Honeywell 51202329-606 Series C I/O Link Cable Pair

Product Introduction

The 51202329-606 assembly delivers both halves of a redundant I/O Link connection in one order. Honeywell packages Cable A (yellow label) and Cable B (green label) together as a matched pair. Moreover, both cables use a gray jacket and a pre-terminated header design with three drops.

These cables connect the C300 Controller IOTA to Series C IOTAs and IOMs inside a CCA cabinet. Additionally, the harness spans two cabinet sides front-and-back, or the same side of adjacent cabinets. Each cable plugs into the IOL1A/B or IOL2A/B ports on the controller IOTA.

Technical Specifications

The Honeywell 51202329-606 pair operates on the Series C I/O Link at 750 KBaud. Furthermore, each link delivers 2000 Link Units/sec throughput, where one Link Unit equals one parameter read or write per second.

Link Capacity and Addressing

Each I/O Link supports up to 40 I/O Units at 50 ms CEE. Therefore, IOTA address jumpers run from 1 to 40. The C300 Controller manages two links, so a single controller can address up to 80 units.

Cable Configuration

Both cables in this pair are header cables with 3 drops/taps. Besides, they support 6-inch (152 mm), 9-inch (229 mm), and 12-inch (305 mm) IOTA sizes. The connector text symbol reads IOL1A/IOL1B for the gray IOL1 link or IOL2A/IOL2B for the violet IOL2 link.

Redundancy Design

Honeywell always requires Cable A and Cable B together for redundant I/O Link operation. Specifically, the yellow label marks Cable A, while the green label marks Cable B. This 51202329-606 order code ships both cables as one pair, which simplifies spare stocking and commissioning.

Mechanical and Environmental Parameters

The jacket color is gray for both cables, matching the IOL1 link coding. Meanwhile, the assembly stays passive and carries no built-in ports or electronics. Each cable plugs directly into IOTA and IOTA drop connectors.

Honeywell certifies the Series C platform to EN 61326-1:2013 for EMC and IEC/EN 61010-1 for safety and LVD. In addition, this passive harness ships inside the certified cabinet assembly. Therefore, it does not carry per-cable UL, CE, or CSA marking.

Honeywell does not publish connector form factor, conductor gauge, jacket material, or per-cable temperature rating for this order code. Besides, no per-cable IP rating or weight figure appears in official documents.

Installation Guide

First, verify the controller IOTA port labels before routing either cable. The yellow Cable A connects to the IOL1A or IOL2A port. Next, route the green Cable B to the matching IOL1B or IOL2B port.

Then, seat each drop connector firmly into the corresponding IOTA drop port. Meanwhile, confirm the IOTA address jumpers sit within the 1 to 40 range. Finally, check both cables run in parallel paths to preserve redundancy.

Extension cables come in 9, 25, 36, and 48 inch lengths, with a 30 ft (9 m) ceiling. However, the header harness end-to-end length depends on cabinet topology. Honeywell does not publish a fixed length for this assembly, so plan routing on site.

FAQ

Q1: What does the 51202329-606 pair include?
The order ships one Cable A with a yellow label and one Cable B with a green label. Both cables share the gray IOL1 jacket and the three-drop header design.

Q2: Why does Honeywell require both cables together?
Redundant I/O Link operation needs two independent paths. Therefore, Cable A and Cable B always operate as a pair, and a single cable cannot provide redundancy alone.

Q3: How many I/O Units can each link support?
Each link handles up to 40 I/O Units at 50 ms CEE. Since the C300 offers two links, total capacity reaches 80 units.

Q4: Does this cable pair carry UL or CE marking?
No per-cable marking exists. Instead, the Series C platform holds EN 61326-1 and IEC/EN 61010-1 certification as a cabinet assembly.

Q5: What link speed does the 51202329-606 pair run at?
Both cables support 750 KBaud Series C I/O Link signaling. Furthermore, each link delivers 2000 Link Units/sec throughput.
