- Use FBM203B only for its documented FBM203B 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 FBM203B
Foxboro FBM203B is an eight-channel isolated 2- or 3-wire RTD input module for resistance-temperature measurement in Foxboro DCS systems.
FBM203B is the functional FBM203B designation; RH922UA is the current module part number; RH916XJ / P0917JM / RH924WN 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 FBM203B are confirmed during quotation.
