Hello,
This question might be a little simple for here but, here it goes...
A little intro to what we are trying to accomplish...Basically, we are trying to control a motor from two sources (24v). Its a three phase 0.75kW motor that needs to work whenever it recieves a signal from either source. However, both sources might be on at the same time as well, then it needs to still keep working until none of the sources are on. We thought about using a contactor but, we dont exactly know what type of a contactor is required. We cant use a regular contactor with a single coil as we cant have the 24v travelling between sources. I guess we can place diodes at each source but, we believe there are probably better ways of doing this. So, it would be great if we can get help on solving this in the simplest form. Btw, we usually use Siemens in our machines so, if anyone has part numbers as to which devices we should look at, that would be greatly appreciated as well. Thank you.
