In the control cables, connectors, and I/O corner of industrial automation, the fork in the road is usually cable versus control hardware. On one side is an 850-foot Amphenol industrial wire spool priced at $91.00; on the other is a MOXA industrial remote I/O module lot priced at $749.00. One gives you a long run of black wire for making connections, while the other delivers a used bundle of analog, digital, and relay modules for building or expanding remote I/O. The right pick depends on what's already on your bench.
Quick Verdict
If the job is pulling new wire through a control panel or replacing worn runs, the 850-foot Amphenol spool at $91.00 is the cheaper, more direct way to get a large quantity of cable. If the job is adding remote I/O capability, the MOXA lot at $749.00 is the one that supplies the actual analog output, RTD input, digital input, and relay output modules. Because the MOXA modules are used and untested since removal, the sensible plan is to bench-test them before a live install. If you only need cable, the Amphenol spool avoids a much larger expense for hardware you do not need yet.
Comparison at a Glance
| Product | Price | Relative Price | Condition | Best For |
|---|---|---|---|---|
| 850 ft Full Spool Black Amphenol Industrial Wire/Cable | $91.00 | New - Open box | Bulk wiring runs and replacement cable | |
| MOXA Industrial Remote I/O Module Lot | $749.00 | Used | Expanding a control cabinet with analog/digital/relay I/O modules |
Where Each Product Wins
The Amphenol spool wins for cable volume and upfront cost. You get 850 feet of black industrial wire for $91.00, and because it is a full spool, you can cut the lengths you need instead of joining shorter pieces.
The MOXA lot wins for I/O functionality. The bundle includes an analog output module, an RTD temperature input module, six digital input modules, four relay output modules, two field power distributor modules, a solid-state relay, a diode module, and two DIN rail fuse holders. That is a ready source of I/O hardware for a substantial remote I/O build-out.
Product Notes
850 ft Full Spool Black Amphenol Industrial Wire/Cable
Start here when the task is moving wire, not building control logic. This Amphenol spool is new but open box, so the cable itself is the item you are paying for. At $91.00, it is the lower-priced option by a wide margin, and the 850-foot length means you can handle long pulls without splicing mid-run. The wire is black, carries a 3-pin configuration, and is built for a wire mounting type, which suits connection work in an industrial electrical setup. The limit is that a spool of wire is passive: it does not give you any analog, digital, or relay functionality. If your project requires adding I/O points, you would still need separate modules and a plan to terminate this cable into them, so this product is best reserved for the wiring phase of a job.
MOXA Industrial Remote I/O Module Lot
Choose this when you need the modules that make an industrial control system talk to field devices. The MOXA lot at $749.00 is the higher-priced item, but it includes a substantial collection: 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, two M-7002 field power distributor modules, a Phoenix Contact QUINT-DIODE/12-24DC/2x20/1x40, a Crydom A2425 solid-state relay, and two Eaton Bussmann DIN rail fuse holders. The condition is used, and the modules were working when removed from an industrial automation cabinet but are untested since removal. That is the main limitation: you need to verify each module before relying on it in a live system. If your need is bulk cabling instead of I/O hardware, this lot will not cover that part of the job.
Final Choice by Use Case
If you are outfitting a new panel or replacing a long trunk line, the Amphenol wire spool at $91.00 gives you 850 feet of cable at a much lower upfront price. If you are expanding or repairing remote I/O nodes and need analog, RTD, digital, and relay modules, the MOXA lot at $749.00 is the only one of the two that provides those components. A practical sequence for many integrators is to start with the MOXA lot for the control layer, then keep the Amphenol spool handy for the wiring between field devices and the I/O rack.
