Compatible Replacement & Equivalent Models
When the original FBM203 / P0914SV is unavailable or end-of-life, the following options are commonly evaluated:
- Foxboro FBM203 P0914SV — Original OEM unit (new, refurbished, or surplus)
- Foxboro FBM204 / P0914TT — Thermocouple input variant; verify input type compatibility before substitution
- Foxboro FBM201 / P0914QQ — Analog input module; suitable for 4–20 mA RTD transmitter outputs
- Third-party I/A Series-compatible RTD modules — Confirm firmware revision and backplane slot compatibility
⚠ Always verify part number suffix, firmware version, and backplane compatibility before ordering a replacement. Contact support@konmask.com for cross-reference assistance.

Selection Guide
Use the table below to select the correct FBM module for your RTD input requirements:
- RTD direct wiring (Pt100/Pt200/Pt1000), 8 channels → FBM203 / P0914SV ✔
- Thermocouple inputs (J, K, T, E, R, S, B) → FBM204 / P0914TT
- 4–20 mA analog inputs (RTD transmitter) → FBM201 / P0914QQ
- High-density RTD (16 ch) → Consult Foxboro product catalog for FBM2xx series
- HART-enabled RTD input → FBM214 or FBM216 series

Replacement & Compatibility FAQ
Q: Is FBM203 P0914SV still in production?
A: The FBM203 has reached end-of-active-production. Konmask.com supplies tested surplus and refurbished units with full warranty.
Q: Can I use FBM204 instead of FBM203?
A: No — FBM204 is a thermocouple input module. It is not a direct replacement for RTD wiring. Substitution requires field wiring changes and configuration updates.
Q: What RTD types does FBM203 support?
A: Pt100, Pt200, Pt500, Pt1000 in 2-, 3-, and 4-wire configurations. Ni100 and Cu10 may be supported depending on firmware revision.
Q: Do you provide a test report?
A: Yes. A functional test report and certificate of conformance are available upon request at no additional charge.
Q: What is the lead time?
A: In-stock units ship within 1–3 business days. Out-of-stock items typically have a 2–4 week sourcing lead time.
