Product Overview
The Foxboro P0923NG I/A Series 200 Power Supply Y-Cable is a power distribution accessory for compatible FPS400-style power supplies used in Foxboro Standard 200 Series control systems. Unlike a conventional power supply output cable with a single connection path, this Y-cable branches the power connection to provide additional physical connections for multiple baseplates.
The P0923NG has a cable length of 0.5 meters. It addresses a specific cabinet installation constraint: when all six available power connections on an FPS400-style supply are occupied, the Y-cable can extend the connection arrangement using existing Foxboro three-pin power cables. Its pin connection attaches to the power supply, while the socket branches connect to the cables leading to the baseplates.
This arrangement is useful when expanding an existing distributed control system without relocating the installed power supply. For example, a control cabinet may require additional baseplate connections after more fieldbus modules are added. The Y-cable provides another physical connection path, but the expansion must remain within the power supply’s rated capacity and the applicable system configuration.
The P0923NG is the earlier part reference; RH923NG is the corresponding later reference. Both are associated with the same 0.5-meter Y-cable application. During replacement, the connector arrangement and power supply compatibility matter more than cable length alone.

Working Principle
The P0923NG branches the power connection from an FPS400-style power supply into additional physical connection paths. The pin end connects to the supply, while the socket ends connect to compatible three-pin power cables that continue to the baseplates.
In a cabinet with several modular baseplates, the number of available supply connections can become a practical limitation before the power supply itself reaches its electrical capacity. The Y-cable addresses that connection constraint by allowing existing power cables to be connected through a shared branching arrangement.
For example, when an additional baseplate is introduced into an established control cabinet, the installer may be able to use the P0923NG to accommodate the required connection without replacing the entire power distribution arrangement. Whether this is permissible depends on the supply’s output ratings, the connected equipment and the applicable installation instructions.
The cable does not increase the power supply’s rated output. It creates additional physical connections only. The combined load must remain within the specified electrical limits, and the complete arrangement must be checked for compatibility before the system is energized.
Role in a Foxboro I/A Series 200 Control System
The P0923NG sits between an FPS400-style power supply and the existing three-pin power cables that connect to compatible baseplates. Its purpose is to expand the available connection arrangement rather than perform power conversion or control processing.

Installation and Maintenance
- Verify the part reference: Confirm that P0923NG or the corresponding RH923NG reference matches the required Y-cable configuration.
- Check power supply compatibility: Identify the installed FPS400-style power supply and verify that the connection arrangement supports the cable.
- Isolate the power supply: Follow the system’s shutdown and electrical isolation procedures before installing or removing the cable.
- Inspect the connectors: Check the pin and socket contacts for contamination, deformation or mechanical damage.
- Check the existing power cables: Confirm that the three-pin cables connected to the branch outputs are compatible and in serviceable condition.
- Plan the cable route: Position the Y-cable so that the short connection can be made without excessive tension or sharp bends.
- Connect the pin end: Attach the designated pin connection to the power supply interface according to the applicable connection arrangement.
- Connect the branch outputs: Attach the compatible existing three-pin power cables to the socket branches.
- Secure the cable routing: Keep the cable away from sharp cabinet edges, moving parts and sources of unsuitable heat.
- Verify the total electrical load: Check the combined load of the connected baseplates against the power supply’s ratings and applicable system requirements.
- Restore power and check operation: Follow the approved startup procedure and verify that the connected baseplates receive power normally.
- Record the installation: Document the cable reference, connected baseplates, connection arrangement and any issues identified during commissioning.

Technical FAQs
What problem does the P0923NG solve in an FPS400-style installation?
It provides additional physical power connections when the six available connections on the supply are insufficient for the intended baseplate arrangement. It does not increase the power supply’s rated output.
How are the connectors arranged on the P0923NG?
The pin end connects to the power supply, while the socket branches connect to compatible existing three-pin power cables leading to baseplates. The connector arrangement should be checked against the installed equipment before fitting.
Can the P0923NG be used to add more baseplates without checking the power load?
No. The Y-cable expands physical connectivity, not electrical capacity. The combined connected load must remain within the power supply’s specified ratings and the applicable system requirements.
What is the relationship between P0923NG and RH923NG?
P0923NG is the earlier part reference, while RH923NG is the corresponding later reference for the 0.5-meter Y-cable. Replacement selection should still account for the installed connectors and system configuration.
