Quick take
Choosing among PLCs HMIs can come down to a practical tension: do you need a specific model designation, a new-condition unit, or a controller whose title matches a particular control format? These four options span a $32.84 listed-price range, but they are not interchangeable by name or condition.
For an explicitly new-in-box Mitsubishi unit, the FX1S-20MR-ES/UL is the focused pick. The Beckhoff EL3064 is the new, lowest-priced choice for buyers seeking that exact model. Unitronics Vision 120 is the used option, marked Programmable, while the IDEC choice is the one to consider when the SmartRelay CPU and 24VAC-DC wording are central to the requirement.
Listed-price comparison
| Controller | Condition | Key identifying detail | Listed price | Price position |
|---|---|---|---|---|
| MITSUBISHI FX1S-20MR-ES/UL | New | New In Box | USD 102.00 | |
| Unitronics Vision 120 | Used | Programmable; Vision 120 model | USD 89.90 | |
| BECKHOFF EL3064 | New | Model and MPN: EL3064 | USD 86.97 | |
| IDEC FL1E-H12RCA FL1F SMARTRELAY CPU | New | SmartRelay CPU; 24VAC-DC in title | USD 119.81 |
The pricing places the Beckhoff EL3064 at the low end and the IDEC SmartRelay CPU at the high end. The Mitsubishi and Unitronics controllers sit between those endpoints, so the deciding factor is likely to be the exact product name and condition rather than price alone.
Decision matrix
- Choose by exact Mitsubishi designation: Select the MITSUBISHI FX1S-20MR-ES/UL when the FX1S-20MR-ES/UL name and a New In Box designation are the key requirements.
- Choose by used condition and programmable feature: Select Unitronics Vision 120 if a used controller is suitable and the Programmable feature is relevant to your selection.
- Choose by EL3064 model match: Select the BECKHOFF EL3064 when EL3064 is the required model or MPN and a new-condition module is the target.
- Choose by SmartRelay CPU wording: Select the IDEC FL1E-H12RCA when the title's SmartRelay CPU and 24VAC-DC identifiers match the controller format you are seeking.
Product notes
MITSUBISHI FX1S-20MR-ES/UL FX1S20MRESUL Programmable Logic Controller
This Mitsubishi controller is the natural choice when the purchase is anchored to the FX1S-20MR-ES/UL designation. Its title explicitly says New In Box, and its condition is New, making condition and model recognition the central reasons to choose it. At USD 102.00, it occupies the middle of this four-item comparison rather than either price endpoint. That is its main limitation for a buyer deciding strictly by listed price: both the Beckhoff EL3064 and Unitronics Vision 120 are lower-priced. Choose this one for the named Mitsubishi controller and new-in-box wording, not merely because it is one of several PLC options.
Unitronics Vision 120 V120-22-UN2 Programmable Logic Controller
Unitronics Vision 120 is the option for a buyer comfortable choosing a used controller with the Programmable feature. The Vision 120 model name gives this choice a clear identity, and its USD 89.90 listed price is the second-lowest of the group. Its tradeoff is condition: it is used, and the item has scuffs and scratches. That makes it a more condition-sensitive choice than the three controllers marked New. Select Unitronics Vision 120 when its model name and programmable designation align with your need, while recognizing that its used presentation is a material distinction in this comparison.
BECKHOFF EL3064 Programmable Logic Controller Modules
The BECKHOFF EL3064 is the clearest pick for a buyer whose requirement centers on the EL3064 designation. Both the model and MPN are EL3064, and the condition is New. At USD 86.97, it is the lowest-priced controller in this group, giving it a straightforward price advantage without changing its model-specific role. The limitation is equally specific: the title and type identify this choice as an EL3064 module, so its usefulness is closely tied to needing that exact designation. Pick it when EL3064 is the deciding identifier and a new-condition module at the low end of the listed-price range fits the purchase.
IDEC FL1E-H12RCA FL1F SMARTRELAY CPU 24VAC-DC PLC
Choose the IDEC FL1E-H12RCA FL1F when SmartRelay CPU and 24VAC-DC are the terms that best match your requirement. Its MPN is FL1E-H12RCA, and the unit is marked New; the box was opened to verify contents. This is also the highest-priced option here at USD 119.81, which is the clearest limitation when comparing the four listed prices. The product is best suited to a model- and title-specific decision rather than a price-first choice. It is the direct fit for shoppers looking for the IDEC SmartRelay CPU wording and FL1E-H12RCA identifier.
Final recommendation by use case
Pick the BECKHOFF EL3064 for the exact EL3064 model/MPN at the lowest listed price. Choose the MITSUBISHI FX1S-20MR-ES/UL when New In Box and its precise Mitsubishi designation lead the decision. Select Unitronics Vision 120 when a used, programmable controller is appropriate. Go with the IDEC FL1E-H12RCA FL1F SMARTRELAY CPU when the SmartRelay CPU and 24VAC-DC identifiers matter more than having the lowest listed price.
