Selection Guide
Use the following criteria to confirm the VI451-10 S3 is the right module for your application:
- Step 1 – Identify your DCS platform: Confirm CENTUM VP or CS 3000 system version.
- Step 2 – Check communication requirement: RS-232C, RS-422, or RS-485 serial interface needed?
- Step 3 – Verify nest slot availability: Confirm open I/O slot in the target ANB nest.
- Step 4 – Check revision compatibility: S3 suffix indicates hardware revision; match with your system’s supported revision list.
- Step 5 – Confirm quantity: Each VI451-10 S3 supports one serial channel; multiple modules required for multi-device topologies.

Replacement & Compatibility FAQ
Q: Can the VI451-10 S3 replace the VI451-10 S2 directly?
A: In most cases yes, as the S3 is a later hardware revision. However, verify your CENTUM VP firmware version supports the S3 revision before installation.
Q: Is the VI451-10 S3 compatible with CENTUM VP R6?
A: Yes, the VI451-10 S3 is supported on CENTUM VP R4 through R6. Consult Yokogawa’s hardware compatibility matrix for your specific release.
Q: Can I use a third-party serial gateway instead?
A: Technically possible with protocol converters, but not recommended for safety-critical loops. Engineering validation and re-commissioning are required.
Q: Do you provide a warranty?
A: Yes. New units carry manufacturer warranty. Refurbished units carry a 90-day Konmask functional warranty. Contact us for details.
Q: Can you help me identify the right replacement if my part number is different?
A: Absolutely. Email us your full part number, system model, and revision, and our engineers will provide a cross-reference recommendation within 24 hours.
