Not compatible with YOKOGAWA ProSafe-RS or STARDOM platforms without additional interface modules.
Selection Guide
Use the following criteria to confirm the DX11*A is the correct card for your application:
- Step 1 — Identify your system: Confirm your CENTUM system model and revision (CS / CS3000 / VP).
- Step 2 — Verify the suffix: The asterisk (*) in DX11*A represents a sub-variant character. Check your existing card label or system BOM for the exact suffix.
- Step 3 — Check slot position: Confirm the card is installed in a duplex-capable FCU (Field Control Unit) slot.
- Step 4 — Confirm firmware: Ensure your FCU firmware version supports the DX11*A revision you are sourcing.
- Step 5 — Evaluate upgrade path: If your system is CENTUM VP R5 or later, consider the CP461-50 as a long-term upgrade option.

Replacement & Compatibility FAQ
Q: Can I use a DX11-B to replace a DX11-A?
A: In most CENTUM CS 3000 configurations, yes — but firmware compatibility must be verified. Contact us for a system-specific assessment.
Q: Is the DX11*A still in production?
A: YOKOGAWA has transitioned newer systems to the CP4xx series. DX11*A units are available as new-old-stock (NOS) or refurbished. We maintain stock for MRO and emergency replacement needs.
Q: What is the lead time for DX11*A?
A: In-stock units ship within 3–5 business days. Out-of-stock items typically have a 4–8 week lead time depending on sourcing channel.
Q: Do you provide a warranty?
A: Yes. All units carry a minimum 90-day functional warranty. Extended warranty options are available — contact us for details.
Q: Can you supply the full FCU assembly, not just the control card?
A: Yes. We can source complete FCU assemblies and related CENTUM system components. Please provide your full BOM for a comprehensive quote.
