Power Expansion Modules off RA Relay Block?

[SuperDodge]

Can I power my expansion relays off the Reef Angel itself or do they need to be powered from another source due to startup sequences, etc?

I'm up to three expansion devices needing 12v power and I don't have enough outlet space to do it neatly.

The Salinity and ORP expansion modules can't share same ground or you will have interferences and erroneous readings.

I was afraid of that. I'll have to install a power strip to the underside of my stand then.

Thanks for the clarification.
