Product Introduction
The Foxboro RH101KF is the dedicated two-position baseplate for the Field Device Controller. It is not an I/O module and does not perform control logic by itself. Its job is to provide the physical and electrical platform into which controller modules are installed, including the connections required for power, communications, serial field-device interfaces, and time synchronization.
The two-position design is particularly important in fault-tolerant installations. Schneider Electric states that a fault-tolerant uses two processor modules with interconnecting fault-tolerant communication integrated into the baseplate. The controller modules must occupy the dedicated positions to maintain the intended architecture and cooling arrangement.

Engineering Pain Point
The main replacement risk with RH101KF is treating it as an ordinary passive mounting plate. It is part of the system architecture and establishes the electrical and communication interface between the controller modules and the field-device/network hardware. A physically similar Foxboro 200 Series baseplate should not be substituted simply because it fits the cabinet. Schneider’s documentation specifically excludes RH101KF from the general 200 Series baseplate family and identifies it as the dedicated baseplate.
Typical Applications
- Foxboro field-mounted controller installations
- Single controller configurations
- Fault-tolerant installations using two controller modules
- Direct integration of PLCs, drives, and other distributed field devices
- Foxboro DCS installations requiring Ethernet and serial field-device interfaces
Technical Pitfalls to Avoid
- Do not confuse with RH101FQ. is the baseplate; RH101FQ is the documented module part number.
- Do not substitute a standard 200 Series baseplate. Schneider explicitly identifies as the dedicated baseplate.
- Check whether the application is simplex or fault-tolerant. A fault-tolerant installation requires two modules and the appropriate baseplate arrangement.
- Verify network-adapter revisions. The documentation specifies RH924WA Rev. E or later for fiber and RH924UQ Rev. D or later for copper applications.
- Check cabinet orientation and cooling. Schneider’s installation documentation specifies the baseplate arrangement and mounting orientation requirements associated with controller cooling.
- Do not assume the baseplate contains the controller. is the mounting/interconnection assembly; the controller modules are separate components.

Procurement Note
For a replacement order, specify as the , not as an controller module. Confirm whether the existing system uses one or a two-module fault-tolerant arrangement, then verify the installed network adapters, serial termination hardware, cable lengths, and controller revision.
The key distinction is:
= controller
RH101FQ = documented module part number
= dedicated 2-position baseplate
That distinction should be preserved on the purchase order and during cabinet-level replacement work.
