Product Overview
The Foxboro P0923DG is an I/A Series power cable associated with the 24 V DC power supply connection in Foxboro industrial control systems. It connects the DC input terminal block to the compatible P0922YC power supply, supporting the electrical connection required by the power-supply assembly.
With a cable length of 0.8 meters, the P0923DG accommodates installations where the terminal block and power supply are positioned within a relatively short wiring distance. Its role is specific to the power-input connection, so it should not be confused with cables that distribute power from a supply to fieldbus module baseplates or with signal and termination cables used for field I/O.
When replacing this cable, verify the power-supply model and terminal-block arrangement. The P0923DG designation identifies a particular cable configuration, and a cable intended for a different power-supply input or output connection should not be substituted based on length alone.

Product Features
- Dedicated power connection: Connects the DC input terminal block to the associated power-supply assembly.
- 0.8-meter cable length: Supports compact cabinet arrangements with a short connection distance.
- I/A Series integration: Serves as a connection accessory within compatible Foxboro control-system power hardware.

- Simplified cabinet wiring: Provides a defined cable assembly rather than requiring a field-fabricated connection.
- Maintenance replacement: Can be used as a replacement when the installed system specifies this cable configuration.
- Power-system separation: Keeps the power-input connection distinct from fieldbus baseplate power-distribution and signal-wiring connections.
Working Principle
The P0923DG carries the DC power-input connection between the applicable terminal block and the compatible power supply. Once correctly connected, the cable establishes the intended electrical path for the supply input, allowing the power-supply assembly to operate according to its specified electrical requirements.
The cable itself does not regulate voltage or perform power conversion. Those functions belong to the power-supply unit. The cable’s role is to maintain the correct connection between the designated interfaces, so the part number, connector arrangement and wiring assignments must match the installed equipment.
During installation or replacement, the power source must be isolated in accordance with site procedures. The connector condition and cable routing should be checked before energizing the assembly to reduce the risk of loose connections, damaged conductors or incorrect wiring.
Role in a Foxboro I/A Series Power Architecture
The P0923DG is a connection component within the power-input portion of a Foxboro I/A Series installation. It links the designated DC input terminal block to the compatible power supply, while separate power-distribution cables serve the supply-to-baseplate connections.
| System Component | Function | Relationship to the P0923DG |
|---|---|---|
| Foxboro P0923DG | Carries the DC input connection | Connects the designated terminal block to the power supply |
| P0922YC Power Supply | Supplies 24 V DC power | The associated power-supply model for this cable configuration |
| DC Input Terminal Block | Provides the input power connection point | Connects to the power supply through the P0923DG |
| Power Source | Supplies incoming electrical energy | Feeds the input terminal block according to the installation design |
| Power-Supply Output Cable | Distributes power from the supply to compatible baseplates | Serves a separate connection from the P0923DG |
| Fieldbus Module Baseplate | Provides mounting and electrical interfaces for fieldbus modules | Receives power through the designated distribution arrangement |
| Fieldbus Modules | Interface field signals with the control system | Depend on the configured baseplate and power-distribution system |
| Cabinet Wiring Infrastructure | Supports cable routing and equipment organization | Keeps power-input and distribution connections arranged for maintenance |

| Application | Power Connection Requirement | Role of the P0923DG |
|---|---|---|
| Foxboro I/A Series Control Cabinets | Connection between the DC input terminal block and power supply | Provides the specified cable link |
| Process Automation Systems | Organized power wiring for control-system equipment | Supports the power-supply input arrangement |
| Oil and Gas Control Installations | Maintainable connections within process-control cabinets | Connects compatible power hardware |
| Chemical Processing Facilities | Defined wiring between power input and supply assemblies | Supports the specified DC input connection |
| Power Generation Control Systems | Organized control-system power connections | Forms part of the power-supply wiring arrangement |
| Water and Wastewater Automation | Power hardware integration within control cabinets | Connects the designated terminal block and supply |
| Control Cabinet Refurbishment | Replacement of existing power cables | Restores the connection when P0923DG is the specified part |
| Industrial Maintenance and Repair | Replacement of a damaged or worn connection cable | Supports maintenance of a compatible Foxboro power-supply assembly |
Installation and Maintenance
- Verify the cable part number: Confirm that P0923DG matches the cable specified for the installed power supply and terminal-block arrangement.
- Check the power-supply model: Verify the connection requirements for the associated P0922YC power supply before installation.
- Isolate the power source: Follow the site’s electrical isolation and lockout procedures before disconnecting or replacing the cable.
- Inspect the connectors: Check for bent contacts, corrosion, contamination or damage that could affect the electrical connection.
- Confirm connector compatibility: Ensure both cable ends match the intended interfaces without forcing or modifying the connectors.
- Check wiring assignments: Verify the applicable terminal and connector assignments before reconnecting the power circuit.
- Route the cable correctly: Avoid sharp bends, crushing, excessive tension and contact with hot surfaces or moving equipment.
- Maintain cabinet organization: Keep the cable routed so that it does not obstruct access to the power supply, terminal block or adjacent equipment.
- Secure the connection: Ensure the connectors and any applicable retaining hardware are properly seated and secured.
- Avoid unsupported substitutions: Do not replace the P0923DG with a baseplate power-distribution cable or a signal cable solely because the connectors appear similar.
- Inspect after installation: Check the cable jacket, connector seating and routing before restoring power.
- Document maintenance work: Record the installed part number and any connector damage, wiring issues or replacement observations.

Technical FAQs
What does the P0923DG connect in a Foxboro I/A Series installation?
The P0923DG is associated with the DC input terminal block and the P0922YC power supply. It should be distinguished from the separate cables that distribute power from the supply to fieldbus module baseplates.
Is the P0923DG suitable for connecting a power supply directly to a fieldbus baseplate?
That is a different connection function. The P0923DG is used for the specified power-input arrangement, while supply-to-baseplate cables are selected for downstream power distribution. Use the cable type intended for the actual connection points.
What should be checked before replacing a P0923DG with an RH923DG?
Confirm the equipment connection arrangement, the applicable electrical specifications and the replacement designation for the installed system. A related part-number designation should not be treated as sufficient proof of compatibility without matching the required connection details.
What symptoms may indicate a problem with the power cable connection?
Possible signs include intermittent power, unexpected power-supply alarms or visible connector and cable damage. Before replacing the cable, isolate the equipment and check the input source, terminal-block connections, connector seating and power-supply status to distinguish cable faults from other electrical issues.
