Compatible Replacement & Equivalent Models
When the ADV551-P50 S2 is unavailable or end-of-life, the following models may serve as functional replacements or equivalents depending on your system configuration. Always validate compatibility with your system integrator before substitution.
| Model | Manufacturer | Type | Compatibility Notes |
|---|---|---|---|
| ADV551-P50 S1 | YOKOGAWA | Direct predecessor | Earlier hardware revision; verify firmware compatibility |
| ADV551-P50 S3 | YOKOGAWA | Newer revision | May be drop-in replacement; confirm with YOKOGAWA |
| ADV151-P50 | YOKOGAWA | Analog Output (reference) | Different signal type; not a direct replacement |
| F3YD32-0N | YOKOGAWA (FA-M3) | DO Module (FA-M3 platform) | Different platform; not interchangeable |
| 1756-OB16I | Allen-Bradley (Rockwell) | DO Module (ControlLogix) | Cross-brand; requires gateway/adapter for CENTUM VP |
| 6ES7 322-1BL00-0AA0 | Siemens | DO Module (S7-300) | Cross-brand; not directly compatible with CENTUM VP |
⚠ Important: Cross-brand replacements require engineering validation. Konmask.com recommends using genuine YOKOGAWA modules for safety-critical applications.

System Compatibility
| DCS Platform | Compatible | Notes |
|---|---|---|
| YOKOGAWA CENTUM VP | ✅ Yes | Primary target platform |
| YOKOGAWA CENTUM CS 3000 | ✅ Yes (verify revision) | Confirm hardware suffix compatibility |
| YOKOGAWA CENTUM CS 1000 | ⚠ Partial | Consult YOKOGAWA engineering |
| YOKOGAWA ProSafe-RS | ❌ No | Safety system uses dedicated SIL-rated modules |
| Third-party DCS (ABB, Emerson, Siemens) | ❌ No | Not compatible without significant engineering |
Selection Guide
Use the following decision framework to determine whether the ADV551-P50 S2 is the right module for your application:
- Confirm your DCS platform: Is it YOKOGAWA CENTUM VP or CS 3000? If yes, proceed.
- Verify I/O nest slot type: Ensure the target slot accepts ADV5xx series modules.
- Check output signal requirements: Do you need 24 VDC transistor digital output? If yes, ADV551 is appropriate.
- Confirm channel count: Does your application require 16 DO channels per module? If more channels are needed, consider multiple modules or a higher-density variant.
- Review suffix (S2): The S2 suffix denotes a specific hardware revision. Confirm your system’s firmware version supports S2 modules via YOKOGAWA’s compatibility matrix.
- Safety classification: For SIL-rated loops, do NOT use ADV551 — use YOKOGAWA ProSafe-RS dedicated safety modules instead.
- Spare parts strategy: For long-term plant maintenance, consider stocking 1–2 spare ADV551-P50 S2 modules per critical control loop.

Replacement & Compatibility FAQ
Q: Can I use ADV551-P50 S1 instead of S2?
A: Possibly. The S1 is an earlier hardware revision. Compatibility depends on your CENTUM VP firmware version. Consult YOKOGAWA’s hardware compatibility matrix or contact our technical team.
Q: Is the ADV551-P50 S2 compatible with CENTUM CS 3000?
A: Yes, in most configurations. Verify the I/O nest type and firmware version to ensure full compatibility.
Q: Can I replace ADV551-P50 S2 with a Siemens or Allen-Bradley DO module?
A: Not directly. Cross-brand substitution requires protocol gateways and significant re-engineering. We strongly recommend using genuine YOKOGAWA modules for CENTUM VP systems.
Q: What is the lead time for ADV551-P50 S2?
A: In-stock units ship within 3–5 business days. For out-of-stock situations, lead time is typically 4–8 weeks. Contact us for current availability.
Q: Do you provide a certificate of conformance (CoC)?
A: Yes. CoC and inspection reports are available upon request for all orders.
Q: Can I return a module if it’s incompatible with my system?
A: Yes, within 30 days of receipt, provided the module is unused and in original packaging. Contact support@konmask.com to initiate a return.
