More Information

Overview Manuals Contact Selection Filtering & Events Field Validation Application
  • Use FBM207B only for its documented 16-channel isolated 24 VDC contact-sense input function
  • Confirm the exact module identity, termination hardware and cable before replacement
  • Preserve field wiring, channel configuration, diagnostics and control state before removal

Foxboro FBM207B is a 16-channel isolated 24 VDC contact sense input module for discrete status, event and pulse acquisition in Foxboro DCS systems.

The official current document styles the function as FBM207b; RH914WH is the current module part number and P0914WH is the documented superseded part number.

Before replacement, verify the exact label, termination hardware, cable, signal limits, field wiring, saved configuration and supported system environment.

Availability, condition, price, and shipping time for FBM207B are confirmed during quotation.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.

  • Use only passive contacts or compatible switches rated for 24 VDC excitation
  • Keep ON resistance at or below 1.0 kΩ and OFF resistance at or above 100 kΩ
  • Confirm the exact suffix because the excitation level is variant-specific
  • Restore the documented per-channel debounce selection
  • Use no filtering only when the source and noise environment permit
  • Coordinate pulse counting and event timing with the control database
  • Exercise every contact from open to closed at the field terminal
  • Apply a traceable pulse source where counting is configured
  • Verify isolation, alarms, sequence behavior and channel diagnostics
  • 24 VDC-wetted passive-contact status acquisition
  • Isolated solid-state switch input acquisition
  • Pulse counting, sequence-of-events and event-status input service
Description
Foxboro FBM207B is a 16-channel isolated 24 VDC contact sense input module for discrete status, event and pulse acquisition in Foxboro DCS systems.

Its documented channel architecture, signal limits and diagnostics support model-specific Foxboro DCS field I/O service without changing the official identity of FBM207B.

Before installation, verify the complete nameplate, order-number relationship, termination hardware, cable, field power, saved configuration, grounding and system compatibility.

Technical notes
FBM207B uses current module part RH914WH, replacing the earlier P0914WH part number. Before replacement, confirm the termination assembly, cable, and whether the RH926ZY redundant adapter is installed.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Is FBM207B suitable for 48 VDC contact circuits?
No. FBM207B uses 24 VDC ±15% contact excitation. Confirm the field-device voltage rating before replacement.
Can FBM207B accept contacts with separate field references?
Yes. Its 16 channels are isolated from one another and from ground, but all connected devices must support 24 VDC excitation.
Can FBM207B monitor pulse signals as well as contact status?
Yes. FBM207B supports contact-status monitoring and pulse counting from 0 to 250 Hz.
How can contact bounce or false transitions be reduced on FBM207B?
Select the appropriate FBM207B debounce setting: no filtering, 4 ms, 8 ms, 16 ms or 32 ms.
Is the RH926ZY adapter required for every FBM207B installation?
No. RH926ZY is an optional redundant adapter. Its use depends on the installed system architecture and termination arrangement.
Why might an FBM207B channel remain in the closed state?
Check the field voltage, terminal shorts, contact resistance, grounding, debounce setting and channel wiring.
What should be checked before replacing FBM207B?
Verify the complete model label, 24 VDC excitation, termination hardware, adapter, channel configuration, field wiring and saved debounce settings.
