The decision: cable plant or control rack?
When you are planning an industrial controls installation, the "control cables connectors io" shelf can put two very different parts side by side: a long reel of control cable and a remote I/O module that brings field inputs back to a controller. The Belden 2AS-1801POS-B-B/R is the cable side of that decision. The Honeywell NOVAR Opus XIO-8CTI-B is the control-rack side. One carries signals to the equipment; the other takes signals from current transformers and makes them readable to a system.
Quick verdict
If the missing piece is a long run of control cable, buy the Belden reel. If the missing piece is a current-transformer input module for a Novar Opus remote I/O setup, buy the Honeywell NOVAR module. At $641.24 for the Belden and $284.88 for the Honeywell, the price gap is real, but it is not the main story: the cable and the module do not overlap in function, so you pick whichever matches the stage of your project.
At a glance
| Product | Listed Price | What you are buying | Key detail |
|---|---|---|---|
| Belden 2AS-1801POS-B-B/R | $641.24 | 482 ft roll of 18 AWG industrial control cable | 600V, 90°C dry/wet |
| Honeywell NOVAR Opus XIO-8CTI-B | $284.88 | Remote I/O module for current-transformer input | 22-28VAC 50/60Hz |
Where each product wins
Belden wins if you need a long continuous supply of industrial control cable. This reel can complete a long pull without making an extra splice, and the cable's 600V classification with a 90°C dry/wet temperature rating suits plant control wiring. It is the more expensive item, and it earns that price by giving you a full reel of bulk cable ready for installation.
Honeywell NOVAR wins if you are working on a Novar Opus remote I/O system and need a CT input module. The XIO-8CTI-B is purpose-built for current-transformer inputs and has a defined AC supply requirement. It is the more targeted part: instead of bulk cable, you are buying a specific control component that fills a defined spot in the I/O architecture.
Product notes
Belden 2AS-1801POS-B-B/R Industrial Control Cable
If the missing piece is the wire itself, this Belden reel is built for the job. It is an 18 AWG industrial control cable in a 482-foot roll, so you have enough length for one long control circuit without splicing sections together. The condition is listed as New - Open box, which means the cable itself is new but the original packaging has been opened. Before you commit, think about whether your project requires sealed reels; if not, the open-box condition is a practical way to get a full industrial reel. For a straightforward plant control run, this is the part that completes the cable plant.
Honeywell NOVAR Opus XIO-8CTI-B Remote I/O Module
When your controller needs to read current-transformer inputs, the XIO-8CTI-B is the module you are looking for. It is a remote I/O current-transformer input module, listed as New, and it is made for a 22-28VAC 50/60Hz supply. The specific power requirement is the detail to check first: if your panel does not supply that AC range, the module will not be useful without additional power hardware. But when the supply matches, you get a purpose-built CT input component for a Novar Opus remote I/O setup. This is the piece that turns a current transformer's signal into something the system can act on.
Final choice by use case
If you are pulling cable between cabinets, the Belden reel is the buy. If you are adding current-transformer inputs to a Novar Opus remote I/O panel, the Honeywell NOVAR module is the buy. They do not replace each other; they belong to different stages of the same control-cables, connectors, and I/O project. Let your current bottleneck choose for you.
