The CSLabs documentation says "If you use in the system such inductive loads as electromagnets, solenoids, electromagnetic clutches – it is recommended to use separate 24V power supply for the mentioned receivers and separate for CSMIO / IP-S."

This to me suggests that you only need one power supply if you are just switching small loads, such as relays, and a decent size capacitor across the power inputs would remove any ripple, which might cause problems.

I do not intend to go the extra expense of a second power supply unless absolutely needed.
