In the PLC and HMI space, choosing a programmable logic controller for an automation project is often a part-number question. The Mitsubishi FX1S-20MR-ES/UL, also written as FX1S20MRESUL, is a specific controller presented here as a new-in-box unit for USD 102.00. That clarity helps if you already know whether this model belongs in your system.
Quick verdict
For someone who has narrowed down the selection to a Mitsubishi FX1S-series part, this is a direct purchase. The model is stated in two formats, so it is easy to match against your project notes.
Who it suits
This option makes sense for technicians, engineers, and hobbyists who are comfortable working with a fixed Mitsubishi PLC part number. If you're building a control panel or maintaining a machine that already uses the FX1S family, the part-number clarity takes some of the guesswork out of the purchase. It also works as a spare unit to keep on hand.
What stands out
The title is the most useful detail. It names the MITSUBISHI FX1S-20MR-ES/UL and gives the alternate designation FX1S20MRESUL, which helps when checking labels or cross-referencing part numbers. The description matches that by calling it a programmable logic controller, so there is no ambiguity about what you are buying.
Meaningful trade-offs
The trade-off is specificity. This is a fixed part number, so the decision is about whether this exact FX1S-20MR-ES/UL fits your application. The product is one controller, so the total project cost will scale only if you multiply that for multiple units or add other control components.
Bottom line
If the model number already matches your requirement list, this Mitsubishi PLC is an easy decision. It is a specific part number with a straightforward buying decision. If you are still comparing PLC families, keep it as a reference point while you finalize your specs.
New In Box MITSUBISHI FX1S-20MR-ES/UL FX1S20MRESUL Programmable Logic Controller
The new-in-box condition is the clearest reason to choose this unit, especially if you want a PLC that has not been through a prior installation. The USD 102.00 price is plainly stated, so you can map it against your budget. One limitation to keep in mind is that the price covers one controller rather than a multi-unit bundle.
