Product Overview

The Foxboro RH100CL Cable is an industrial control-system cable designed for compatible Foxboro distributed control system (DCS) installations. It is identified as a 2-meter Type 4 P/PVC cable used to connect a system baseplate to a main termination assembly. This connection supports the organized routing of field signals between the control-system hardware and its associated termination equipment.

In industrial automation, cable assemblies are essential to reliable signal transmission and system integration. A correctly selected cable helps establish the electrical connection between compatible modules, termination assemblies, and other designated control-system components. Cable length, connector configuration, insulation material, and compatibility with the installed hardware all affect whether a particular assembly is suitable for an application.

The RH100CL provides a nominal cable length of 2 meters, making it useful where the distance between the relevant baseplate and termination assembly is within the specified routing range. Selecting the correct length helps maintain organized cabinet wiring while avoiding unnecessary excess cable or mechanical strain on connectors.

The RH100CL is part of a family of Foxboro termination cables available in different lengths and material configurations. It is important not to confuse this P/PVC version with the alternative LSZH cable variants, which have different part numbers and material characteristics.

For industrial maintenance teams, the complete part number should be checked against the existing system documentation before ordering a replacement. A cable that looks similar may have a different length, connector arrangement, or intended application.

Function and Working Principle

The RH100CL provides a physical electrical connection between compatible components in a Foxboro control system. Its function is determined by the system architecture and the hardware to which it is connected.

1. Baseplate-to-Termination Assembly Connection

A DCS installation may use termination assemblies to organize field wiring and connect it to the control-system hardware. The RH100CL is identified for the connection between a baseplate and a main termination assembly in supported configurations.

The cable establishes the designated electrical paths between these components. Correct installation helps ensure that the signals follow the intended route through the control system.

2. Signal Path Support

Industrial control systems rely on dependable electrical connections for monitoring process variables and coordinating equipment. Depending on the connected hardware, signal paths may carry information associated with digital inputs, analog measurements, or control outputs.

The cable itself does not perform signal processing or control logic. Those functions are handled by the relevant modules and controller. Its role is to provide the specified interconnection required by the system design.

3. Cable-Length Selection

The RH100CL has a nominal length of 2 meters. This length should be considered alongside the physical positions of the baseplate and termination assembly, the permitted routing path, and the required service clearance.

The selected cable should reach the intended connectors without excessive tension, sharp bends, or unnecessary routing near sources of electrical interference.

4. Insulation and Jacket Protection

The specified P/PVC construction uses a polyurethane outer jacket and semi-rigid PVC primary conductor insulation. These materials form part of the cable’s mechanical and electrical protection system.

The cable must be used within its specified environmental limits. Its material construction should not be interpreted as making the cable suitable for every chemical, temperature, moisture, or mechanical exposure found in industrial environments.

Role in Foxboro DCS Systems

A distributed control system coordinates measurement, monitoring, and control functions across an industrial process. Its reliability depends not only on controllers and I/O modules but also on the interconnections linking the hardware.

1. Control Cabinet Wiring

The RH100CL can support structured wiring between compatible baseplates and main termination assemblies. Correct cable routing helps keep the cabinet organized and makes it easier for technicians to identify connections during maintenance.

An organized cable layout can also reduce the risk of accidental disconnection when nearby components are inspected or replaced.

2. Field Signal Integration

Termination assemblies provide an interface between field wiring and the relevant control-system hardware. The RH100CL supports the designated connection in compatible Foxboro configurations.

The exact signal assignments depend on the modules and termination assemblies in use. Engineers should consult the relevant wiring diagrams rather than infer pin assignments from the cable model alone.

3. Maintenance and Replacement

When a cable becomes damaged, develops an intermittent connection, or must be replaced during a system upgrade, using the correct part number helps preserve the original system configuration.

Maintenance teams should verify the cable’s identification, length, connector type, and intended endpoints before removing the existing assembly.

4. System Expansion

Industrial facilities may add or rearrange control-system equipment as process requirements change. The RH100CL may be suitable for a compatible installation when the required connection and cable length match the system design.

