I have eight different kV motors that I need to run from the same source. I cannot change the topology to have different sources for each motor. Ideally something that simply turns the relays on one at a time for five minutes at a time would be fine. I need to ensure with a degree of certainty that:
- Two or more motors cannot be run at the same time
- Between switching motors there should be a small dead time.
I cannot use a cheap (/chinese) relay board controller but it needs to come from a reputable supplier. I have read alot about using two contactors to INTERLOCK a motor to go forward and reverse but cannot find a way to daisy chain them. However the word interlock is defined for two devices, so it might be that I am missing the correct terminology to find the component.
Does anyone know of any topologies, hierarchies or components that could resolve this for me?
