More Information

Overview Manuals Input Behavior Termination Selection Diagnostics Application
  • Check RH914TD rather than relying on the shared FBM207 family name
  • Do not confuse RH914TD with RH914WH for FBM207b
  • Match the installed voltage-monitor TA before reconnecting field power

Foxboro RH914TD is the exact module part number assigned to the FBM207 voltage-monitor function.

It accepts sixteen isolated DC status inputs through a separately selected termination assembly and Type 4 cable.

Before installation, compare the original label, slot, TA, cable, channel voltage and database definition with the replacement.

Availability, condition, price, and shipping time for RH914TD 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.

  • Sixteen channels are isolated and independent
  • Voltage-monitor operation distinguishes documented on and off states
  • Configurable debounce supports noisy contact or voltage circuits
  • TA choice must match voltage range and field-excitation method
  • Type 4 cables connect the module baseplate to DIN-rail TAs
  • Redundant installations use the documented adapter and adjacent slots
  • Test channel isolation before reconnecting unknown field circuits
  • Compare terminal voltage with the database state during troubleshooting
  • Validate filter timing and safe logic after replacement
  • DC field-voltage status monitoring
  • Isolated discrete-state acquisition
  • Redundant status-input service with the documented adapter
Description
Foxboro RH914TD monitors sixteen independent 15–60 VDC on-state circuits and reports their states to its associated control processor.

The module provides per-channel isolation and configurable debounce, enabling field-status monitoring in electrically diverse process circuits.

It is selected for voltage-present/voltage-absent status acquisition rather than for the internally excited contact-sense service of other FBM207 variants.

Technical notes
RH914TD is the exact FBM207 module part number. RH914WH identifies FBM207b and must not be entered as an alternative name or used as a like-for-like substitute.

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.
Can Foxboro FBM207 RH914TD directly replace the earlier P0914TD?
Foxboro FBM207 RH914TD officially supersedes P0914TD, but confirm the existing termination assembly, Type 4 cable, field-voltage arrangement, baseplate position and saved input configuration before replacement.
Is Foxboro FBM207 RH914TD interchangeable with RH914WH?
No. Foxboro FBM207 RH914TD is the FBM207 voltage-monitor module, while RH914WH is an FBM207b contact-sense module that uses a different field-excitation arrangement.
Can dry contacts be connected directly to Foxboro FBM207 RH914TD without an external field-voltage source?
No. Foxboro FBM207 RH914TD monitors externally supplied field voltage; a dry-contact application requiring module-supplied contact wetting must use the appropriate contact-sense module and termination hardware.
Why might one input on Foxboro FBM207 RH914TD repeatedly change between on and off?
Check for marginal field voltage, excessive source resistance, loose terminals, electrical noise, poor grounding, cable coupling and unsuitable input debounce settings before replacing Foxboro FBM207 RH914TD.
Why can Foxboro FBM207 RH914TD appear online while all field inputs remain inactive?
Verify the external field-voltage source, termination assembly, Type 4 cable seating, common connections, input polarity and configured voltage thresholds for Foxboro FBM207 RH914TD.
What information should be recorded before replacing Foxboro FBM207 RH914TD?
Record the baseplate slot, termination assembly and cable numbers, terminal map, external field-voltage source, channel assignments, debounce settings, active faults and control-logic references for Foxboro FBM207 RH914TD.
How should Foxboro FBM207 RH914TD be tested before returning it to service?
Apply or observe known on and off voltages at every Foxboro FBM207 RH914TD channel, compare field states with the control-system database, verify debounce and diagnostics, and then prove the affected alarms and interlocks under controlled conditions.
