Product Overview
The Foxboro RH916FK I/A Series 200 Type 4 P/PVC Termination Cable is an industrial control-system cable associated with Foxboro I/A Series 200 equipment. It is used to establish the required electrical connections between compatible system components, supporting signal transmission within an installed control architecture.
In process automation systems, termination cables help connect field interface equipment, termination assemblies, and control-system hardware according to the system’s wiring arrangement. Correct cable selection is important because the connection must match the intended interface, signal requirements, and termination points. An incorrect cable or wiring arrangement can result in communication faults, missing signals, or difficulties during commissioning.
The RH916FK is identified as a Type 4 P/PVC termination cable. When integrating it into an existing I/A Series installation, engineers should verify the cable’s intended connection points and wiring configuration before installation. Its role is determined by the equipment interfaces and termination scheme used in the specific control system.

Working Principle
The RH916FK functions as a physical electrical connection between designated points in a control system. The conductors carry the electrical signals required by the connected equipment, while the cable’s termination arrangement establishes the intended connection between interfaces.
In a process-control installation, a cable of this type may form part of the wiring between control-system hardware and a compatible termination point. The connected devices determine the signal type and operational behavior; the cable provides the electrical path needed for those signals to pass between the designated connections.
During operation, the integrity of the conductors and terminations affects signal continuity. Loose connections, damaged insulation, incorrect pin assignments, or an unsuitable replacement cable can interrupt the electrical path and create faults that appear elsewhere in the control system.
A simplified connection path is:
Foxboro Control-System Equipment → RH916FK Termination Cable → Designated Termination Interface → Connected Control-System Hardware
The actual connection points and signal assignments depend on the installed equipment and its wiring configuration.
Role in an I/A Series 200 Control Architecture
Within an I/A Series 200 control architecture, the RH916FK provides a cable connection between the designated interfaces for which this termination cable is specified. It supports the physical wiring layer that allows compatible control-system components to exchange the required electrical signals.
| Control-System Component | Function | Relationship to the RH916FK |
|---|---|---|
| I/A Series 200 Control Hardware | Executes control and process-related functions | Connects through the applicable wiring interface |
| Termination Assembly | Organizes electrical connections between system components | Provides the designated termination point where applicable |
| RH916FK Termination Cable | Carries electrical signals between specified connection points | Establishes the physical connection required by the wiring arrangement |
| I/O Interface | Exchanges signals between the control system and connected equipment | May be connected through the relevant termination arrangement |
| Field Instrumentation | Measures process conditions or provides control signals | Participates in the signal path when included in the configured system |
| Control Cabinet | Houses control hardware and wiring assemblies | Provides the installation environment for the cable and connected components |
| System Wiring Documentation | Defines connection points and signal assignments | Supports correct cable installation and troubleshooting |
The cable’s position in the architecture should be determined by the specific hardware configuration. During replacement, preserving the original connection arrangement and confirming the required termination points helps avoid wiring errors and unnecessary commissioning work.

| Oil and Gas Facilities | Control-system wiring in process equipment installations | Can be used where the applicable termination configuration calls for this cable |
| Power Generation | Electrical signal connections within control-system cabinets | Supports the designated wiring path |
| Water and Wastewater Treatment | Connections between process-control hardware and related interfaces | Provides the physical cable connection where specified |
| Industrial Control Cabinets | Internal interconnection of control-system components | Maintains the intended wiring arrangement |
| Control-System Maintenance | Replacement of a damaged or worn cable | Provides a matching replacement when the model and connection requirements are verified |
| Existing I/A Series Installations | Continued operation of established control-system configurations | Supports maintenance of the original cabling arrangement |
Installation and Maintenance
- Confirm the cable model. Check that RH916FK matches the required cable designation in the existing control-system installation.
- Identify the connection points. Determine the intended source and destination interfaces before disconnecting or installing the cable.
- Review the wiring arrangement. Check the applicable wiring diagram, connector assignments, and termination layout to avoid incorrect connections.
- Apply electrical safety procedures. Follow the site’s isolation and work-permit procedures before handling control-system wiring.
- Inspect the cable before installation. Check the outer jacket, connectors, and accessible termination points for damage or contamination.
- Verify connector compatibility. Ensure that the cable ends match the designated equipment interfaces and can be secured correctly.
- Route the cable appropriately. Avoid sharp edges, excessive bending, crushing, and unnecessary mechanical tension.
- Separate wiring where required. Maintain appropriate separation from power conductors and other potential interference sources according to the installation requirements.
- Secure the terminations. Confirm that connectors or terminal connections are fully seated and secured according to the applicable hardware arrangement.
- Check continuity when necessary. If the cable is being installed as a replacement or a fault is suspected, perform suitable continuity and wiring checks with the circuit safely isolated.
- Test the connected system. After installation, verify that the relevant signals or system functions operate as expected and that no new wiring faults have appeared.
- Record the maintenance work. Document the cable replacement, connection points, inspection results, and any changes made to the wiring arrangement.
If a signal fault occurs after installation, check the cable seating, connector condition, conductor continuity, and termination assignments. Confirm that the replacement cable matches the required configuration before investigating more complex control-system issues.
