- I built a MicroLogix 1100 PLC Trainer to use with an online course I'm taking. In the video I do a quick demonstration and then talk a bit about what I included in the trainer.

Happy learning
I need to connect the wires step by step to a possible video or detailed explanation in order to learn
Hi, I have just bought a Micrologix1100, and I am building a trainer. What is the main circuit breaker rating you are usings,or how do you calculate the rating, and what is the rating of output fuses you are using. I also don't understand why in PLCs, they use fuses for output and not for inputs.
Hi Jamal! I can't say that anything I do is necessarily right or wrong or best practice, but I'll layout what I did and why. Hope it helps!
The main breaker is rated for 2 amps. The reason is that the Omrom power supply I'm using is rated to pull 1.7 amps max, so I chose a breaker that was just a little more than that.
On the DC side, I have two fuses. the first is on the power connection for the PLC itself, and it's rated for 2 amps. I can't remember why I went with 2 amps, I may have picked that number up from the manual or elsewhere.
The other fuse is 250mA, and it feeds all of the inputs and outputs. Since I'm using LED indicators, there isn't a very high current draw, so this is more than enough. It's more than any single output can handle (100mA) so it's not perfect as far as protection goes, but it's primarily there to ensure if something does get shorted, that the power is cut. Given that I'm not adding/removing inputs and outputs, there's little chance of a short occurring. In a "real" configuration, it may be ideal to individually protect the I/O points.
Where can I find a 0-10v input module like that? How much was it?
The device on the right? It's a DROK signal generator from Amazon.com. I think it was around $30.
Thanks, the cheapest 4-20 simulator i've been able to find was around $200.
Did the course on Udemy go over how to set up a simple PID control loop? I'm thinking about building an electric bicycle and using an 1100's PID function for a cruise control setting, but I have no idea how to do something as complicated as PID control.
+Blake Gardner Sure! The class touches on PID control, but he uses a different PLC, a MicroLogix 1400 I believe. I tried to do PID once on my 1100 based on what I learned, but it keeps faulting the PLC so I moved on. Might be something I did wrong, not sure. The 10v analog signal did work though!
How much it cost you on everything?
Sorry, I didn't keep track!
It’s fine. I was debating on buying 1100 plc or the Click and make one just like yours but idk yet. thanks on your time anyway!
@@acclem3026 I built trainers with both the 1100 and a Click. I got my 1100 for $50 but it was sold untested and as-is. I got lucky! They usually go for a lot more. Personally I recommend the Click. The software is free and well supported and there's lots of information out there to help you get started.
Ah okay i see. Well, I probably go with click cause it’s cheaper. Reason why i need one it’s because we cant go back to school next semester. Due to CoViD19,
So now I have to do it online. Smh.
@@acclem3026 Good luck!
