When you are working through control cabling and I/O connectivity, two very different solutions can end up in the same comparison: a used MOXA remote I/O module lot and a new Keyence control cable. One is a capacity purchase; the other is a connection purchase. Knowing which problem you are solving makes the choice straightforward.
Quick verdict
If your project is about adding I/O capacity, the MOXA Industrial Remote I/O Module Lot is the broad, high-channel-count choice. If your project is about replacing one cable in a working Keyence system, the Keyence OP-87529 Industrial Control Cable is the more direct solution.
At a glance
| Product | Listed price | Condition | What's included |
| MOXA Industrial Remote I/O Module Lot | USD 749.00 | Used | 14 MOXA modules, field power distributors, solid state relay, fuse holders |
| Keyence OP-87529 Industrial Control Cable | USD 190.00 | New | Single OP-87529 control cable |
Where each product wins
Where the MOXA lot wins
The MOXA lot brings a full spread of I/O in one purchase: an M-4410 analog output module, an M-3810 RTD temperature input module, six M-1800 digital input modules, four M-2801 relay output modules, and two M-7002 field power distributor modules. Add the Phoenix Contact QUINT-DIODE, the Crydom A2425 solid state relay, and the Eaton Bussmann DIN rail fuse holders, and you have a box of cabinet-building blocks rather than a single wire.
Where the Keyence cable wins
The OP-87529 carries the exact OP-87529 model designation. If the controller already has the needed port, this is a known quantity instead of a mix of used modules. It is also the lower listed price of the two, which makes sense when the job is a repair rather than an expansion.
Product notes
MOXA Industrial Remote I/O Module Lot
Start here if the project is about capacity. The lot brings a mix of analog output, RTD temperature input, digital input, and relay output modules, so it suits a cabinet being rebuilt or expanded. The catch is the condition story: the modules were removed from an industrial automation cabinet, were working when removed, and are clean and in good cosmetic condition, but they have not been tested since removal and are sold as shown. In a production environment, you would want to confirm each channel before wiring it into the process. For a buyer who can do that verification, this lot is a practical way to obtain a large number of I/O points in one go.
Keyence OP-87529 Industrial Control Cable
If your existing Keyence control setup simply lost its cable, the OP-87529 is the direct replacement. It is new, the model string matches, and the controller platform is Automate, so you avoid used-equipment uncertainty. The trade-off is scope: this is one cable, so it addresses the connection, not the amount of I/O available. If the real problem is that the cabinet is out of points, this purchase will not fix that. Treat this as the finishing part for a system that is already working, not as the foundation of a new I/O expansion.
Final choice by use case
Choose the MOXA Industrial Remote I/O Module Lot when your cabinet needs a broad I/O build-out and you are prepared to verify each module before it goes into service. Choose the Keyence OP-87529 Industrial Control Cable when you have a working Keyence control system and the only missing piece is a new, exact-model cable. The MOXA lot is the capacity play; the Keyence cable is the connection play.
