Allen Bradley 1786-FS200 ControlNet Fiber Optic Cable Assemblies

Applications

The Allen Bradley 1786-FS200 ControlNet Fiber Optic Cable Assembly is intended for fiber-optic communication connections in compatible ControlNet industrial automation systems. With a specified cable length of 200 meters, it is suited to installations requiring longer cable runs between network connection points.

• Industrial Network Communication: Supports fiber-optic connections within compatible ControlNet network architectures.

• Distributed Control Systems: Helps connect network equipment installed in separate control cabinets or operating areas.

• Manufacturing Facilities: Provides a cabling option for automation systems spread across production lines and industrial workspaces.

• Electrically Noisy Environments: Fiber-optic communication can reduce susceptibility to electromagnetic interference and provide electrical isolation between connected equipment.

• Control Network Expansion: Can be considered when extending an existing fiber-optic communication layout.

• Maintenance and Replacement: Offers a replacement option for installations that specifically require the 1786-FS200 model.

Advantages

1. Extended Cable Reach

The 200-meter cable length offers greater routing flexibility for installations where network components are located a considerable distance apart.

2. Fiber-Optic Signal Transmission

Fiber-optic cabling is useful in environments where electrical noise, grounding differences, or isolation requirements make optical communication advantageous.

3. Support for Distributed Equipment

The cable length can accommodate network layouts that span multiple equipment areas, subject to the capabilities of the connected devices and the overall network design.

4. Reduced Electromagnetic Interference Sensitivity

Unlike copper communication cables, fiber-optic cables do not conduct electrical signals along the fiber. This can help reduce communication issues associated with electromagnetic interference.

5. Flexible Industrial Installation

A longer assembly can simplify cable routing through designated trays, pathways, and equipment areas when the installation distance is known in advance.

6. Useful for System Maintenance

Using the specified model for a replacement can help maintain compatibility with an existing installation, provided the connector configuration and fiber requirements match.

Technical FAQs

Q1: What is the primary purpose of the Allen Bradley 1786-FS200?

The 1786-FS200 is a ControlNet fiber-optic cable assembly intended to provide an optical communication connection in compatible industrial network installations.

Q2: What is the cable length of the 1786-FS200?

The specified cable length is 200 meters, equivalent to approximately 656.17 feet.

Q3: Why choose fiber-optic communication for industrial automation?

Fiber-optic communication can provide electrical isolation and reduce susceptibility to electromagnetic interference. These characteristics are beneficial in some industrial environments containing motors, variable-frequency drives, and other sources of electrical noise.

Q4: Can this cable be used with any ControlNet device?

No. The connected devices must support the appropriate fiber-optic interface and network arrangement. Confirm connector type and compatibility with the installed hardware before use.

Q5: Does the cable itself require electrical power?

A passive fiber-optic cable does not require a separate electrical power supply to carry optical signals. The active communication equipment connected at each end must be powered according to its own specifications.

Q6: What should be considered when installing a 200-meter fiber-optic cable?

Plan the route to avoid excessive bending, crushing, abrasion, and tension. Also verify that the cable type and connected network equipment support the intended link distance.

Q7: Can the 1786-FS200 replace a copper ControlNet cable?

It should not be considered a direct plug-in replacement for coaxial ControlNet cabling. Fiber-optic and coaxial installations use different physical interfaces and may require different network hardware.

Q8: What could cause communication problems after installation?

Possible causes include damaged fiber, contaminated connectors, excessive optical loss, incompatible interfaces, or problems with the associated network equipment. Check the cable path and connection points before troubleshooting the wider network.

Q9: Is the cable suitable for outdoor installation?

Outdoor suitability should not be assumed from the model number alone. Verify the cable's environmental rating and the requirements of the installation before routing it outdoors or exposing it to moisture, sunlight, or extreme temperatures.

Q10: What should be verified before purchasing a replacement?

Check the full model number, required cable length, connector arrangement, fiber specifications, and compatibility with the existing ControlNet equipment. These details help ensure the replacement matches the intended application.
