In the control cables connectors io category, the biggest decision is usually about signal coverage: do you need one specific input type, or a broad set of I/O modules for an entire cabinet? That choice becomes concrete when you compare a $749.00 used MOXA Industrial Remote I/O Module Lot with a $284.88 new Honeywell NOVAR Opus XIO-8CTI-B current transformer input module. The MOXA lot is a multi-module package removed from an industrial automation cabinet. The Honeywell NOVAR is a single, new CT input module. Both are remote I/O modules, but they solve different problems.
Quick Verdict
For most control panels that need a range of I/O signals, the MOXA Industrial Remote I/O Module Lot at USD 749.00 gives you more coverage in one purchase than a single module. If you need exactly one new current transformer input module, the Honeywell NOVAR Opus XIO-8CTI-B at USD 284.88 is the lower-cost, more targeted alternative. The main trade-off is breadth of used modules versus a fresh single-purpose module.
At a Glance
| Feature | MOXA Industrial Remote I/O Module Lot | Honeywell NOVAR Opus XIO-8CTI-B |
| Price | USD 749.00 | USD 284.88 |
| Condition | Used | New |
| Contents | Analog output, RTD temp input, 6 digital inputs, 4 relay outputs, 2 field power distributors, plus diode, SSR, and fuse holders | Single current transformer input module |
| Best for | Multi-signal cabinet build or expansion | Adding a CT input module to an existing I/O setup |
Where Each Product Wins
MOXA lot wins on coverage and variety. You get a complete spread of modules in one lot, including digital inputs, relay outputs, an RTD temperature input, and an analog output module, along with supporting power distribution and protection components.
Honeywell NOVAR wins on new condition and clear focus. The XIO-8CTI-B is new in original packaging, rated 16A, and designed specifically for 22-28VAC 50/60Hz CT input applications, at a noticeably lower price.
Product Notes
MOXA Industrial Remote I/O Module Lot
The MOXA lot earns its place when you need multiple I/O types without sourcing modules separately. It bundles analog output, RTD input, digital input, relay output, and field power distribution in one used purchase, plus supporting protection components. The listing notes it was removed from an industrial automation cabinet and was working when removed, but it is untested since removal and sold as shown. That makes checking each module the practical limitation: each module should be checked before you rely on it in a live control system.
Honeywell NOVAR Opus XIO-8CTI-B Remote I/O Module with CT 22-28VAC 50/60Hz NEW
The Honeywell NOVAR takes a more focused approach. This listing is for one new current transformer input module, rated 16A, for 22-28VAC 50/60Hz control power. It arrives new in original packaging, so there is no previous service history to verify. The trade-off is that the listing contains only that single CT input module. If your control panel also needs digital inputs, relay outputs, analog outputs, or RTD inputs, you will need to source those separately. For a targeted CT input replacement or a new build with a known I/O list, it is a clean, direct match.
Final Choice by Use Case
Choose the MOXA lot if you're populating or expanding a control cabinet that needs a spread of analog, RTD, digital, and relay I/O, and you're comfortable working with used equipment that is untested since removal.
Choose the Honeywell NOVAR Opus XIO-8CTI-B if your application calls for a single current transformer input module, you want new hardware, and you prefer the lower entry price.
