Product Overview
The Foxboro P0973CN Extended Backplate is a specialized mechanical and electrical infrastructure component used within Foxboro industrial control-system architectures. Unlike a controller, I/O module, or communication processor, the P0973CN provides the physical mounting and system interconnection structure required to install compatible control-system modules in an organized and expandable configuration.
In a distributed control system (DCS), backplates and base assemblies provide more than simple mechanical support. They establish the physical arrangement for system modules and provide the necessary interconnection between compatible components. An extended backplate can therefore be particularly useful when a control-system installation requires additional module positions or a larger equipment arrangement.
The Foxboro P0973CN is identified as an Extended Backplate and is intended for use as part of a modular Foxboro control-system installation. It can help organize system hardware within a control cabinet while providing the physical foundation for compatible modules.
The supplied dimensions are 240 × 27.1 × 240 mm, with an approximate weight of 0.91 kg. Its relatively shallow profile allows it to occupy a defined mounting position while providing the mechanical structure required for compatible control-system hardware.
Because the P0973CN is an infrastructure component, its compatibility should always be evaluated together with the exact Foxboro system generation, module family, mounting arrangement, and associated hardware.

The backplate establishes the physical relationship between the installed modules and the control-system infrastructure.
Depending on the specific architecture, the backplate may support:
- Module mounting
- Electrical interconnection
- System expansion
- Organized cabinet installation
- Communication infrastructure
- Power distribution between compatible modules
The P0973CN does not independently process signals or execute control logic. Its purpose is to provide the structural and interconnection foundation for other system components.
What Is the Foxboro P0973CN Used For?
The P0973CN is used when a Foxboro control-system installation requires an extended mounting arrangement for compatible system hardware.
Typical reasons for using an extended backplate include:
- Expanding the number of installed modules
- Creating additional mounting positions
- Organizing distributed system hardware
- Building larger control cabinets
- Supporting modular DCS configurations
- Providing a structured equipment installation
- Maintaining consistent module positioning
For large industrial automation systems, the physical organization of control hardware is important. A properly designed backplate arrangement can make installation, wiring, inspection, and future maintenance easier.
Role in Industrial Control Systems
The P0973CN forms part of the hardware infrastructure surrounding the active control modules.
A simplified DCS structure is:

I/O Modules
↓
Control Processors
↓
Communication Modules

Operator and Engineering Systems
The backplate provides the physical mounting foundation for selected components within this architecture.
Its role is therefore different from the role of a control processor such as a Foxboro FCP270.
A processor executes control algorithms.
An I/O module handles field signals.
A communication module transfers information.
A backplate provides the physical and system-level infrastructure needed to mount and interconnect compatible hardware.
This distinction is important when selecting a replacement because a backplate cannot substitute for an electronic control module.
Extended Backplate Architecture
The use of an extended backplate is particularly useful when a system requires more physical space than a standard mounting arrangement provides.
A simplified installation can be represented as:
Existing DCS Hardware
↓
Extended Backplate
↓
Additional Compatible Modules
↓
Expanded Control-System Configuration
This type of architecture allows engineers to expand an existing system while maintaining a structured hardware arrangement.
The backplate can also help ensure that modules are positioned consistently within the cabinet, making future maintenance and equipment identification easier.
