Product Overview
The Foxboro P0916UH I/A Series HDLC Cable is a 20-meter cable used in compatible Foxboro I/A Series control-system network configurations. It belongs to the HDLC cable family associated with the interconnection of control-system communication hardware. Its primary purpose is to provide the physical cable connection required by the intended network architecture.
In industrial automation systems, communication cabling connects control hardware and network components so that information can be exchanged between designated interfaces. Selecting the correct cable is essential because HDLC cables, module fieldbus cables, termination cables, and base-to-base cables serve different purposes within the broader control-system infrastructure.
The P0916UH is identified as a 20-meter HDLC cable in Foxboro I/A Series cabling references. Its application should be evaluated against the existing network arrangement, connector requirements, and installed equipment. The cable length alone does not establish compatibility with every communication interface.
For maintenance engineers, the P0916UH is relevant when replacing an existing cable, restoring a communication connection, or maintaining a legacy control-system installation. Confirming the complete part number and the intended connection before installation helps avoid selecting a cable from the wrong product family.

Working Principle
The P0916UH provides the physical cable connection required by its designated HDLC communication arrangement. HDLC, or High-Level Data Link Control, is a data-link protocol used to organize data transmission between compatible communication interfaces. The cable itself does not execute the protocol, process field measurements, or perform control logic.
In a control-system communication arrangement, compatible interfaces transmit and receive data through the established physical connection. The communication hardware handles the applicable signaling and protocol functions, while the cable carries the electrical signals between the designated connection points.
A simplified communication path is:
Control-System Communication Interface → P0916UH Cable → Compatible Communication Interface
The exact equipment connected by the P0916UH depends on the installed Foxboro I/A Series architecture. The cable should therefore be selected according to the original connection arrangement rather than assumed to be suitable for every HDLC or fieldbus interface.
Cable length is another consideration. The 20-meter version is relevant when the specified installation requires that connection distance. Routing should account for the cabinet layout, connection points, and applicable installation practices. A cable with the correct length may still be unsuitable if its connector arrangement or intended interface does not match the system.
When communication problems occur, technicians should inspect the cable, connectors, and connected communication hardware. A loose or damaged connection can interrupt data transmission, but similar symptoms may also result from a fault in the interface hardware, an incorrect connection, or a problem elsewhere in the network configuration.
Role in the Foxboro I/A Series Control Architecture
The P0916UH forms part of the communication cabling infrastructure used in compatible Foxboro I/A Series installations. Its function is to provide the designated physical connection between communication interfaces within the applicable control-system arrangement.
Control-System Hardware → Communication Interface → P0916UH Cable → Compatible Communication Interface → Connected Control-System Hardware
| System Component | Function |
|---|---|
| P0916UH Cable | Provides the designated HDLC cable connection |
| Communication Interfaces | Transmit and receive information through compatible connections |
| Control-System Processors | Execute configured control logic and process system data |
| Network Hardware | Supports communication between connected system components |
| Fieldbus Modules | Interface with process inputs and outputs |
| Termination Assemblies | Connect field wiring to designated fieldbus module interfaces |
| Engineering and Diagnostic Tools | Support configuration checks and communication troubleshooting |
The P0916UH is a passive cable component. Its role depends on the connected interfaces, the installed communication architecture, and the requirements of the specific control-system configuration.
Industrial Applications
| Application | Typical Use |
|---|---|
| Distributed Control Systems | Maintaining communication cabling in compatible I/A Series installations |
| Process Automation | Supporting designated connections between control-system communication interfaces |

| Legacy DCS Support | Maintaining installations that specify the P0916UH cable |
| Control-System Service | Investigating cable-related communication faults |
The suitability of the P0916UH for a particular application depends on the installed communication hardware, connection requirements, and system configuration. Engineers should confirm the original cable specification before replacement.
Installation and Maintenance
- Verify the part number: Confirm that P0916UH is the specified cable for the intended Foxboro I/A Series connection.
- Identify the connected hardware: Determine which communication interfaces the cable connects and verify that the equipment matches the existing system configuration.
- Review system drawings: Check the wiring and network documentation to identify the correct connection points.
- Follow site safety procedures: Apply the appropriate isolation and maintenance procedures before working on control-system hardware.
- Inspect the cable jacket: Check for cuts, abrasion, crushing, cracking, or other visible damage that could affect cable integrity.
- Examine the connectors: Look for contamination, deformation, damaged housings, or other signs of poor connection quality.
- Confirm connector compatibility: Verify that both ends match their designated interfaces before installation.
- Secure the connections: Ensure that the connectors are fully seated and secured according to the applicable equipment instructions.
- Route the cable carefully: Avoid sharp bends, excessive tension, crushing, and contact with sharp cabinet edges.
- Maintain proper cable routing: Follow the installation’s cable-routing practices and avoid unnecessary interference with other wiring.
- Verify communication: After installation, check the connected equipment and available diagnostics to confirm that the expected communication function has been restored.
- Document the replacement: Record the installed part number, connected interfaces, and verification results in the maintenance records.
If communication remains unavailable after replacement, inspect the connection points and associated interface hardware. Review system diagnostics and confirm the correct cable configuration before replacing additional components.

Technical FAQs
What does HDLC mean in the P0916UH product designation?
HDLC stands for High-Level Data Link Control, a data-link protocol used for communication between compatible interfaces. The P0916UH is identified as an HDLC cable, but the exact connected hardware should be confirmed from the installed system documentation.
How should the P0916UH be selected for a replacement installation?
Verify the complete part number, required cable length, connector arrangement, and connected communication interfaces. The original cable specification is the most useful reference for determining whether P0916UH is the correct replacement.
Can the P0916UH replace a Foxboro module fieldbus cable?
Not automatically. An HDLC cable and a module fieldbus cable serve different connection functions. Their connector arrangements and intended interfaces may differ, so replacement should be based on the actual system configuration rather than cable length alone.
What should be checked if communication fails after installing the P0916UH?
Inspect both connectors, confirm that the cable is connected to the correct interfaces, and check the status of the associated communication hardware. If the physical connection is intact, review system diagnostics and investigate the connected interfaces for other possible faults.
