51195479-600 Honeywell C300 PM I/O 8-Drop Cable Assembly

Product Overview

Honeywell 51195479-600 is an Experion PKS PM I/O Link Cable Set. It connects a C300 Controller IOTA to PM files containing PM I/O Processors (IOPs).

This assembly provides an 8-drop multidrop communication connection over the 375 KBaud PM I/O Link. It supports communication between the C300 controller and distributed PM I/O equipment.

The cable assembly provides a passive communication path. It does not contain active communication electronics or built-in communication ports. Redundant installations require separate A and B cable paths.

Technical Specifications

Communication Architecture and Performance

The 51195479-600 provides the physical communication path between the C300 Controller IOTA and PM I/O equipment.

• Communication Speed: The PM I/O Link operates at 375 KBaud.
• Link Capacity: Each I/O Link supports up to 40 I/O Units under the specified 50 ms CEE configuration.
• Data Throughput: The documented performance reaches 1,000 Link Units per second.
• Parameter Access: Each Link Unit represents one parameter read or write per second.
• Controller Resources: One C300 controller provides two PM I/O Links.
• Physical Connection: The cable assembly supports eight drops.

Important: The two controller links are identified as IOL1 and IOL2. Their cable identification uses different colors.

Redundancy and System Configuration

Honeywell uses separate A and B communication paths for redundant PM I/O Link configurations.

• Use the A and B cable paths for the required redundant architecture.
• Maintain consistent link identification during cabinet installation.
• Verify IOL1 and IOL2 assignments before connecting the cables.
• Check the controller configuration against the installed PM I/O topology.
• Do not treat one cable path as a complete redundant pair.

The A+B configuration supports communication-path redundancy. Actual system redundancy also depends on the complete controller, interface, and cabinet configuration.

Installation Guidelines

Correct cable routing and link identification help maintain reliable PM I/O communication.

1. Verify the Hardware: Confirm the cable model and the target C300 Controller IOTA.
2. Check the Adapters: Prepare the required 51202341-112 adapter pair at the C300 IOTA end.
3. Identify the Link: Confirm the IOL1 or IOL2 assignment before installation.
4. Plan the Drops: Match all eight cable drops with the approved PM file layout.
5. Install the Cable: Follow the cabinet wiring drawings and Honeywell installation instructions.
6. Check Redundancy: Install both A and B paths when the system requires redundant communication.
7. Inspect Connections: Check cable routing, termination, and connection security.

Installation Note: Honeywell does not publish a fixed overall harness length for this assembly. Determine the required routing length from the actual cabinet layout.

Commissioning and Maintenance

Commissioning should verify the complete communication path before process operation.

• Hardware Verification: Confirm the C300 IOTA, adapter pair, and PM file connections.
• Link Identification: Check the IOL1 and IOL2 assignments against engineering drawings.
• Communication Testing: Verify PM I/O Link communication at 375 KBaud.
• Drop Verification: Confirm that all configured PM I/O drops communicate correctly.
• Redundancy Testing: Test A and B communication paths according to the approved procedure.
• Signal Diagnostics: Review controller diagnostics and PM I/O communication status.

For routine maintenance, inspect cable connections and routing during scheduled cabinet inspections. Investigate communication faults before replacing the complete cable assembly.

Compatibility and Application

The Honeywell 51195479-600 is intended for compatible Experion PKS Series C installations.

Primary Compatibility:

• Honeywell C300 Controller IOTA
• Honeywell PM files containing PM IOPs
• Experion PKS PM I/O Link architecture
• 375 KBaud PM I/O communication networks
• Compatible 51202341-112 IOTA adapter pair

Typical Applications:

• Distributed process control systems
• Industrial I/O communication cabinets
• Process automation infrastructure
• Honeywell Experion PKS system integration
• Redundant PM I/O communication installations

Always verify the controller generation, IOTA hardware, PM IOP configuration, and system revision before ordering.

Certifications and System Compliance

The Honeywell Series C platform references the following system-level standards:

• EN 61326-1:2013: Electromagnetic compatibility requirements for electrical equipment.
• IEC/EN 61010-1: Safety requirements for electrical measurement, control, and laboratory equipment.

These standards apply to the documented Series C platform and its certified cabinet assembly. They do not establish separate product-level certification for the 51195479-600 cable set.

Packaging and Supply Scope

The product identification specifies an eight-drop PM I/O Link cable set.

• Honeywell 51195479-600 PM I/O Link Cable Set
• Eight-drop multidrop cable assembly
• A+B cable paths where specified by the ordered redundant configuration

Ordering Note: Confirm the required A/B configuration and 51202341-112 adapter requirements before purchase. The adapter pair is a separate interface requirement and is not assumed to be included.

Frequently Asked Questions

1. What should engineers verify before replacing a 51195479-600 cable set?

Check the existing link assignment, drop arrangement, and cabinet wiring drawings. Also verify the adapter interface and A/B redundancy requirements. Matching the part number alone does not confirm complete installation compatibility.

2. Can one 51195479-600 cable set provide redundant communication?

Do not assume that one cable path provides complete redundancy. Honeywell's redundant PM I/O Link architecture requires separate A and B paths. Confirm the required cable quantity against the system design.

3. Does the cable set include the 51202341-112 adapters?

The available technical description identifies these adapters as a separate interface requirement. It does not confirm their inclusion in the cable set. Check the supplier's packing list before ordering.

4. How should buyers determine the correct cable length?

Use the actual cabinet layout and approved wiring drawings. Honeywell does not publish a fixed harness length for this model. Avoid selecting a replacement based only on an aftermarket listing's stated length.

5. What information should buyers provide when requesting a quotation?

Provide the full model number, required quantity, C300 IOTA details, PM IOP configuration, and redundancy requirements. Photos of existing labels and wiring connections can also help confirm the correct replacement.
