More Information

Overview Manuals Port Flexibility Redundant Paths Troubleshooting Application
  • Supports any documented FCP280 fieldbus port
  • Separates redundant A and B signal paths
  • Terminates the selected baseplate fieldbus connection

RH928CY is the any-port fieldbus terminator/splitter for supported FCP280 baseplates.

It is chosen when a fieldbus port other than the port-1-specific RH924ZJ arrangement requires separate A/B cable paths and termination.

Before replacement, record the selected port, both cable paths, termination point and downstream baseplate chain.

Availability, condition, price, and shipping time for RH928CY 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.

  • Can be used on any documented FCP280 fieldbus port
  • Must remain associated with the configured port
  • Avoid confusing it with the port-1-specific RH924ZJ
  • Separates A and B fieldbus signals
  • Supports separate outgoing fieldbus cables
  • Maintains the documented termination point
  • Check selected port and cable labels
  • Inspect shielding and connector seating
  • Compare both paths and fieldbus diagnostics
  • Any-port redundant fieldbus fan-out on standard FCP280 baseplates
  • Termination of selected FCP280 fieldbus channels
  • Expansion of documented A/B fieldbus cable paths to downstream baseplates
Description
RH928CY separates redundant A and B fieldbus paths from any supported FCP280 baseplate fieldbus port.

It provides the required termination at the selected port while allowing the two paths to continue on individual cables.

Selection depends on the actual port, topology and installed splitter/terminator scheme rather than appearance alone.

Technical notes
Foxboro RH928CY is the any-port FCP280 fieldbus terminator/splitter, distinct from port-1 RH924ZJ. Match the port, A/B cables and downstream topology before replacement.

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 RH928CY be replaced without interrupting fieldbus communications?
Only when the documented redundant topology and approved maintenance procedure allow the unaffected path to remain in service. Verify path health, alarms, process impact and cable identification before disconnecting RH928CY.
Can Foxboro RH928CY be moved to another FCP280 port?
Only after the physical cabling and database references are updated and the new port is verified against the official topology.
Are outgoing cables supplied with Foxboro RH928CY?
Do not assume so. Confirm the quoted stock contents and the exact A/B cable types and lengths required by the installation.
Can Foxboro RH928CY be used on an RH100JX dual-cable baseplate?
Do not assume compatibility; verify the dual-cable baseplate accessory diagram because its fieldbus topology differs from a standard baseplate.
Why can Foxboro RH928CY show healthy on one path but not the other?
Inspect the failed path's connector, polarity, shield, termination, cable continuity and downstream device chain, then compare diagnostics for both paths.
What should be documented before replacing Foxboro RH928CY?
Record the exact baseplate port, A/B cable labels, termination, downstream topology, fieldbus rate and current diagnostics.
How should Foxboro RH928CY be commissioned?
Verify both paths from the selected port through the downstream chain, confirm correct termination and test controlled single-path interruption and recovery.
