Product Overview
The Honeywell 51202329-301 is a dedicated Series C I/O interconnection cable engineered to interface Series C I/O Modules with Honeywell I/O Termination Assemblies and Panels. It forms the internal signal bridge between the controller electronics and the field termination hardware, ensuring stable power delivery, deterministic data exchange, and continuous diagnostics.
Designed specifically for Honeywell distributed control architectures, this cable supports long-term operation in electrically noisy control cabinets while maintaining mechanical security and signal fidelity.
System Compatibility
The 51202329-301 is validated for use across Honeywell’s core control platforms that deploy Series C I/O technology.
Compatible systems include
Experion PKS control environments
C300 controllers with Series C I/O modules
TPS and TDC 3000 systems upgraded to Series C infrastructure
Functional Role
This cable provides the physical and electrical interface between the Series C I/O Module and its associated termination hardware.
Primary functions include
Transmission of I/O data between controller and termination assembly
Distribution of module operating power
Transfer of diagnostic and status signals
Hardware-level module identification and integrity monitoring
The design ensures deterministic communication required for closed-loop control and critical process monitoring.
Electrical and Signal Characteristics
The 51202329-301 is constructed as a shielded multi-conductor industrial cable optimized for control system backplane and cabinet environments.
Key electrical features include
Shielded conductor architecture for EMI and RFI suppression

Neutral gray or black cable jacket consistent with Honeywell cabinet standards
The assembly is intended for fixed installation within control cabinets, marshalling panels, and system enclosures.
Environmental Performance
The 51202329-301 is designed to operate under the same environmental limits as Honeywell Series C I/O hardware.
Environmental suitability includes
Continuous operation in industrial temperature ranges
Resistance to cabinet-level humidity and airborne contaminants
Mechanical durability for long service life in stationary installations
Typical Applications
Used wherever Series C I/O modules are deployed within Honeywell control systems, including
Process automation cabinets
Distributed control system marshalling panels
Power generation and utilities
Oil, gas, chemical, and refining control rooms
FAQ
What does the 51202329-301 connect?
It links a Honeywell Series C I/O Module directly to an IOTA or IOTP, forming the internal communication and power path.
Can this cable be substituted with a generic cable?
No. Series C I/O cables use proprietary pinouts, shielding, and connector geometry. Generic cables may cause signal loss or system faults.
Is the cable field-terminable?
No. The cable is factory-terminated to ensure electrical integrity and correct mechanical engagement.
