System Compatibility
| Drive Series | Compatible | Notes |
|---|---|---|
| ABB DCS550-S | ✅ Yes | Primary target platform |
| ABB DCS550-A | ✅ Yes | Verify hardware revision |
| ABB DCS400 | ⚠️ Partial | Check board revision compatibility |
| ABB DCS500 | ❌ No | Different board architecture |
| Third-party DC Drives | ❌ No | ABB-specific design |
Selection Guide
Use the following decision framework to select the correct board for your application:
- Step 1 – Identify your drive model: Confirm the exact DCS550 model number from the drive nameplate (e.g., DCS550-S01-0060-05-00P).
- Step 2 – Check hardware revision: The SDCS-PIN-3B is compatible with hardware revision C and above. Earlier revisions may require SDCS-PIN-3A.
- Step 3 – Confirm firmware version: Drives running firmware below V5.x may require a firmware update before installing SDCS-PIN-3B.
- Step 4 – Evaluate refurbished vs. new: For critical production lines, new original parts are recommended. Refurbished boards are suitable for backup inventory or non-critical applications.
- Step 5 – Contact Konmask: Our technical team can cross-reference your drive serial number against ABB’s parts database to confirm exact compatibility.

Replacement & Compatibility FAQ
Q: Can SDCS-PIN-3A replace SDCS-PIN-3B?
A: In most cases yes, but SDCS-PIN-3B includes circuit improvements over the 3A revision. We recommend using 3B as the preferred replacement for 3A, not the reverse.
Q: Is the SDCS-PIN-3B still in production by ABB?
A: ABB periodically revises its spare parts catalog. Contact us for current availability and lead time from ABB’s supply chain.
Q: Do you offer exchange / core return programs?
A: Yes. We accept faulty SDCS-PIN-3B boards as core returns for credit toward a replacement unit. Contact us for details.
Q: What is the warranty on your boards?
A: All boards carry a 90-day replacement warranty. Extended warranty options are available for volume orders.
Q: Can I use a third-party equivalent board?
A: Third-party equivalents exist but are not recommended for critical production environments due to potential compatibility and reliability risks. Always consult your drive documentation and our technical team before substituting.
