When you're shopping for control cables, connectors, and I/O equipment for an industrial control panel, one of the first decisions is how to get field signals into your controller. The remote I/O module is the bridge between sensors, actuators, and your PLC or DCS, and the choice often comes down to protocol support, input type, and budget. Two new modules are worth considering side by side: the ODOT CN-8032, a Profinet IO remote I/O module, and the Honeywell NOVAR Opus XIO-8CTI-B, a current transformer input module. Their prices are nearly identical, so the difference lies in the jobs they are built for.
Quick Verdict Both modules are offered as new, so you're not choosing between new and refurbished condition. The asking prices are close, with fewer than $16 between the two. The real decision is the signal format your controller expects and the way the module brings that signal in. Look at your network's protocol and your input type before you pick.

Where Each Product Wins
- For a network built around the protocol listed on the ODOT CN-8032, the ODOT is the clear winner. It carries that protocol in its product name and model, so it removes guesswork for that kind of system.
- For a panel that needs the input type the Honeywell NOVAR XIO-8CTI-B lists, the Honeywell is the direct choice. It is built around that input function, with a supply voltage of 22-28VAC 50/60Hz and a 16A rating to back it up.
Product Notes
ODOT Remote I/O Module Profinet IO CN-8032
The ODOT CN-8032 is a brand-new remote I/O module with Profinet IO as its protocol. The model number CN-8032 matches its type, so there's no ambiguity about what you're getting. The main reason to choose it is this Profinet IO compatibility-if your control system speaks Profinet, this module fits right into that role. The Country of Origin is China, and the module is offered as new. The limitation is that it is not offered for other signal input types, so if your application needs a different input type, this won't be the direct match. If you're running a Profinet network, the ODOT is the straightforward pick.
Honeywell NOVAR Opus XIO-8CTI-B Remote I/O Module with CT
The Honeywell NOVAR Opus XIO-8CTI-B is a new current transformer input module, with a 22-28VAC 50/60Hz supply and a 16A rating. The reason to choose it is this CT input type, which is ideal for monitoring current in motors and other industrial loads. It also comes with the Honeywell NOVAR Opus name and is manufactured in Mexico. The module is offered as new, so it pairs modern condition with this specific input function. The limitation is protocol: if your network needs a different protocol, this module is not the one, so the ODOT is the alternative. If your panel needs to measure current and your control system can accept the CT input, the XIO-8CTI-B is the more targeted choice.
Final Choice by Use Case Pick the ODOT CN-8032 when your network uses the protocol it lists. Pick the Honeywell NOVAR XIO-8CTI-B when you need the input type it lists. The right module depends on the signal format your controller expects.
