More Information

Overview Manuals Replacement Time Strobe Fieldbus Termination Application
  • Installs only on the first standard FCP280 baseplate
  • Connects optional A and B time-strobe signals
  • Provides the documented fieldbus termination function

RH924ZQ is the time-strobe fieldbus terminator for the first standard baseplate containing an FCP280.

It is selected only when the supported control architecture uses the optional A/B time-strobe distribution.

Before installation, verify baseplate type, first-node position, time-strobe wiring and fieldbus termination; do not use it on RH100JX.

Availability, condition, price, and shipping time for RH924ZQ 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.

  • Installs at the first standard FCP280 baseplate
  • Depends on the documented timing topology
  • Is not supported on the RH100JX dual-cable baseplate
  • Connects optional time-strobe path A
  • Connects optional time-strobe path B
  • Requires correct polarity and path identification
  • Terminates the associated fieldbus connection
  • Must match the selected baseplate port
  • Requires post-installation communication checks
  • Optional time-strobe distribution from the first FCP280 baseplate
  • A/B timing-path connection in supported control architectures
  • Fieldbus termination at the timing-source processor baseplate
Description
RH924ZQ terminates the relevant fieldbus connection and connects optional A and B time-strobe signals at the first standard FCP280 baseplate.

Its installation location is constrained by the timing topology and it is not used on the RH100JX dual-cable baseplate.

Before replacement, confirm that the system actually uses time strobe and preserve both timing paths and the fieldbus termination.

Technical notes
Foxboro RH924ZQ belongs only on the first standard FCP280 baseplate and is not compatible with the RH100JX dual-cable baseplate. Preserve both time-strobe paths and fieldbus termination.

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.
What function does Foxboro RH924ZQ provide in an FCP280 system?
RH924ZQ provides the documented time-strobe termination used by compatible synchronized event-timestamping arrangements. It must be installed in the specified first standard baseplate and is not a general-purpose fieldbus terminator.
Can Foxboro RH924ZQ be used with the RH100JX dual-cable baseplate?
No. Foxboro RH924ZQ is intended for standard FCP280 baseplates. RH100JX provides dedicated time-strobe connections and does not use this adapter.
What should be confirmed before ordering Foxboro RH924ZQ?
Confirm that the installation uses a standard FCP280 baseplate, requires optional time-strobe signals, and has the first HDLC port available for the adapter.
Does installing Foxboro RH924ZQ make the first HDLC port unavailable for fieldbus use?
Yes. Foxboro RH924ZQ occupies the first HDLC port on the standard FCP280 baseplate, and that port cannot serve another function in this configuration.
Why can synchronized event timestamps remain incorrect after installing Foxboro RH924ZQ?
Check the external time source, A and B signal assignments, cable continuity, connector seating, grounding, termination and system time-synchronization configuration before replacing Foxboro RH924ZQ again.
What should be documented before replacing Foxboro RH924ZQ?
Record the baseplate model, installed port, A and B time-strobe cable labels, fieldbus connections, termination arrangement and current timing diagnostics so the original topology can be restored accurately.
How should Foxboro RH924ZQ be validated after installation?
Confirm stable fieldbus communication, verify reception through the required time-strobe paths, and compare synchronized event timestamps across the affected FCP280 and connected I/O under controlled conditions.
