Roadtesting the easyE4 Nano PLC: AC or DC, What's Your Preference?

I will be roadtesting the Eaton easyE4 Nano Programmable Logic Controller in the very near future. If you haven't heard about it, let me tell you a few facts:

 

The easyE4 nano programmable logic controllers combine timers, relays, counters, special functions, inputs and outputs into a compact device that is easily programmed. It provides an

exceptional level of flexibility together with a substantial savings of commissioning time and effort. The easyE4 is available in six styles with 12 I/O that can be expanded to 188 I/O points, which provides the ideal solution for material handling, HVAC, pump control, irrigation, lighting, energy management, industrial control, and home automation. The easyE4 nano programmable logic controller excels in traditional applications where multiple relays, timers and pushbuttons are used.

 

For the purpose of ordering the roadtest units, a question arose about the input voltage while discussing the roadtest with Eaton. The two types I am considering is 24VDC or 110-220VAC. While both versions are available, and I could get both, I just wanted to get a sense what would be a roadtester's preference. This is more a logistics question than a tech question. Both versions have the same functionality.

 

Here's the 24VDC version

    I will ask about the EasySoft7 software. But it seems there is a desire for both AC and DC. I will ask for both. I'll ask for these two models: Easy-E4-UC-12RC1 and Easy-E4-AC-12RC1 Randall --element1…

    Definitely DC, kind of places you use these devices often have limited access and very frequently need live commissioning and/or debugging. A 24V DC based solution may cost a little more (needs more 24V…

    When you talk about programming PLCs you talk about programmming in Ladder Diagrams, Instruction List, Structrued Text, Function Blocks languages. For this PLC it is used the Ladder Diagram language.

    24v is the industry standard and what we use for the Rockwell ones at work, whereas the 220-240v one would be more ideal for home users, as it doesnt involves extra costs.

    but personally 24v.

    24Vdc is standard I/O voltage in industry. Furthermore any expansion modules with solid state outputs will not be compatible with the 220V main module.

    On the other hand, these devices are widely used in fi greenhouse climatisation and so forth. In this world 220Vac is the norm: control valves, relays... all are 220V (bizarre since water is omnipresent).

    Great!

     

    I'm fine with both but if I get the DC one it will just be an excuse to get a PSU, something I've been holding off for quite a bit.

     

    I think the analog modules might be useful in the future but I can't think of anything to do with them so if I need it, I'll get it myself.

    Hi Randall rscasny  ,

    https://www.element14.com/community/servlet/JiveServlet/showImage/105-263779-914912/easy4.JPG

    There is a mistake in the table, the dash under "features/display" ist wrong for the base unit EASY-E4-UC-12RC1.

     

    easy-E4 - .C - .. ... - x1(P)

    AC, DC, UC - Power rating Type of supply voltage

    12 - Number of inputs/outputs (8in, 4out)

    Type of output: R-Relay T-Transistor A-Analog P-Temperature

    E - Expansion

    CX - Base device with LED diagnostics

    C - Base device with display and buttons

    1- Version

    P- Type with push in connection instead of with screw terminal connection.

     

    !!! Please look for the actual firmware version because some functions of the user software can be used just with the lastest firmware version.

    - > V1.2 or newer (if I remember V1.3 is actual ???).

     

    ( user manual, page 13)

    11/2018 New edition

    11/2018 V1.1

    Real-time clock characteristic curve Sample program Cat No. MEMORY-SUD-A1

    1/2019 V1.2

    ff Corrections

    2/2019 Added models EASY-E4- AC-... and EASY-E4-DC-4PE1; added AC, AV, PM, and RE function blocks

    4/2019 Webserver, E-Mail function, time response, micro SD card

    10/2019 ff Device versions with push in terminals,EASY-E4-AC (cULus)

     

    The SD-Card slot is for the user programmed software. Here can be inserted a micro SD card.

    (Programming languages: Ladder diagram (LD), Function Block Diagram (FBD), Structured Text (ST), and easy Device Programming (EDP) on device and in easySoft 7)

     

    Best Regards

    Gerald

    I am going to ask the sponsor for:

     

    Easy-E4-UC-12RC1 (quantity 3)

     

    and

     

    Easy-E4-AC-12RC1 (quantity 2)

     

    This is the basic. If anyone wanted to get the analog modules (Gerald mentioned) they would need to mention it in the roadtest application and I would ask the sponsor.

    I am not sure what that dash means because the datasheets and Eaton's website says it comes with a display.

    I checked again.

     

    I went to Eaton's site. And I looked at the datasheet's again, just as Cristian-Gyobo did. Both come with a display.

     

    Now, it looks like it comes with a slot for an SD card. So, you will get the software for programming.

    That's great.

     

    Does the DC version come with the screen and keypad or not?

     

    Thanks!

    I took the day off on Friday, so I am just catching up on my email.

     

    But the sponsor, Eaton, told me the software comes with the product.

    In the user guide for both models is specified "Base device with display". You can also see on the parts (PN: 197211 and PN:127215) webpages:

    https://datasheet.eaton.com/datasheet.php?model=197211&locale=en_GB&_lt=

    and
