MVP 2021 Flex727 Posted October 16, 2019 MVP 2021 Report Share Posted October 16, 2019 Maybe a little off-topic, but I need to have redundant power supplies (24V for the PLC) in a system. What is the best approach to this? Two power supplies running all the time in parallel or a relay that switches when a power supply fails? I'm not sure the relay would be fast enough to prevent the PLC and other related 24V hardware from going down. Any education in this area would be greatly appreciated. @Joe Tauser, do you have relevant experience with this? Quote Link to comment Share on other sites More sharing options...
