More Information

Overview Manuals Dual-Cable Architecture Mounting Commissioning Application
  • Provides the documented dual-cable FCP280 baseplate architecture
  • Accepts one FCP280 or a fault-tolerant processor pair
  • Supports two network adapters and four HDLC/PIO channels

RH100JX is the dual-cable baseplate for supported FCP280 processor installations.

It is selected when the installed node requires the documented dual-cable fieldbus arrangement rather than a standard RH924YL or RH924YF baseplate.

Before replacement, record processor roles, adapter positions, both power inputs, every cable path and the database topology.

Availability, condition, price, and shipping time for RH100JX are confirmed during quotation.

  • Modernization of documented FCP280 dual-cable fieldbus architectures
Description
RH100JX provides the dual-cable mounting and interconnection platform for a supported FCP280 control node.

The baseplate is horizontal, while its DIN rail may be installed horizontally or vertically in the documented arrangement.

Its dual-cable topology and accessories must be preserved when replacing a standard or fault-tolerant processor assembly.

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.
When should Foxboro RH100JX be selected instead of RH924YL or RH924YF?
Select RH100JX only when the documented FCP280 architecture requires dual-cable baseplate connectivity. RH924YL and RH924YF serve standard horizontal and vertical arrangements; confirm the approved topology and cable paths before ordering.
Can Foxboro RH100JX replace a standard FCP280 baseplate without cabling changes?
No direct replacement should be assumed. Foxboro RH100JX uses a dual-cable fieldbus arrangement, so the existing baseplate orientation, A/B cable paths, connectors, terminators, network adapters and control database must all be checked before conversion.
Does Foxboro RH100JX include an FCP280 processor?
Do not assume so. RH100JX is the baseplate; processor modules, network adapters and fieldbus accessories are separate unless explicitly bundled.
Can Foxboro RH100JX use the RH924ZQ time-strobe terminator?
No. Official documentation limits RH924ZQ to the first standard baseplate containing the FCP280 and excludes the dual-cable baseplate.
Why can only one path operate after installing Foxboro RH100JX?
Check both cable routes, connectors, terminators, adapter positions, power feeds and the database definition for the dual-cable topology.
What must be recorded before replacing Foxboro RH100JX?
Record the complete part number, installed processors and adapters, A/B cable paths, terminators, port assignments, grounding, slot positions, saved configuration and active diagnostics before disconnection.
How should Foxboro RH100JX redundancy be tested?
After normal communication is stable, perform controlled transfer and single-path interruption tests while monitoring processor, network and fieldbus diagnostics.
