Description
The Honeywell CC12403 (Part number 1021621) is a specialized, high-integrity interface cable designed for use in the TDC 3000 and Experion PKS distributed control systems (DCS). It is primarily used to connect I/O modules to field termination assemblies (FTAs) or to facilitate communication between internal chassis components.

Country of Origin
This precision industrial cable is manufactured by Honeywell International in the United States, following strict aerospace-grade wiring standards to ensure long-term signal stability in process environments.
Application Fields
The CC12403 cable is a standard connectivity solution for Honeywell control platforms:
- TDC 3000 Systems: Connecting High-Level Analog Input (HLAI) or Digital Input (DI) modules to their respective termination boards.
- Experion PKS: Interfacing C200 or C300 controllers with remote I/O racks.
- Refinery Control Rooms: Linking critical safety systems (FSC/Safety Manager) to field marshaling cabinets.
- Power Generation: Used in turbine control systems where high-speed, noise-free signal transmission is mandatory.
Product Usage Instructions
- Routing: Avoid routing the CC12403 parallel to high-voltage power lines. If crossing power cables is necessary, do so at a 90° angle to minimize electromagnetic interference.
- Connection: Ensure the connector is fully seated and the thumbscrews or locking clips are tightened. A loose connection can result in intermittent “Bad PV” (Point Value) alarms in the DCS.
- Bend Radius: Maintain a minimum bend radius of at least 10 times the cable diameter to prevent internal conductor fatigue or shielding gaps.
- Labeling: Use the designated labeling space near the connectors to identify the “From” and “To” locations, which is vital for troubleshooting in dense marshaling cabinets.
- Grounding: Ensure the drain wire is connected at the designated ground point on the termination assembly to allow the shield to effectively bleed off induced noise.
Product Technical Description
The 1021621 / CC12403 cable is engineered for the “Quiet Room” or “Marshaling Rack” environment. Technically, it uses twisted-pair architecture to provide high common-mode rejection. Each conductor is finely stranded for flexibility and plated to resist oxidation. The internal shielding is designed to protect low-level 4-20mA signals or high-speed digital pulses from the cross-talk typically found in complex industrial cabinets containing hundreds of concurrent signal paths.
Q&A (Common Questions)
Q: Can I cut and splice this cable if it is too long? A: It is highly discouraged. Splicing breaks the integrity of the shielding and introduces impedance mismatches. It is best to coil the excess neatly and secure it with cable ties.
Q: Is the CC12403 suitable for outdoor burial? A: No. This is an indoor/cabinet-rated cable. If it must go outdoors, it should be housed in a sealed, rigid conduit.
Q: What is the difference between CC12403 and CC12401? A: These part numbers usually differ by the connector orientation (straight vs. 90-degree) or the specific pin-to-pin wiring configuration for different I/O module types.
Q: How do I test a suspected faulty cable? A: Use a high-quality multimeter to check for continuity on all pins and ensure there are no shorts between the conductors or between any conductor and the shield.
