When you're building or upgrading an industrial control panel, the first fork in the road is usually display versus logic. Do you need a touchscreen operator interface to let someone see machine status and enter setpoints, or do you need the programmable logic controller that actually executes the sequence? The Delta DOP-107EG HMI and the Mitsubishi FX3U PLC sit on opposite sides of that question, yet both are new control components in a similar price band. The right choice comes down to the role you need filled.
Quick Verdict
If your panel needs a touchscreen HMI for operator interaction, choose the Delta DOP-107EG. If your panel needs the logic controller itself and you already have a display solution, choose the Mitsubishi FX3U PLC.
Comparison at a Glance
| Consideration | Delta DOP-107EG HMI | Mitsubishi FX3U PLC |
|---|---|---|
| Primary role | HMI touch screen | Programmable logic controller |
| Listed price | USD 190.40 | USD 116.96 |
| Price bar | ||
| Condition | New | New |
Both are new units, so condition is not the deciding factor. The deciding factor is what you want the new component to do: show machine status or run the control logic.
Where Each Product Wins
- The Delta DOP-107EG wins when the missing piece is the touchscreen operator interface. It gives you the visible, interactive surface operators need to monitor the system and make changes.
- The Mitsubishi FX3U wins when the missing piece is the controller itself. It gives you the programmable logic component your panel needs to execute control sequences.
Product Notes
Delta DOP-107EG HMI
This Delta unit is the touchscreen side of the control panel. It is a new HMI touch screen, so it fits the job of giving operators a visible, interactive window into the machine. If you are adding an interface to an existing PLC, the Delta is the component that bridges the operator and the logic. It is positioned as an automation-focused controller platform, which makes sense for a panel that already has its control brain. On the downside, the Delta is an HMI, not a programmable logic controller. If you are starting from scratch with no controller yet, you would still need a separate PLC to run the sequence. That limitation is easy to miss if you focus only on the screen and forget that the interface cannot do the controlling by itself.
Mitsubishi FX3U PLC
This Mitsubishi is the logic side of the equation. It is a programmable logic controller, which is exactly what you need when the job is to execute control logic. For a new panel or a machine retrofit where the display is already handled, the Mitsubishi gives you the core controller you need for the project. The trade-off is that the Mitsubishi is not a touchscreen HMI, so it won't provide the operator interface on its own. If you need a screen for operator interaction, you would need to add a separate display component. For some buyers, that means extra integration work; for others, it is simply the correct starting point.
Final Choice by Use Case
If you already have a controller and need a touchscreen HMI to view and operate the system, the Delta DOP-107EG HMI is the one to get. If you are building a new control system and need the programmable logic controller first, the Mitsubishi FX3U PLC is the one to get at its listed price of $116.96.
