When an industrial control panel needs a new link between a controller and a field device, the missing piece can be a simple cable or a smarter I/O module. That is the choice here: the Keyence OP-87529 Industrial Control Cable and the Honeywell NOVAR Opus XIO-8CTI-B Remote I/O Module. One is a direct wire for Keyence automation hardware; the other is a remote I/O node for a NOVAR Opus system. The right pick depends on whether your panel is missing a conductor or an input point.
Quick verdict
If you need a direct replacement cable for a Keyence control setup, the Keyence OP-87529 at USD 167.32 is the lower-cost route. If you need a remote I/O module, the Honeywell NOVAR Opus XIO-8CTI-B at USD 284.88 is the component made for that job. The USD 117.56 gap between them pays for the module's input capability, not for a brand name.
At a glance
| Product | Price | Price bar | Type | Made in |
|---|---|---|---|---|
| Keyence OP-87529 | USD 167.32 | Industrial control cable | Japan | |
| Honeywell NOVAR Opus XIO-8CTI-B | USD 284.88 | Current transformer input module | Mexico |
Where each product wins
- Keyence OP-87529 wins for a straightforward cable replacement, especially when your control setup uses the Keyence Automate platform.
- Honeywell NOVAR Opus XIO-8CTI-B wins for a remote I/O input module in a NOVAR Opus system, where the cable alone cannot do the job.
Product notes
Keyence OP-87529 Industrial Control Cable
This is a single new cable, model OP-87529, made in Japan for Keyence control equipment. If your panel already runs on the Keyence Automate platform, this cable is a direct replacement link that keeps wiring simple. It is also the lower-priced option in front of you, which matters when the job is only a wire between devices. The limitation is scope: a cable cannot accept a current-transformer input or act as a remote I/O node. If your application needs an input module instead of a conductor, this part will not be the missing piece.
Honeywell NOVAR Opus XIO-8CTI-B Remote I/O Module
This new module, listed with model XIO.80CT and part number XIO-8CTI-B, is built in Mexico and designed for current-transformer input. It runs on 22-28VAC 50/60Hz and is specified at 16A, which makes it a purpose-built component for a NOVAR Opus remote I/O system. At the higher end of this price pair, it does something the Keyence cable cannot: it brings current-transformer signals into the I/O network. The limitation is the reverse. For a simple cable run between Keyence controllers, this module is more hardware than the job requires and is priced above the cable.
Final choice by use case
- For a direct cable replacement in a Keyence control setup, choose the Keyence OP-87529.
- For a remote I/O input module in a NOVAR Opus system, choose the Honeywell NOVAR Opus XIO-8CTI-B.
