When you're assembling control wiring, you might assume every "control cables connectors io" component answers the same question. It doesn't. The real decision is whether you need to connect cable runs into boxes or add I/O capacity to a control system. That's why the Arlington 38AST Snap2 IT connector lot and the Honeywell NOVAR Opus XIO-8CTI-B remote I/O module both belong in the same conversation, even though they do very different jobs.
Quick verdict
If your project is about wiring box connections, the Arlington 38AST lot is the straightforward choice with a lower listed price. If it's about expanding a Honeywell NOVAR Opus I/O station, the XIO-8CTI-B is the functional part you need. They are not interchangeable; the deciding factor is which stage of the control wiring chain you're working on.

Product notes
Arlington Industries 38AST 3/8" Snap2 IT Connector Lot of 50
The Arlington 38AST lot of 50 covers a lot of termination jobs in one box. The zinc die-cast fitting has an insulated throat, and the snap-in design lets you push the cable into the connector, snap it into the box, and tighten the top screw without needing separate assembly tools. It accepts cables ranging from .405 to .612 inches, which includes common MC/HCF and AC/HCF steel and aluminum cables. The 50-pack means you can wire several boxes or an entire small project without buying more. Its limitation is scope: it only handles cable termination. It cannot bring current transformer data into a control system, so if your bottleneck is I/O processing, this connector won't fix it. For a connector stock that's ready to use in a cable-heavy control build, this lot delivers.
Honeywell NOVAR Opus XIO-8CTI-B Remote I/O Module with CT 22-28VAC 50/60Hz NEW
The Honeywell NOVAR Opus XIO-8CTI-B is a different kind of component. It's a current transformer input module designed for the NOVAR Opus remote I/O lineup, operating on 22-28VAC at 50/60Hz. The module is new and listed with part number XIO-8CTI-B, model XIO.80CT, manufactured by CTI in Mexico. If your control system relies on current transformer inputs, this module gives you the dedicated input channel to bring those readings back to the controller. The limitation is the opposite of the connector lot: it's a single specialized module, and it doesn't terminate cable or handle mechanical connections. The higher listed price reflects its role as a functional I/O component. Choose this when the missing piece is CT input at the remote I/O level, not cable termination.
Final choice by use case
Choose the Arlington 38AST lot when your immediate need is cable connections: snapping cable into boxes, especially across multiple runs. Choose the Honeywell NOVAR Opus XIO-8CTI-B when you're building or expanding a NOVAR Opus remote I/O station. In short, ask whether your next step is making the physical connection or adding I/O capacity.
