Honeywell 51202329-601 Series C I/O Link Cable

Honeywell 51202329-601 Series C I/O Link Cable Assembly

Product Introduction

The 51202329-601 is a gray pre-terminated I/O Link cable assembly from Honeywell. It serves the Experion PKS Series C platform and connects the C300 Controller IOTA to Series C IOTAs and IOMs inside a CCA. Specifically, this order code represents Cable B with a green label, marked IOL1B or IOL2B. Additionally, the cable is a header type with three drops, and it distributes the I/O Link horizontally across the cabinet top. Furthermore, it chains to additional header or extension cables per R301.1. Therefore, the assembly supports cabinet-side spanning and multi-CCA coverage in one cabinet side or across sides.

Technical Specifications

The assembly operates on the Series C I/O Link at 750 KBaud. Each C300 Controller provides two I/O Links, namely IOL1 and IOL2, per EP03-300-511 Section 2.3.1. The link throughput reaches 2000 Link Units/sec for Series C I/O, where one Link Unit equals one parameter read or write per second. Moreover, a single I/O Link supports a maximum of 40 I/O Units at 50 ms CEE, and IOTA address jumpers are numbered 1 to 40. The connector text symbols are IOL1A/IOL1B for the gray IOL1 link or IOL2A/IOL2B for the violet IOL2 link. Besides, the cable supports 6-inch (152 mm), 9-inch (229 mm), and 12-inch (305 mm) IOTA sizes. Redundancy requires Cable A and Cable B as a pair, and Cable A carries a yellow label. However, this listing covers Cable B only, which Honeywell sells individually or as a pair. The assembly is passive, so it has no built-in ports and simply plugs into the IOTA and IOTA drop connectors.

Mechanical and Environmental Parameters

The jacket color is gray, which matches the IOL1 link coding. The assembly ships within the certified cabinet build, and the Series C platform holds EN 61326-1:2013 EMC and IEC/EN 61010-1 safety compliance per EP03-520-515. Therefore, the passive harness itself does not carry per-cable UL, CE, or CSA marking. Honeywell does not publish connector form factor, conductor gauge, jacket material, flame rating, per-cable weight, or per-cable temperature and IP rating for this passive order code. For instance, IOTA datasheets cover field-wiring terminals up to 14 AWG stranded wire but do not specify the I/O Link cable connector. Meanwhile, R301.1 publishes extension cable lengths of 9, 25, 36, and 48 inches plus a 30 ft (9 m) extension ceiling. However, the header and drop harness end-to-end length depends on installation and is not published. Finally, the UPC guide confirms that one I/O Link has a maximum practical limit of 40 addresses, which matches the published capacity.

Installation Guide

First, identify the IOL1B or IOL2B port on the C300 Controller IOTA. Next, route the gray header cable along the cabinet top and align the three drops with the target IOTAs. Then, seat each pre-terminated connector firmly into its IOTA drop connector. After that, chain additional header or extension cables as needed, staying within the 30 ft (9 m) extension ceiling. Finally, install the matching Cable A with the yellow label to complete the redundant pair. Therefore, keep Cable A and Cable B paired at all times for proper redundancy.

FAQ

Q1: What does the 51202329-601 cable connect?
A: It links the C300 Controller IOTA IOL1B or IOL2B port to Series C IOTAs and IOMs within a CCA or across a cabinet side.

Q2: How many drops does this header cable provide?
A: The assembly provides three drops and chains to additional header or extension cables per R301.1.

Q3: Is this Cable A or Cable B?
A: This is Cable B with a green label. Redundancy also needs Cable A with a yellow label, which Honeywell sells separately or as a pair.

Q4: What I/O Link speed and capacity does it support?
A: It runs at 750 KBaud and supports up to 40 I/O Units per link at 50 ms CEE.

Q5: Does Honeywell publish per-cable UL or CE certification?
A: No, the passive harness ships inside the certified Series C cabinet and carries no per-cable UL, CE, or CSA marking.
