YOKOGAWA CP99A*A S9581AS-0 Central Processing Unit Card – CENTUM CS 3000 DCS
Imagine a refinery control room where the distributed control system suddenly loses its central processing unit. Alarms cascade across every loop, operators lose visibility into critical process variables, and production grinds to a halt — every minute of downtime translating directly into lost revenue and potential safety incidents. The CP99A*A S9581AS-0 is the nerve center of the CENTUM CS 3000 field control station: without it, the entire automation architecture is blind. Sourcing a verified replacement quickly is not a convenience — it is an operational imperative.
The CP99A*A S9581AS-0 occupies the top tier of YOKOGAWA’s CENTUM CS 3000 processor family. As the primary CPU card for the Field Control Station (FCS), it executes all real-time control calculations, manages I/O bus communication, and maintains redundancy synchronization in dual-redundant configurations. CENTUM CS 3000 remains one of the most widely deployed DCS platforms across oil & gas, petrochemical, power generation, and specialty chemical industries globally, with an installed base spanning more than 30 countries. This processor card is a mission-critical spare that plant engineers and procurement teams actively seek to maintain system uptime.

Frequently Asked Questions
Q: Is the CP99A*A S9581AS-0 compatible with CENTUM VP?
A: No. The CP99A*A is designed specifically for the CENTUM CS 3000 platform. CENTUM VP uses a different processor architecture (e.g., CP461). Please confirm your DCS generation before ordering.
Q: Can this card be used in a non-redundant FCS configuration?
A: Yes. The CP99A*A S9581AS-0 supports both simplex and dual-redundant FCS configurations. Redundancy is determined by the FCS chassis and pairing setup, not the card itself.
Q: Do you provide a test report with the unit?
A: Yes. All refurbished units ship with a functional test report. New surplus units include original factory documentation where available.
Q: What is the typical lead time?
A: In-stock units ship within 2 business days. If sourcing is required, lead time is typically 7–14 business days. Contact us for real-time availability.
Q: Can you assist with installation or commissioning?
A: We provide technical documentation and remote guidance. On-site commissioning services can be arranged through our partner network upon request.
