When you're outfitting a machine or control panel, the first fork in the road is choosing between a display/interface kit and the programmable logic controller that runs the process. In many control panels you will eventually need both, so the real question is which one to buy first. This head-to-head compares two new options in the PLC-and-HMI space: the Infineon XMC4500 OLED Display Interface Kit and the Mitsubishi FX3U PLC.
Quick verdict
If your near-term goal is to work with an OLED-based operator interface, the Infineon XMC4500 OLED Display Interface Kit is the lower-cost way to start. If you need a programmable logic controller to execute automation, the Mitsubishi FX3U PLC is the one that addresses the control side. They are not interchangeable; they are simply two different layers of the same control-panel project.
At a glance
| Product | Listed Price | What it is | Best for |
|---|---|---|---|
| Infineon XMC4500 OLED Display Kit | USD 50.00 | Interface kit for an XMC4500 OLED display | HMI-style display development |
| Mitsubishi FX3U PLC | USD 116.96 | PLC processor module | Logic control in an automation setup |
Where each product wins
- The Infineon XMC4500 OLED Display Interface Kit wins on entry price and display-focused prototyping. Its part number, KIT_XMC4X_HMI_OLED_001, points to an interface-kit role, and it is the lower-priced item in this pair.
- The Mitsubishi FX3U PLC wins when the task is control. It is classified as a Programmable Logic Controller and a PLC processor module, so it maps to the logic side of an automation project.
Product notes
Infineon Technologies Kit Interface XMC4500 OLED Display KIT_XMC4X_HMI_OLED_001
This Infineon kit is the more display-focused option and the easier one on the wallet. It is described as new, and the KIT_XMC4X_HMI_OLED_001 part number marks it as an interface kit rather than a standalone controller. If you want to evaluate an OLED display or prototype an HMI-style operator panel, this gives you an affordable starting point without committing to a full PLC purchase. The trade-off is that no additional parts or accessories are included, so you should expect to supply whatever else your setup needs. So it is best treated as a display-and-interface starting point.
1PCS Brand New Mitsubishi PLC FX3U-32MT/ES-A Programmable Logic Controller
The Mitsubishi FX3U PLC is the higher-priced item in this comparison and sits on the opposite side of the PLC-and-HMI pairing. It is described as new, comes as a single unit, and is categorized as a PLC processor module under a Programmable Logic Controller platform. If your project needs a logic controller to make decisions and coordinate the rest of the panel, this is the option that matches that role. It is not the place to source a display layer; it is a controller-focused buy, so you would pair it with an HMI if your design calls for one. That makes it the stronger pick when your priority is the automation logic itself.
Final choice by use case
Choose the Infineon XMC4500 OLED Display Interface Kit when you are focused on the display layer and want the lower-priced starting point at USD 50.00. Choose the Mitsubishi FX3U PLC when you need the programmable logic controller to run the automation and you are willing to invest USD 116.96 for that control function. With a $66.96 spread between them, the decision is less about value and more about whether your next step is the operator interface or the controller behind it.
