is this possible?
i have a customer has has a large factory, he has 2 x 800amp supplies coming into the site and would like to switch between suppliers dependant on which is offering the cheapest rate at the time
he has automated software that will dictate when he wants switch between supplies
i need to be able to remotely control a plc that will switch the supplies
he has a ups system and generators as back up
i was thinking of using 2 x safety contactors on each supply controlled through pilz safety relays
any thoughts would be much appreciated
