus configuration?
A: Yes. CENTUM VP supports dual ESB bus redundancy. Two ANB10D-421-S1 units can be configured as primary/secondary nodes per Yokogawa’s redundancy guidelines.
Q: What is the typical lead time for OEM new units vs. Konmask surplus?
A: OEM new procurement typically requires 12–26 weeks. Konmask.com surplus stock ships within 3–7 business days after order confirmation.
Q: Do you provide a test report or certificate of conformance?
A: A functional test record is available upon request. Certificate of Conformance (CoC) can be issued for qualified B2B orders.
Q: What export documentation is available?
A: Commercial invoice, packing list, and country-of-origin declaration are standard. ECCN classification and end-user statement available for regulated destinations.
