Product Overview
The Foxboro RH916DF is an I/A Series 200 Type 1 P/PVC termination cable used to connect compatible fieldbus modules with their associated termination assemblies. It is part of the RH916 termination cable family for Foxboro distributed control system field I/O installations.
The RH916DF is the 15-meter configuration in the Type 1 P/PVC cable range. It is used where the termination assembly and fieldbus module require a longer physical connection within the control system installation.
The cable provides a preassembled signal path between the termination assembly and the I/O module, reducing the need for individually wired connections between these two parts of the I/O architecture.
RH916DF supersedes the earlier P0916DF designation. The Type 1 P/PVC construction uses a polyurethane outer jacket and semi-rigid PVC primary conductor insulation, with a specified temperature range of -20 to +80 °C.

Working Principle
The RH916DF serves as the electrical connection between the fieldbus module and the associated termination assembly. It does not perform signal processing or control functions itself.
Field devices are wired to the termination assembly, where the corresponding field circuits are organized and connected to the termination cable. The RH916DF then carries these signals to the fieldbus module.
For input channels, signals from transmitters, sensors, switches, or other field devices travel through the termination assembly and cable to the I/O module for processing. For output channels, signals generated by the control system travel through the same connection in the opposite direction toward the field termination point.
The 15-meter cable length allows the termination assembly and fieldbus equipment to be installed with greater separation while maintaining the required electrical connection within the I/A Series 200 I/O architecture.
Role in an I/A Series 200 Distributed Control Architecture
| System Layer | Typical Component | Role |
|---|---|---|
| Field Device Layer | Sensors, transmitters, switches, actuators | Generates or receives process signals |
| Field Wiring Layer | Field Cables | Connects field devices with termination hardware |
| Termination Layer | I/A Series 200 Termination Assembly | Provides organized field wiring connections |
| Cable Interface Layer | RH916DF | Connects termination hardware with the fieldbus module |
| I/O Layer | I/A Series 200 Fieldbus Module | Processes field input and output signals |
| Control Layer | I/A Series Controller | Executes process control logic |
| Operator Layer | HMI or Operator Workstation | Provides process monitoring and operator control |
Industrial Applications
| Application | Use of RH916DF |
|---|---|
| I/A Series 200 I/O Cabinets | Connects fieldbus modules with termination assemblies |
| Process Control Systems | Carries field signals between termination and I/O hardware |
| Distributed Field I/O | Provides the physical connection within the I/O subsystem |
| Control Cabinet Expansion | Supports additional field I/O installation |
| System Maintenance | Replaces an existing compatible termination cable |
| Extended Cabinet Wiring | Provides a 15-meter connection where greater cable reach is required |
Installation and Maintenance
- Verify system compatibility: Confirm that the fieldbus module and termination assembly are compatible with the RH916DF termination cable arrangement.
- Confirm the cable type: Check that the application requires a Type 1 P/PVC termination cable.
- Inspect before installation: Check the cable jacket, connectors, and connection ends for visible damage.
- Identify the correct connection points: Match the termination assembly with its corresponding fieldbus module before connecting the cable.
- Plan the cable route: Route the 15-meter cable so that it does not interfere with cabinet access or other equipment.
- Avoid excessive bending: Do not sharply bend, twist, or pull the cable during installation.
- Protect the outer jacket: Keep the cable away from sharp edges, moving parts, and other sources of mechanical damage.
- Secure the cable: Use appropriate cable-management methods to prevent unnecessary movement or stress on the connectors.
- Check connector engagement: Make sure both cable ends are fully seated before energizing the associated I/O system.
- Maintain wiring separation: Keep the cable properly routed relative to power circuits and other wiring that may introduce electrical interference.
- Verify signal continuity: Check the relevant I/O signal paths after installation or replacement before returning the system to service.
- Inspect during maintenance: Check for damaged insulation, loose connections, contamination, and mechanical stress during scheduled maintenance.
