- Use FBM201B only for its documented FBM201B function and matched field signal type
- Confirm the exact module order identity, termination assembly and cable before replacement
- Preserve channel configuration, field wiring and diagnostics before removing FBM201B
Foxboro FBM201B is an eight-channel isolated low-level voltage analog input module for Foxboro DCS field measurements.
FBM201B is the functional FBM201B designation; RH922YH is the current electronic-module part number; RH922ZM is separate termination hardware.
Before replacement, verify the exact label, signal range, termination assembly, cable, channel configuration, field wiring and system compatibility.
Availability, condition, price, and shipping time for FBM201B are confirmed during quotation.

- Match the 0 to 100 mV DC source range before wiring
- Keep each isolated channel within its permitted common-mode conditions
- Use traceable references for zero and span checks
- Use the documented RH922ZM termination assembly
- Match compression or ring-lug terminals to the installed wiring
- Keep the Type 1 cable identity and length with the maintenance record
- Restore channel scaling, alarms and engineering units
- Check isolation and shield practice before reconnecting field devices
- Compare module diagnostics with the saved pre-removal state
- Isolated acquisition of low-level voltage field signals
- Retrofit of a like-for-like Foxboro DCS input module with preserved scaling
- Channel-isolated measurements where separate field references must be retained
