Selection Guide
Use the table below to select the correct Profibus DP interface card for your DeltaV system:
| Model | Revision | DeltaV Version | Max Nodes | Recommended Use |
|---|---|---|---|---|
| KJ3243X1-BA1 | Rev A | v7.3 – v10.x | 125 | Legacy systems |
| KJ3243X1-BB2 | Rev B | v8.x – v14.x | 125 | Current standard (recommended) |
| KJ3243X1-BC1 | Rev C | v11.x – v14.x+ | 125 | New installations with enhanced diagnostics |
If your DeltaV system is v11 or above and you require enhanced diagnostic features, consider upgrading to KJ3243X1-BC1. For legacy v7.3–v10.x systems, KJ3243X1-BA1 or BB2 are both suitable.
