Deciding what to buy for control cables, connectors, and I/O work often comes down to scale. On one side, the MOXA industrial remote I/O module lot bundles multiple module types for a control cabinet. On the other, the CNLINKO 4-pin connector is a single waterproof connection point. You are not comparing two versions of the same part; you are deciding whether your project needs a full I/O foundation or just one cable connection.
Quick verdict
If you need multiple I/O channels in one purchase, the MOXA lot is the broad solution. If you need one solid sealed connector for a single signal or power run, the CNLINKO is the focused solution. The price difference matters only after you decide which scale of job you have.
At a glance
| Product | Listed Price | Price Bar | What It Gives You |
|---|---|---|---|
| MOXA Industrial Remote I/O Module Lot | USD 749.00 | 14 Moxa modules plus Phoenix Contact, Crydom, and Bussmann accessories for multi-channel I/O | |
| CNLINKO 4 Pin Power Industrial Connector Female Plug Waterproof IP67 Signal M20 | USD 13.62 | One bayonet-coupled 4-pin connector with IP67 protection, gold-plated contacts, and a 20 A rms rating |
Where each product wins
- The MOXA lot wins when your priority is breadth: analog output, RTD temperature input, digital input, relay output, and field power distribution modules in a single buy. It is aimed at someone refitting an industrial automation cabinet and comfortable with ex-cabinet hardware.
- The CNLINKO connector wins when your priority is a single, straightforward cable connection. Quarter-turn bayonet coupling and a 4-pin layout make it easy to wire, and its new condition is a clear contrast to the used MOXA lot.
Product notes
MOXA Industrial Remote I/O Module Lot
This lot is the choice when you want to start or refresh an industrial control cabinet in one purchase. It includes a Moxa M-4410 analog output module, 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 bundle came out of an industrial automation cabinet, with modules working when removed, clean, and in good cosmetic condition. The trade-off is that they were untested since removal and sold as shown, so used-gear acceptance is part of the deal.
CNLINKO 4 Pin Power Industrial Connector Female Plug
The CNLINKO is the leaner option: one female 4-pin plug for a signal or power cable, rated IP67 for water protection and suited for 14-12 AWG wire. Gold-plated contacts and a 20 A rms current rating make it a capable single connection, while the quarter-turn bayonet coupling keeps installation quick. It carries UL, CE, and RoHS certificates, which can make specification review easier. The clear limitation is scope: a single connector cannot supply analog, digital, relay, or temperature I/O channels the way the MOXA lot can. If the rest of your I/O is already handled and you only need a sealed connection point, this is the component to grab.
Final choice by use case
The MOXA lot is the move when you need a multi-channel I/O foundation and can accept the untested-since-removal condition at its $749.00 price. The CNLINKO connector is the move when you need a single new sealed plug and $13.62 matches the size of that job. If you are not ready to buy an entire module stack, start with the connector and plan the I/O expansion separately.
