Schneider Electric documentation shows RH924YF as the 2-position vertical DIN-rail-mounted FCP280 baseplate. Each FCP280 baseplate requires two network adapters, with copper and fiber adapter options documented separately.
Important Specification Note
There are numerous third-party listings that incorrectly describe RH924YF as a digital output module, analog I/O module, or a complete controller. Those descriptions should not be used for engineering approval. The manufacturer’s documentation identifies RH924YF as the baseplate, while the actual processor is RH924YA.
Product Introduction
Foxboro RH924YF Baseplate
The is the vertical DIN-rail baseplate designed to accommodate Field Control Processors in Foxboro DCS installations. It provides the physical mounting and electrical interface for the controller and its network adapters; it does not perform control logic, signal conversion, or I/O processing itself.
The distinction between and RH924YA matters during procurement. RH924YA is the processor, while is its mounting baseplate. Schneider documentation also recommends the vertical-mounted where vertical DIN-rail installation provides more effective cooling around the .

Application Scenarios & Field Pitfalls — Engineer’s Perspective
Engineering Pain Point
usually appears in projects where an controller must be installed in a dedicated vertical DIN-rail arrangement rather than on a conventional horizontal baseplate.
Typical Applications
- Foxboro DCS control cabinets — Mounting Field Control Processors.
- Distributed field control — Supporting controllers communicating with Foxboro FBMs.
- G13/G14 enclosure configurations — Schneider documentation specifically identifies the position for installation.
- Legacy system maintenance — Replacement of damaged or mechanically compromised baseplates.
Technical Pitfalls to Avoid
- Do not order when the failed component is RH924YA.
RH924YA is the actual processor. is the mounting baseplate. - Check the mounting orientation.
is specifically the vertical baseplate. Foxboro also documents a horizontal baseplate, RH924YL. The two should not be treated as mechanically interchangeable. - Verify the network adapters.
Each baseplate requires two network adapters. The documentation identifies fiber and copper adapter choices, so replacing the baseplate without checking the existing adapter configuration can create an installation problem. - Do not use generic 24 VDC/I/O specifications from reseller listings.
is passive infrastructure for the installation. Claims that it is a 4–20 mA analog module, digital output module, or standalone 24 VDC I/O device are inconsistent with the Foxboro documentation.

Procurement Check
For an replacement, verify these four items against the cabinet drawing:
baseplate + + two network adapters + vertical DIN-rail mounting arrangement.
The most important correction for purchasing is simple: is a baseplate, not the processor and not an I/O module.
