PLC beginner... needs little help

PLC beginner... needs little help

PLC beginner... needs little help

Hello everyone,
I'm really interested in playing with PLCs, i'm thinking of picking up a TECO GENIE II SG2, its relatively inexpensive. As for the power supply, instead of buying the TECO power supply, can I just use my laptop power adapter or a simple plugin 110VAC to 24VDC converter (like router power supply, only that is 12V) and use it with a DC Female Converter from ebay (the one in the picture)?

In the installation instructions it also recommends that you use a surge absorber, can you recommend any please.

I'm also open to other micro-controllers or other low cost PLC/PLR/PLD/PIC

Thank you

RE: PLC beginner... needs little help

I think the "cheapo PLC" discussion has been done before somewhere on this forum.  I'd suggest you not only need to learn basic ladder logic, but also it would be good to start learning proper industrial control wiring methods.  You could get set up for a couple or three hundred dollars and have hours of fun.  Think of the expense as "educational costs."

RE: PLC beginner... needs little help

That Teco unit is not technically a "PLC", it is what's referred to as a "smart relay". The programming is a little different from what you might see in PLCs if you "graduate" to the big leagues at some later date, so just be aware that what it teaches you is going to be relevant in a general way. But if you have zero experience in solid state control logic devices, it is a good place to start.

24VDC is 24VDC, where it comes from is irrelevant. But you have to be careful about the CAPACITY of the power supply. You may find that the cheap little "wall wart" style plug-in PS units have inadequate power capability to do anything real with them. Bit twiddling  inside of a router is not tough duty, so those little wall warts don't need to be very capable.

If you are looking for cheap, try Automation Direct's DL05 $119 and I think the programming software is free download.

RE: PLC beginner... needs little help

Postblaze777:  I think you have the DL05 confused with the Click series.

 The DL05 software costs about $300.   The Click is a fine little PLC that has a nice programming tool that will simulate its operation nicely. I happen to be programming one just now and took a break to check Eng-Tips just now.

Anyway the Click development tool is free and downloadable.