Adding a cable alone does not guarantee compatibility with a new module or termination assembly. The complete hardware arrangement must be checked before expansion work begins.

Industrial Applications

1. Process Automation

Foxboro DCS technology is used in industrial process-control environments where reliable signal acquisition and equipment coordination are important. The RH100CL can support the designated termination connection in compatible installations.

Its suitability depends on the system architecture and the exact termination hardware being used.

2. Chemical and Petrochemical Facilities

Chemical and petrochemical facilities often use distributed control systems to monitor and control complex process equipment. Within compatible Foxboro installations, the RH100CL may be used as part of the internal control-system interconnection.

Environmental conditions must be assessed carefully, especially where cabinets are exposed to heat, corrosive contaminants, or vibration.

3. Power Generation

Power-generation facilities use control systems to monitor operating conditions and coordinate equipment. A compatible termination cable can support the interconnection of designated DCS components used in these systems.

The cable must match the required system configuration and should not be substituted based only on its physical appearance.

4. Industrial Manufacturing

Manufacturing plants may use DCS or related control architectures to coordinate equipment and monitor production processes. The RH100CL can be considered where the installed Foxboro hardware specifies this cable type.

5. Maintenance of Legacy Control Systems

Older control systems may remain in service for many years. Keeping compatible spare cables available can help maintenance teams replace damaged assemblies without unnecessarily changing the existing cabinet design.

Before using a spare cable, verify the part number and connector arrangement against the original installation.

Installation and System Integration

Correct installation helps maintain dependable electrical connections and reduces the risk of avoidable system faults.

1. Confirm the Part Number

Check that the cable is identified as RH100CL. Do not assume that all RH100-series cables are interchangeable. Other variants may use different lengths or jacket materials.

Compare the replacement cable with the original part number and the relevant system documentation.

2. Verify the Connection Points

Confirm that the cable is intended to connect the specified baseplate and main termination assembly. Check both connector ends for compatibility with the installed hardware.

Never force a connector into place. Incorrect connectors or pin assignments can cause connection failures or equipment malfunction.

3. Plan the Cable Route

Route the 2-meter cable along an appropriate path that allows for cabinet access, maintenance, and connector removal. Avoid sharp bends, excessive pulling force, and contact with sharp metal edges.

Keep control-system wiring organized and separate from sources of electrical interference where the installation guidelines require it.

4. Observe Environmental Limits

The published temperature range for the P/PVC construction is −20°C to +80°C. Confirm that the actual installation remains within the specified limits.

The cable should also be protected from mechanical damage, incompatible chemicals, and environmental conditions outside its approved application.

5. Inspect Before Installation

Check the jacket for cuts, crushing, deformation, or other damage. Inspect connectors for bent contacts, contamination, corrosion, or broken locking features.

Do not install a cable with damaged insulation or questionable connectors in a critical control-system connection.

6. Test the Connection

Follow the site’s approved maintenance procedures before disconnecting or reconnecting control-system equipment. After installation, verify that the connectors are fully seated and secured.

Where required, perform the appropriate continuity or system diagnostic checks. Confirm that the connected modules operate normally before returning the equipment to service.

Compatible System Components

The RH100CL is intended for use with compatible Foxboro control-system hardware. Exact compatibility depends on the baseplate, termination assembly, and installed system configuration.

These are related system components, not a list of items included with the RH100CL cable. Verify the system bill of materials before procurement.

Alternative Models and Replacement Considerations

The RH100CL belongs to a cable family with multiple lengths and jacket-material options. A replacement should be chosen by matching the complete requirements rather than selecting the nearest-looking cable.

The RH100BQ is a 2-meter LSZH variant, not simply another name for RH100CL. LSZH material is designed to limit smoke and halogen emissions under specified fire conditions, while P/PVC has different material characteristics. Any substitution should be approved against the installation’s requirements.

Before selecting an alternative, compare:

• Required cable length.
• Connector type and pin arrangement.
• Intended connection between system components.
• Cable jacket and insulation materials.
• Environmental temperature limits.
• Applicable installation and fire-safety requirements.
• Existing system documentation and approved part numbers.

A cable with the same length may still be unsuitable if its connectors or intended use differ.
