Selection Guide
Use the following criteria to confirm 6GK5612-0BA10-2AA3 is the correct module for your application:
- Step 1 — Identify base switch: Confirm your switch is SCALANCE X612-2. This module is not compatible with X208, X216, or XC-200 series.
-
Step 2 — Check approval requirements: If ATEX Zone 2 is required, confirm suffix
-2AA3. For IECEx, use-2AC2variant. - Step 3 — Verify hardware revision: Check the existing module’s HW revision label. Mixing HW revisions may affect redundancy behavior.
- Step 4 — Confirm firmware: Ensure switch firmware ≥ V4.0 for full feature support with this module revision.
- Step 5 — Quantity & lead time: Contact Konmask.com for stock availability and bulk pricing.
