I just started building my own plc trainer and wasn’t sure the analog input. This helped me out a lot to understand how it works. Thank you ! Looking forward to more videos.
@Dipsy Logic, nice concise video on the difference between analog and digital inputs, clearly presented. One suggestion; when you say that hooking up an analog device featuring a current output of 4-20 ma would not work when using the Micrologix 1100's analog inputs (3:18), you are selling the product short. Simply attach a 500 ohm resistor (1/4 W) across the two outputs of a 4-20 ma device to create a voltage drop that may now be measured at the ML1100's analog inputs in the range of 2-10 VDC. Make it a 250 ohm resistor and the input will be in the range of 1-5 VDC.
