Honeywell 51202329-302 Series C I/O Link Drop Cable

Honeywell 51202329-302 I/O Link Drop Cable Assembly

Product Introduction

The Honeywell 51202329-302 belongs to the Experion PKS Series C I/O Link cable family. This gray pre-terminated assembly connects a C300 Controller IOTA to Series C IOTAs and IOMs inside a CCA. Specifically, it serves as a drop cable with three taps, and its top connector plugs into a header cable.

Furthermore, the model ships as a redundant cable pair. Cable A carries a yellow label, while Cable B carries a green label. Both cables are always required together for redundant I/O Link operation. The link runs at 750 KBaud and supports up to 40 I/O Units per link with a 50 ms CEE. In addition, each C300 Controller provides two I/O Links, namely IOL1 and IOL2.

Technical Specifications

The list below summarizes the key parameters of the 51202329-302 cable assembly.

• Cable family: Series C I/O Link (IOL1), 750 KBaud

• Jacket color: Gray

• Redundancy variant: Cable pair, one Cable A yellow plus one Cable B green

• Cable type: Drop cable with 3 drops, special channel

• Channel layout: Two Control Firewalls (CF9), two C300 Controllers, and one 6-inch (152 mm) IOTA per R301.1

• Function: Passive I/O Link connection from C300 Controller IOTA to Series C IOTAs and IOMs

• I/O Links per C300 Controller: 2 (IOL1 and IOL2)

• Link throughput: 2000 Link Units/sec for Series C I/O

• Max I/O Units per link: 40 (50 ms CEE)

• IOTA connector text symbol: IOL1A/IOL1B (gray) or IOL2A/IOL2B (violet)

• Supported IOTA sizes: 6-inch (152 mm), 9-inch (229 mm), and 12-inch (305 mm)

• Built-in ports: None, because the assembly is a passive pre-terminated cable

Besides the electrical data, the assembly handles vertical multi-drop wiring inside a CCA. Therefore, it suits channel layouts that combine firewalls and controllers in one cabinet side. Meanwhile, the IOTA address jumpers are numbered 1 to 40, which matches the 40-unit limit per link.

Mechanical and Environmental Parameters

Honeywell publishes only limited mechanical data for these passive order codes. For instance, the official documents confirm the gray jacket color and the yellow and green pair labeling. However, the connector physical form factor, conductor gauge, jacket material, and flame rating are not published. Similarly, per-cable weight and per-cable temperature or IP rating remain unpublished.

The Series C platform itself is certified to EN 61326-1:2013 for EMC and IEC/EN 61010-1 for safety and LVD. This passive cable harness ships inside the certified cabinet assembly. Consequently, it does not carry per-cable UL, CE, or CSA marking. Please note that the published extension cable lengths are 9, 25, 36, and 48 inches, with a 30 ft (9 m) extension ceiling. The drop harness end-to-end length depends on the installation and is not published.

Installation Guide

First, mount the C300 Controller IOTA and the target Series C IOTAs inside the cabinet. Next, confirm the IOL1 or IOL2 port assignment, because the connector text symbol differs by link. Then, connect Cable A (yellow label) and Cable B (green label) as a pair. Plug the top connector of the drop cable into the header cable, and respect the 3-drop channel layout.

Additionally, chain extension cables only within the 30 ft (9 m) ceiling. Set the IOTA address jumpers from 1 to 40, and keep each link at or below 40 I/O Units. Finally, verify the 750 KBaud link signaling after power-up. Since the assembly is passive, no configuration software is needed for the cable itself.

FAQ

Q1: What is the main function of the 51202329-302 cable?
A: It is a passive I/O Link drop cable pair. It connects a C300 Controller IOTA to Series C IOTAs and IOMs in a CCA.

Q2: How does this drop cable differ from a header cable?
A: This assembly provides three drops in a special vertical channel. Its top connector plugs into a header cable instead of spanning the cabinet top.

Q3: Why must Cable A and Cable B be used together?
A: Honeywell defines this order code as a redundancy pair. Cable A is yellow and Cable B is green, and both are always required.

Q4: How many I/O Units can one I/O Link support?
A: Each link supports a maximum of 40 I/O Units with a 50 ms CEE. The IOTA address jumpers are numbered 1 to 40.

Q5: What link speed does the 51202329-302 use?
A: The assembly runs at 750 KBaud on the Series C I/O Link. This speed matches the Series C system cabling standard in R301.1.
