Honeywell 51202329-605 I/O Link Cable B Green

Product Introduction

The 51202329-605 cable connects C300 Controller IOTAs to Series C IOTAs and IOMs inside a CCA cabinet. Honeywell builds this assembly as a passive, pre-terminated header cable with three drops. Additionally, the cable spans two cabinet sides front-and-back or the same side of adjacent cabinets.

This cable belongs to the Cable B redundancy pair, marked with a green label. Furthermore, Cable A (yellow label) and Cable B always operate together as a required pair. Each C300 Controller provides two I/O Links, namely IOL1 and IOL2. Specifically, the 51202329-605 plugs into IOL1B or IOL2B ports on the controller IOTA.

Technical Specifications

The Honeywell 51202329-605 cable family runs at 750 KBaud for Series C I/O Link communication. Moreover, each I/O Link delivers 2000 Link Units/sec throughput. One Link Unit equals one parameter read or write per second.

Link Capacity and Addressing

Each I/O Link supports a maximum of 40 I/O Units at 50 ms CEE. Therefore, IOTA address jumpers run from 1 to 40. The controller manages two links, so one C300 can address up to 80 units across IOL1 and IOL2.

Cable Configuration

This assembly is a header cable with 3 drops/taps. Besides, it supports 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 requires Cable A and Cable B as a matched pair for redundant I/O Link operation. The 51202329-605 serves as Cable B with its green label. However, each cable ships individually or as a pair, depending on the order.

Mechanical and Environmental Parameters

The cable jacket color is gray, matching the IOL1 link coding. Meanwhile, the assembly remains passive and carries no built-in ports or electronics. It 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 label before routing the cable. The 51202329-605 connects to the IOL1B or IOL2B port, marked by the green label. Next, route the header cable across the cabinet span defined by R301.1.

Then, seat each drop connector firmly into the matching IOTA drop port. Meanwhile, confirm the IOTA address jumpers sit within the 1 to 40 range. Finally, pair this Cable B with its Cable A counterpart to complete the redundant link.

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 is the difference between the 51202329-605 and its Cable A partner?
The 51202329-605 is Cable B with a green label. Cable A uses a yellow label. Honeywell requires both cables as a pair for redundant I/O Link operation.

Q2: How many I/O Units can one 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.

Q3: Which IOTA sizes work with this cable?
The assembly supports 6-inch, 9-inch, and 12-inch IOTAs. Moreover, extension cables reach up to 30 ft (9 m).

Q4: Does this cable 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 51202329-605 run at?
The cable supports 750 KBaud Series C I/O Link signaling. Furthermore, it delivers 2000 Link Units/sec throughput per link.
