Selection Guide
Use the following criteria to determine whether the FEM100 P0973CA is the right module for your application:
- Existing I/A Series DCS? → FEM100 P0973CA is the preferred OEM choice.
- Need FOUNDATION Fieldbus H1 connectivity? → Confirm segment count requirements (1–4 H1 segments per module).
- Replacing a failed module? → Match part number and hardware revision; check firmware compatibility in your I/A Series release notes.
- Upgrading or expanding? → Consider FBM230/231 for enhanced diagnostics and future-proofing.
- Cross-platform migration? → Consult Konmask engineering support for a full migration assessment.
- Budget-constrained? → Refurbished/tested FEM100 units are available; request certification documentation.
