More Information

Overview Manuals Port Assignment Signal Paths Service Checks Application
  • Dedicated to FCP280 fieldbus port 1
  • Separates redundant A and B fieldbus paths
  • Provides documented fieldbus and optional time-strobe termination

RH924ZJ is the port 1 terminator/splitter for a standard FCP280 baseplate fieldbus connection.

Use it where redundant A/B fieldbus paths must leave the baseplate as separate cables and the port requires proper termination.

Before replacement, label both paths, verify the port number and record any optional time-strobe connections.

Availability, condition, price, and shipping time for RH924ZJ are confirmed during quotation.

Description
RH924ZJ terminates FCP280 fieldbus port 1 while separating the redundant A and B module-fieldbus paths into individual cables.

It also participates in the documented optional time-strobe connection at the standard baseplate.

Port identity, fieldbus topology, termination position and time-strobe wiring must be preserved during 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.
How can I avoid selecting the wrong FCP280 fieldbus interface?
Use RH924ZJ only for the documented FCP280 fieldbus port 1 arrangement. If another port is required, verify whether the RH928CV any-port interface is specified, and confirm the baseplate, A/B paths, connectors and fieldbus type before ordering.
What does Foxboro RH924ZJ do with the A and B fieldbus paths?
It separates the redundant A and B signals from the baseplate into individual cables while providing the required fieldbus termination.
Does Foxboro RH924ZJ replace a fieldbus cable?
No. RH924ZJ is the terminator/splitter at the baseplate; the correct outgoing fieldbus cables remain separate items.
Can Foxboro RH924ZJ be moved from a standard to a dual-cable baseplate?
Do not assume compatibility. Confirm the exact baseplate architecture and accessory diagram because dual-cable baseplates use a different topology.
Why can one path fail after replacing Foxboro RH924ZJ?
Check A/B cable assignment, connector seating, shielding, terminator integrity, fieldbus rate and database path before condemning the accessory.
What should be recorded before removing Foxboro RH924ZJ?
Record the port 1 location, A/B cable labels, termination, optional time-strobe wiring, neighboring accessories and communication diagnostics.
How should Foxboro RH924ZJ be validated after installation?
Confirm both A and B fieldbus paths, termination quality, time-strobe operation where used and recovery after a controlled single-path interruption.
