When you're shopping for a remote I/O module, the immediate question is whether the module's input type and supply voltage match your cabinet. The MOXA ioLogik E1242-T and the Honeywell NOVAR Opus XIO-8CTI-B both fit the "remote I/O module" category, but they're aimed at different parts of that spectrum. The Moxa is an Ethernet remote I/O module powered at 12-36VDC; the NOVAR Opus is a current-transformer input module that runs on 22-28VAC at 50/60Hz. Their listed prices are just as distinct: USD 110.00 for the open-box Moxa versus USD 284.88 for the new Honeywell NOVAR unit.
Quick Verdict
If your control panel runs on DC and you want Ethernet-based I/O at the lower listed price, the MOXA ioLogik E1242-T is the straightforward pick. If you need a current-transformer input module for an AC-powered cabinet and prefer a new-in-original-packaging unit, the Honeywell NOVAR Opus XIO-8CTI-B is the more appropriate choice.
Comparison at a Glance
| Product | Listed Price | Price Bar | Key Highlights |
|---|---|---|---|
| MOXA ioLogik E1242-T Ethernet Remote I/O Module 12-36VDC Open Box | USD 110.00 | Moxa; New - Open box; Ethernet remote I/O | |
| Honeywell NOVAR Opus XIO-8CTI-B Remote I/O Module with CT 22-28VAC 50/60Hz NEW | USD 284.88 | Novar; New; Input Module Current Transformer; MPN XIO-8CTI-B |
The listed price difference is USD 174.88, with the Moxa module carrying the lower listed price. That gap buys you different capabilities: the Moxa's DC supply and open-box condition versus the NOVAR Opus module's AC supply and current-transformer input.
Where Each Product Wins
The MOXA ioLogik E1242-T wins for shoppers who need an Ethernet remote I/O module and are comfortable with a $110 open-box purchase. The title indicates 12-36VDC operation, and there's no merchant name attached to this listing.
The Honeywell NOVAR Opus XIO-8CTI-B wins for shoppers who need a current-transformer input module. Its listed voltage is 22-28VAC at 50/60Hz, it's listed as new in original packaging, and it comes from merchant M6-EbK-bToK.
Product Notes
MOXA ioLogik E1242-T Ethernet Remote I/O Module 12-36VDC Open Box
At USD 110.00, this is the lower-priced of the two listings. It's described as new, but without the original box; the seller notes the box was discarded and the item will be packed in protective bubble wrap. The title identifies it as an Ethernet remote I/O module powered by 12-36VDC, which makes it a fit for DC-powered control cabinets. The trade-off is the open-box condition: you get the unit itself but not the retail packaging. If your installation needs current-transformer inputs or AC power, this listing doesn't supply that capability, so it's best matched to an Ethernet/DC use case.
Honeywell NOVAR Opus XIO-8CTI-B Remote I/O Module with CT 22-28VAC 50/60Hz NEW
This listing carries a higher price at USD 284.88 and comes from merchant M6-EbK-bToK. It's a new-in-original-packaging remote I/O module with type 'Input Module Current Transformer' and model XIO.80CT. The part number XIO-8CTI-B, plus the 'CT' in the title, points to current-transformer input functionality. It's rated for 22-28VAC at 50/60Hz and lists a 16A figure. The stronger match is an AC-powered panel needing current-transformer inputs. On the flip side, the price is much higher than the Moxa, and if your cabinet runs on DC or doesn't require CT inputs, the extra spend may not deliver any benefit.
Final Choice by Use Case
- Choose the MOXA ioLogik E1242-T if you need an Ethernet remote I/O module and your supply voltage is 12-36VDC. The listed price is USD 110.00, and the only visible drawback is that it's an open-box unit.
- Choose the Honeywell NOVAR Opus XIO-8CTI-B if you need a current-transformer input module that runs on 22-28VAC at 50/60Hz. It's new, in original packaging, and listed at USD 284.88.
